关于什么是jwt（json web token），还有jwt的工作流程我这边就不多介绍，主要给大家介绍一下SpringBoot中如何整合Security然后在添加jwt的支持。

通过SpringBoot+Security+JWT来实现token校验的过程。在生产环境中，对发布API增加授权保护是非常必要的一件事情，这里我们就是利用jwt生成token，利用token来进行接口安全验证。

在整合jwt之前，我们首先要在SpringBoot中整合security的模块，来实现基于security的授权控制。用过security的人都知道，它的功能无比的强大比shiro还要强大，但是今天我就介绍security中关于权限控制和是登录验证的这一块的功能。

1.在开始之前我们先在pom.xml中添加security和jwt的相关依赖，如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.4.3.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <properties>

    </properties>

        </dependency>
        <dependency>

        <!-- https://mvnrepository.com/artifact/io.jsonwebtoken/jjwt -->

            </plugin>
        </plugins>
    </build>
</project>

2.在application.properties中添加数据库和jpa还有jwt的相关配置。具体如下所示：

spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/security_db?useUnicode=true&characterEncoding=utf-8
spring.datasource.username=root
spring.datasource.password=220316
logging.level.org.springframework.security=info
spring.thymeleaf.cache=false
spring.jpa.hibernate.ddl-auto=update
spring.jpa.show-sql=true
spring.jackson.serialization.indent_output=true

# JWT 604800
jwt.header:Authorization
jwt.secret:mySecret
jwt.expiration:10
jwt.tokenHead:Bearer
jwt.route.authentication.path:auth/login
jwt.route.authentication.refresh:auth/refresh
jwt.route.authentication.register:"auth/register"

3.新建实体类，进行用户登录的授权验证。（这里我新建两个实体类，一个是用户实体类，一个是用户关系实体类）

用户实体类：SysUser

package org.security.entity;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import javax.persistence.*;
import java.util.ArrayList;
import java.util.Collection;
import java.util.Date;
import java.util.List;
@Entity
public class SysUser implements UserDetails {
    @Id
    @GeneratedValue
    private Long id;
    private String username;
    private String password;
    private Date lastPasswordResetDate;
    @ManyToMany(cascade = {CascadeType.REFRESH},fetch = FetchType.EAGER)
    private List<SysRole> roles;
    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public List<SysRole> getRoles() {
        return roles;
    }

    public void setRoles(List<SysRole> roles) {
        this.roles = roles;
    }

    public Date getLastPasswordResetDate() {
        return lastPasswordResetDate;
    }

    public void setLastPasswordResetDate(Date lastPasswordResetDate) {
        this.lastPasswordResetDate = lastPasswordResetDate;
    }

    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        List<GrantedAuthority> auths = new ArrayList<>();
        List<SysRole> roles = this.getRoles();
        for (SysRole role : roles) {
            auths.add(new SimpleGrantedAuthority(role.getName()));
        }
        return auths;
    }

    @Override
    public String getPassword() {
        return this.password;
    }

    @Override
    public String getUsername() {
        return this.username;
    }

    @Override
    public boolean isAccountNonExpired() {
        return true;
    }

    @Override
    public boolean isAccountNonLocked() {
        return true;
    }

    @Override
    public boolean isCredentialsNonExpired() {
        return true;
    }

    @Override
    public boolean isEnabled() {
        return true;
    }
}

因为SysUser实体类继承UserDetails接口，这个类是基于Security的安全服务。所以通过继承UserDetails这个类，我们就可以实现Security中相关的功能了，后面我们会具体介绍是怎么一回事。

用户关系实体类：SysRole

package org.security.entity;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
@Entity
public class SysRole {
    @Id
    @GeneratedValue
    private Long id;
    private String name;


    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

SysRole实体类是保存着用户的拥有什么样权限的实体类。和用户实体是多对一的关系，也就是一个用户可以拥有多个权限。

实体类创建好之后，我们就可以编写相应的dao，service，controller类来实现用户登录的功能了。这里我会新建一个login.html页面和index.html页面，来进行登录校验的和权限控制演示。

dao接口（这里我采用jpa来实现用户查询的功能）

package org.security.dao;
import org.security.entity.SysUser;
import org.springframework.data.jpa.repository.JpaRepository;
public interface SysUserRepository extends JpaRepository<SysUser, Long> {
    SysUser findByUsername(String username);
}

service业务类

package org.security.service;
import org.security.dao.SysUserRepository;
import org.security.entity.SysUser;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
public class CustomUserService implements UserDetailsService {
    @Autowired
    SysUserRepository userRepository;
    @Override
    public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException {
        SysUser user = userRepository.findByUsername(s);
        if (user == null) {
            throw new UsernameNotFoundException("用户名不存在");
        }
        System.out.println("s:"+s);
        System.out.println("username:"+user.getUsername()+";password:"+user.getPassword());
        System.out.println("size:"+user.getRoles().size());
        System.out.println("role:"+user.getRoles().get(0).getName());
        return user;
    }
}

controller控制类：

package org.security.controller;
import org.security.entity.Msg;
import org.springframework.security.access.prepost.PreAuthorize;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

/**
 * Created by linzhiqiang on 2017/10/26
 */
@Controller
public class HomeController {
    @RequestMapping("/")
    public String index(Model model) {
        Msg msg = new Msg("测试标题", "测试内容", "额外信息，只对管理员显示");
        model.addAttribute("msg", msg);
        return "index";
    }
    
    @PreAuthorize("hasAuthority('ROLE_USER')")
    @RequestMapping(value="/admin/test1")
    @ResponseBody
    public String adminTest1() {
        return "ROLE_USER";
    }
    
    @PreAuthorize("hasAuthority('ROLE_ADMIN')")
    @RequestMapping("/admin/test2")
    @ResponseBody
    public String adminTest2() {
        return "ROLE_ADMIN";
    }
}

login.html页面：

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8"/>
    <title>登录</title>
    <link rel="stylesheet" th:href="@{css/bootstrap.min.css}"/>

        }
        .starter-template {
            padding: 40px 15px;
            text-align: center;
        }
    </style>
</head>
<body>

    <div class="container">
        <div class="navbar-header">

        </div>
        <div id="navbar" class="collapse navbar-collapse">
            <ul class="nav navbar-nav">

    </div>
</nav>
<div class="container">
    <div class="starter-template">
        <p th:if="${param.logout}" class="bg-warning">已注销</p>
        <p th:if="${param.error}" class="bg-danger">有错误，请重试</p>
        <h2>使用账号密码登录</h2>
        <form class="form-signin" role="form" name="form" th:action="@{/login}" action="/login" method="post">
            <div class="form-group">
                <label for="username">账号</label>
                <input type="text" class="form-control" name="username" value="" placeholder="账号"/>
            </div>
            <div class="form-group">
                <label for="password">密码</label>
                <input type="password" class="form-control" name="password" placeholder="密码"/>
            </div>
            <input type="submit" id="login" value="Login" class="btn btn-primary"/>
        </form>
    </div>
</div>
</body>
</html>

index.html页面：

<!DOCTYPE html>

        }

        .starter-template {

        <div id="navbar" class="collapse navbar-collapse">
            <ul class="nav navbar-nav">

                <li><a th:href="@{http://www.baidu.com}">百度</a></li>
            </ul>
        </div>
    </div>
</nav>
<div class="container">
    <div class="starter-template">
        <h1 th:text="${msg.title}"></h1>
        <p class="bg-primary" th:text="${msg.content}"></p>
        <div sec:authorize="hasRole('ROLE_ADMIN')">
            <p class="bg-info" th:text="${msg.extraInfo}"></p>
        </div>
        <div sec:authorize="hasRole('ROLE_USER')">
            <p class="bg-info">无更多显示信息</p>
        </div>
        <form th:action="@{/logout}" method="post">
            <input type="submit" class="btn btn-primary" value="注销"/>
        </form>
    </div>
</div>
</body>
</html>

4.SpringBoot中配置基于security的支持，这里我有两个配置

一个是没有登录用户都跳转到login.html页面的配置：

package org.security.config;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
@Configuration
public class WebMvcConfig extends WebMvcConfigurerAdapter {
    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/login").setViewName("login");
    }
}

接下来就是security核心的配置类了：

package org.security.config;
import org.security.service.CustomUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpMethod;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.config.http.SessionCreationPolicy;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Bean
    protected UserDetailsService customUserService() {
        return new CustomUserService();
    }

    @Autowired
    public void configureAuthentication(AuthenticationManagerBuilder authenticationManagerBuilder) throws Exception {
        authenticationManagerBuilder
                // 设置UserDetailsService
                .userDetailsService(customUserService())
                // 使用BCrypt进行密码的hash
                .passwordEncoder(passwordEncoder());
    }

    // 装载BCrypt密码编码器
    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Bean
    public JwtAuthenticationTokenFilter authenticationTokenFilterBean() throws Exception {
        return new JwtAuthenticationTokenFilter();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(customUserService());
    }

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    @Override
    protected void configure(HttpSecurity httpSecurity) throws Exception {
        httpSecurity
                // 由于使用的是JWT，我们这里不需要csrf
//                .csrf().disable()
                // 基于token，所以不需要session
//                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
                .authorizeRequests()
                //.antMatchers(HttpMethod.OPTIONS, "/**").permitAll()
                // 允许对于网站静态资源的无授权访问
                .antMatchers(
                        HttpMethod.GET,
                        "/",
                        "/*.html",
                        "/favicon.ico",
                        "/**/*.html",
                        "/**/*.css",
                        "/**/*.js"
                ).permitAll()
                // 对于获取token的rest api要允许匿名访问
                .antMatchers("/auth/**").permitAll()
                .antMatchers("/admin/**").hasIpAddress("127.0.0.1")
                .antMatchers("/admin/**").access("hasAuthority('ROLE_ADMIN')")
                .anyRequest().authenticated().and().formLogin().loginPage("/login")
                .failureUrl("/login?error").permitAll().and().logout().permitAll();
        // 除上面外的所有请求全部需要鉴权认证
//				.anyRequest().authenticated();
        // 添加JWT filter
//        httpSecurity
//                .addFilterBefore(authenticationTokenFilterBean(), UsernamePasswordAuthenticationFilter.class);
        // 禁用缓存
//        httpSecurity.headers().cacheControl();
    }
}

这里我暂时先把jwt相关的代码先注释掉，将注解取消掉的话，就可以实现jwt相关的功能了。

5.打开浏览器进行功能测试，下面是测试的结果：

如果未登录的话，就都会跳转到这个login.html登录页面

登录成功后进入的index页面，这里测试的账户权限类型是admin，下面有两个地址一个是admin/test1只能user权限才可以访问，还有一个是admin/test2拥有admin权限的人才可以访问，下面我们开始测试。

因为权限不够所以，返回的是403错误。

权限够的话，返回的是这个接口获取的数据。

到这里关于SpringBoot整合Security就介绍完了，接下来就是如何添加jwt的支持了。

6.基本过程和security差不多：

一：首先创建一个工具类，用来生成jwt的token和token的验证刷新之类的。

二：然后创建一个fiter类，并配置注入security配置文件中

三：接下来就是创建dao，service，controller来实现接口。

四：最后就是利用postman来测试是否实现jwt功能

工具类JwtTokenUtil：

package org.security.util;
import io.jsonwebtoken.Claims;
import io.jsonwebtoken.Jwts;
import io.jsonwebtoken.SignatureAlgorithm;
import org.security.entity.SysUser;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.stereotype.Component;
import java.io.Serializable;
import java.util.Date;
import java.util.HashMap;
import java.util.Map;

@Component
public class JwtTokenUtil implements Serializable {

    private static final long serialVersionUID = -3301605591108950415L;

    private static final String CLAIM_KEY_USERNAME = "sub";
    private static final String CLAIM_KEY_CREATED = "created";

    @Value("${jwt.secret}")
    private String secret;

    @Value("${jwt.expiration}")
    private Long expiration;

    public String getUsernameFromToken(String token) {
        String username;
        try {
            final Claims claims = getClaimsFromToken(token);
            username = claims.getSubject();
        } catch (Exception e) {
            username = null;
        }
        return username;
    }

    public Date getCreatedDateFromToken(String token) {
        Date created;
        try {
            final Claims claims = getClaimsFromToken(token);
            created = new Date((Long) claims.get(CLAIM_KEY_CREATED));
        } catch (Exception e) {
            created = null;
        }
        return created;
    }

    public Date getExpirationDateFromToken(String token) {
        Date expiration;
        try {
            final Claims claims = getClaimsFromToken(token);
            expiration = claims.getExpiration();
        } catch (Exception e) {
            expiration = null;
        }
        return expiration;
    }

    private Claims getClaimsFromToken(String token) {
        Claims claims;

dao接口： 

package org.security.dao;
import org.security.entity.SysUser;
public interface AuthService {
    SysUser register(SysUser userToAdd);
    String login(String username, String password);
    String refresh(String oldToken);
}

dao接口实现类（service业务类）： 

package org.security.service;
import org.security.dao.AuthService;
import org.security.dao.SysUserRepository;
import org.security.entity.SysUser;
import org.security.util.JwtTokenUtil;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.stereotype.Service;

import java.util.Date;

import static java.util.Arrays.asList;

@Service
public class AuthServiceImpl implements AuthService {

    private AuthenticationManager authenticationManager;
    private UserDetailsService userDetailsService;
    private JwtTokenUtil jwtTokenUtil;
    private SysUserRepository userRepository;

    @Value("${jwt.tokenHead}")
    private String tokenHead;

    @Autowired
    public AuthServiceImpl(
            AuthenticationManager authenticationManager,
            UserDetailsService userDetailsService,
            JwtTokenUtil jwtTokenUtil,
            SysUserRepository userRepository) {
        this.authenticationManager = authenticationManager;
        this.userDetailsService = userDetailsService;
        this.jwtTokenUtil = jwtTokenUtil;
        this.userRepository = userRepository;
    }

    @Override
    public SysUser register(SysUser userToAdd) {
        final String username = userToAdd.getUsername();
        if(userRepository.findByUsername(username)!=null) {
            return null;
        }
        BCryptPasswordEncoder encoder = new BCryptPasswordEncoder();
        final String rawPassword = userToAdd.getPassword();
        userToAdd.setPassword(encoder.encode(rawPassword));
        userToAdd.setLastPasswordResetDate(new Date());
//        userToAdd.setRoles(asList("ROLE_USER"));
        return userRepository.save(userToAdd);
    }

    @Override
    public String login(String username, String password) {
        UsernamePasswordAuthenticationToken upToken = new UsernamePasswordAuthenticationToken(username, password);
        // Perform the security
        final Authentication authentication = authenticationManager.authenticate(upToken);
        SecurityContextHolder.getContext().setAuthentication(authentication);
        // Reload password post-security so we can generate token
        final UserDetails userDetails = userDetailsService.loadUserByUsername(username);
        final String token = jwtTokenUtil.generateToken(userDetails);
        return token;
    }

    @Override
    public String refresh(String oldToken) {
        final String token = oldToken.substring(tokenHead.length());
        String username = jwtTokenUtil.getUsernameFromToken(token);
        SysUser user = (SysUser) userDetailsService.loadUserByUsername(username);
        if (jwtTokenUtil.canTokenBeRefreshed(token, user.getLastPasswordResetDate())){
            return jwtTokenUtil.refreshToken(token);
        }
        return null;
    }
}

controller控制类： 

package org.security.controller;
import org.security.dao.AuthService;
import org.security.entity.SysUser;
import org.security.service.JwtAuthenticationRequest;
import org.security.service.JwtAuthenticationResponse;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.http.ResponseEntity;
import org.springframework.security.core.AuthenticationException;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpServletRequest;

@RestController
public class AuthController {
    @Value("${jwt.header}")
    private String tokenHeader;

    @Autowired
    private AuthService authService;

    @RequestMapping(value = "/auth/login", method = RequestMethod.POST)
    public ResponseEntity<?> createAuthenticationToken(
            String username,String password
    ) throws AuthenticationException{
        //  @RequestBody JwtAuthenticationRequest authenticationRequest
        final String token = authService.login(username,password);

        // Return the token
        return ResponseEntity.ok(new JwtAuthenticationResponse(token));
    }

    @RequestMapping(value = "/auth/refresh", method = RequestMethod.GET)
    public ResponseEntity<?> refreshAndGetAuthenticationToken(
            HttpServletRequest request) throws AuthenticationException{
        String token = request.getHeader(tokenHeader);
        String refreshedToken = authService.refresh(token);
        if(refreshedToken == null) {
            return ResponseEntity.badRequest().body(null);
        } else {
            return ResponseEntity.ok(new JwtAuthenticationResponse(refreshedToken));
        }
    }

    @RequestMapping(value = "${jwt.route.authentication.register}", method = RequestMethod.POST)
    public SysUser register(@RequestBody SysUser addedUser) throws AuthenticationException{
        return authService.register(addedUser);
    }
}

接在来就是最重要的filter类：

package org.security.config;
import java.io.IOException;
import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.security.util.JwtTokenUtil;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.web.authentication.WebAuthenticationDetailsSource;
import org.springframework.stereotype.Component;
import org.springframework.web.filter.OncePerRequestFilter;

@Component
public class JwtAuthenticationTokenFilter extends OncePerRequestFilter {

    @Autowired
    private UserDetailsService userDetailsService;

    @Value("${jwt.header}")
    private String tokenHeader;

    @Value("${jwt.tokenHead}")
    private String tokenHead;

    @Autowired
    private JwtTokenUtil jwtTokenUtil;
    @Override
    protected void doFilterInternal(
            HttpServletRequest request,
            HttpServletResponse response,
            FilterChain chain) throws ServletException, IOException {
        String authHeader = request.getHeader(this.tokenHeader);
        if (authHeader != null && authHeader.startsWith(tokenHead)) {
            final String authToken = authHeader.substring(tokenHead.length()); // The part after "Bearer "
            String username = jwtTokenUtil.getUsernameFromToken(authToken);
            logger.info("checking authentication " + username);
            if (username != null && SecurityContextHolder.getContext().getAuthentication() == null) {
                UserDetails userDetails = this.userDetailsService.loadUserByUsername(username);
                	if (jwtTokenUtil.validateToken(authToken, userDetails)) {
                        UsernamePasswordAuthenticationToken authentication = new UsernamePasswordAuthenticationToken(
                                userDetails, null, userDetails.getAuthorities());
                        authentication.setDetails(new WebAuthenticationDetailsSource().buildDetails(
                                request));
                        logger.info("authenticated user " + username + ", setting security context");
                        SecurityContextHolder.getContext().setAuthentication(authentication);
                    }
            }
        }
        chain.doFilter(request, response);
    }
}

将security中配置文件注解去掉，去掉之后如下所示： 

package org.security.config;

import org.security.service.CustomUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpMethod;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.config.http.SessionCreationPolicy;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Bean
    protected UserDetailsService customUserService() {
        return new CustomUserService();
    }

    @Autowired
    public void configureAuthentication(AuthenticationManagerBuilder authenticationManagerBuilder) throws Exception {
        authenticationManagerBuilder
                // 设置UserDetailsService
                .userDetailsService(customUserService())
                // 使用BCrypt进行密码的hash
                .passwordEncoder(passwordEncoder());
    }

    // 装载BCrypt密码编码器
    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Bean
    public JwtAuthenticationTokenFilter authenticationTokenFilterBean() throws Exception {
        return new JwtAuthenticationTokenFilter();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(customUserService());
    }

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    @Override
    protected void configure(HttpSecurity httpSecurity) throws Exception {
        httpSecurity
                // 由于使用的是JWT，我们这里不需要csrf
                .csrf().disable()
                // 基于token，所以不需要session
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
                .authorizeRequests()
                .antMatchers(HttpMethod.OPTIONS, "/**").permitAll()
                // 允许对于网站静态资源的无授权访问
                .antMatchers(
                        HttpMethod.GET,
                        "/",
                        "/*.html",
                        "/favicon.ico",
                        "/**/*.html",
                        "/**/*.css",
                        "/**/*.js"
                ).permitAll()
                // 对于获取token的rest api要允许匿名访问
                .antMatchers("/auth/**").permitAll()
                .antMatchers("/admin/**").hasIpAddress("127.0.0.1")
                .antMatchers("/admin/**").access("hasAuthority('ROLE_ADMIN')")
//                .anyRequest().authenticated().and().formLogin().loginPage("/login")
//                .failureUrl("/login?error").permitAll().and().logout().permitAll();
        // 除上面外的所有请求全部需要鉴权认证
				.anyRequest().authenticated();
        // 添加JWT filter
        httpSecurity
                .addFilterBefore(authenticationTokenFilterBean(), UsernamePasswordAuthenticationFilter.class);
        // 禁用缓存
        httpSecurity.headers().cacheControl();
    }
}

到这边jwt整合也介绍了，现在我们就可以postman来进行测试。

测试结果如下所示： 生成token：

刷新token：

不带token访问接口:

带token但是权限不够：

带token而且权限也够：

到这里关于 SpringBoot+SpringSecurity+JWT就基本结束了，这篇博客我重点是将如何通过代码来实现这个功能，关于代码本身没有很细致的介绍。关于代码功能的介绍，例如怎么通过注解配置权限控制，如何通过配置来进行权限控制，token更新和验证等等的细节，我会在我这篇博客的教学视频中介绍，视频地址：点击打开链接
