前言

       上一篇:spring-boot-2.0.3不一样系列之国际化,讲了如何实现国际化,实际上我工作用的模版引擎是freemaker,而不是thymeleaf,不过原理都是相通的。

       接着上一篇,这一篇我来讲讲spring-boot如何整合工作中用到的一个非常重要的功能:安全,而本文的主角就是一个安全框架:shiro。

       Apache Shiro是Java的一个安全框架。目前,使用Apache Shiro的人也越来越多,因为它相当简单,对比Spring Security,可能没有Spring Security的功能强大,但是在实际工作时可能并不需要那么复杂的东西,所以使用小而简单的Shiro就足够了。对于它俩到底哪个好,这个不必纠结,能更简单的解决项目问题就好了。

摘自开涛兄的《跟我学Shiro》

       本文旨在整合spring-boot与shiro,实现简单的认证功能,shiro的更多使用细节大家可以去阅读《更我学shiro》或者看官方文档https://shiro.apache.org/reference.html

  本文项目地址:spring-boot-shiro

spring-boot整合shiro

       集成mybatis

    Shiro不会去维护用户、维护权限;这些需要我们自己去设计/提供,然后通过相应的接口注入给Shiro;既然用户、权限这些信息需要我们自己设计、维护,那么可想而知需要进行数据库表的设计了(具体表结构看后文),既然涉及到数据库的操作,那么我们就先整合mybatis,实现数据库的操作。

       开启logback日志

    其实上面的pom配置已经引入了日志依赖,如图:

    但是你会发现,spring-boot-starter-logging引入了3种类型的日志,你用其中任何一种都能正常打印日志;但是我们需要用3种吗?根本用不到,我们只要用一种即可,至于选用那种,全凭大家自己的喜欢;我了,比较喜欢logback(接触的项目中用的比较多,说白了就是这3种中最熟悉的把);我们来改下pom.xml,重新配置日志依赖:

    加入controller,处理web请求,具体代码参考:spring-boot-shiro

用post测试下,出现下图,表示web开启成功

              配置druid监控后台

      可配可不配,但是建议配置上,它能提供很多监控信息,对排查问题非常有帮助,配置好后,界面如下

      提供的内容还是非常多的,更多的druid配置大家可以查看druid官网

          druid配置只需要在application.yml中加入druid配置,同时在config目录下加上DruidConfig.java配置文件即可,具体内容可参考:spring-boot-shiro

  集成shiro,并用redis实现shiro缓存

    集成shiro非常简单,我们只需要将用户、权限信息传给shiro即可。表结构信息:

代码语言:javascript
复制
DROP TABLE IF EXISTS `tbl_user`;
CREATE TABLE `tbl_user` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT COMMENT '自增主键',
  `username` varchar(50) NOT NULL COMMENT '名称',
  `password` char(32) NOT NULL COMMENT '密码',
  `salt` char(32) NOT NULL COMMENT '盐,用于加密',
  `state` tinyint(2) NOT NULL DEFAULT '1' COMMENT '状态, 1:可用, 0:不可用',
  `description` varchar(50) DEFAULT '' COMMENT '描述',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='用户表';

    shiro的缓存也是提供的接口,我们实现该接口即可接入我们自己的缓存实现,至于具体的缓存实现是redis、memcache还是其他的,shiro并不关心;而本文用redis实现shiro的缓存。采用spring的redisTemplate来操作redis,具体的实现,如下

    ShiroRedisCacheManager:

代码语言:javascript
复制
package com.lee.shiro.config;

import org.apache.shiro.cache.Cache;
import org.apache.shiro.cache.CacheException;
import org.apache.shiro.cache.CacheManager;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
public class ShiroRedisCacheManager implements CacheManager {

    @Autowired
    private Cache shiroRedisCache;

    @Override
    public <K, V> Cache<K, V> getCache(String s) throws CacheException {
        return shiroRedisCache;
    }
}

    ShiroRedisCache:

代码语言:javascript
复制
package com.lee.shiro.config;

import org.apache.shiro.cache.Cache;
import org.apache.shiro.cache.CacheException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Component;

import java.util.Collection;
import java.util.Set;
import java.util.concurrent.TimeUnit;

@Component
public class ShiroRedisCache<K,V> implements Cache<K,V>{

    @Autowired
    private RedisTemplate<K,V> redisTemplate;

    @Value("${spring.redis.expireTime}")
    private long expireTime;

    @Override
    public V get(K k) throws CacheException {
        return redisTemplate.opsForValue().get(k);
    }

    @Override
    public V put(K k, V v) throws CacheException {
        redisTemplate.opsForValue().set(k,v,expireTime, TimeUnit.SECONDS);
        return null;
    }

    @Override
    public V remove(K k) throws CacheException {
        V v = redisTemplate.opsForValue().get(k);
        redisTemplate.opsForValue().getOperations().delete(k);
        return v;
    }

    @Override
    public void clear() throws CacheException {
    }

    @Override
    public int size() {
        return 0;
    }

    @Override
    public Set<K> keys() {
        return null;
    }

    @Override
    public Collection<V> values() {
        return null;
    }
}

    更详细、完整的代码请参考spring-boot-shiro,上文的缓存只是针对realm缓存,也就是权限相关的,至于其他缓存像session缓存,大家可以自行去实现。

效果展示

  经过上述的步骤,工程已经搭建完毕我们来验证下效果

  druid后台监控

    如下图

    在shiro配置中,我们放行了/druid/**,所以druid后台的地址都没有被拦截,druid相关的由druid自己控制,不受shiro的影响。

  shiro权限控制

    由spring-boot-shiro.sql、UserController.java可知,5个用户中只有admin和brucelee有/user/userList、/user/userAdd、/user/userDel的访问权限,而/user/findUserByUsername没做权限限制,那么5个用户都可以访问;但是登录是必须的(5个用户的密码都是123456);效果如下:

    上图中展示了zhangsan用户和admin权限访问的情况,完全按照我们设想的剧本走的,剩下的用户大家可以自己去测试;另外还可以多设置一些权限来进行验证。

  预祝大家搭建成功,如果有什么问题,可以@我,或者直接和我的代码进行比较,找出其中的问题。

疑问与解答

  1、我不修改日志依赖,但是我只用其中的某种日志打印日志不就行了,不会冲突也能正常打日志,为什么要修改日志依赖?

    说的没错,你不修改依赖也能正常工作,还不用书写更多的pom配置;但是你仔细去观察的话,你会发现你工程打包出来的时候,这些依赖的日志jar包全在包中,项目部署的时候,这些jar都会加载到内存中的,你没用到的日志jar也会加载到内存中,数量少、jar包小还能接受,一旦无用的jar包数量多、jar文件太大,那可想而知会浪费多少内存资源;内存资源不比磁盘,是比较稀有的。

    强烈建议把无用的依赖剔除掉,既能节省资源、也能避免未知的一些错误。

  2、日志依赖:为什么按文中的配置就能只依赖logback了

    maven的依赖有两个原则:最短路径原则、最先声明原则;以我们的pom.xml为起点,那我们自定义的spring-boot-starter-logging依赖路径肯定最短了,那么maven就会选用我们自定义的spring-boot-starter-logging,所以就把spring-boot-starter-logging的依赖全部剔除了,而<scope>test<scope>,大家都懂的;至于最先声明原则,也就说在路径相同的情况下,谁在前声明就依赖谁。

  3、遇到的一个坑,认证通过后,为什么授权回调没有被调用

    首先要明白,认证与授权触发的时间点是不同的,登录触发认证,但是登录成功后不会立即触发授权的;授权是有权限校验的时候才触发的;大家请看下图

    登录只是触发了认证、当有权限校验的时候才会授权(角色校验的时候也会),第一次权限校验请求数据库,数据会缓存到redis中,下次权限校验的时候就从缓存中获取,而不用再从数据库获取了。

    另外shiro注解生效是配置两个bean的,defaultAdvisorAutoProxyCreator和authorizationAttributeSourceAdvisor,我在这个问题上卡了一段时间;只配置authorizationAttributeSourceAdvisor没用,代理没打开,shiro注解的代理类就不会生成,注解配置了相当于没配置,这里需要大家注意。
