一、数据库准备

1、创建数据库及表sql语句

CREATE DATABASE vuejsdemo;
USE vuejsdemo;
CREATE TABLE USER (
	id INT PRIMARY KEY AUTO_INCREMENT,
	age INT,
	username VARCHAR ( 20 ),
	PASSWORD VARCHAR ( 50 ),
	email VARCHAR ( 50 ),
sex VARCHAR ( 20 ) 
)

2、执行结果

二、环境搭建

1、创建Maven项目

第一步：选择Maven下webapp项目

第二步：设置项目名和存储地址

第三步：对Maven进行相关设置（自动）

2、在pom.xml中添加相应坐标（版本可根据需要调整）

3、创建相关文件夹

三、创建相关文件

1、User实体类

package com.zibo.domain;

import java.io.Serializable;

public class User implements Serializable {
    private Integer id;
    private String username;
    private String password;
    private String sex;
    private int age;
    private String email;

    public Integer getId() {
        return id;
    }

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

    public String getUsername() {
        return username;
    }

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

    public String getPassword() {
        return password;
    }

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

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", username='" + username + '\'' +
                ", password='" + password + '\'' +
                ", sex='" + sex + '\'' +
                ", age=" + age +
                ", email='" + email + '\'' +
                '}';
    }
}

2、持久层IUserDao接口

package com.zibo.dao;

import com.zibo.domain.User;
import org.apache.ibatis.annotations.Select;
import org.apache.ibatis.annotations.Update;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository("userDao")
public interface IUserDao {
    //查询用户列表
    @Select("select * from user")
    List<User> findAll();
    //通过id查询
    @Select("select * from user where id = #{id}")
    User findById(Integer id);
    //更新user
    @Update("update user set username=#{username},password=#{password},age=#{age},sex=#{sex},email=#{email} where id=#{id}")
    void updateUser(User user);
}

3、业务层IUserService接口

package com.zibo.service;

import com.zibo.domain.User;

import java.util.List;

public interface IUserService {
    //查询用户列表
    List<User> findAll();
    //通过id查询
    User findById(Integer id);
    //更新user
    void updateUser(User user);
}

4、业务层IUserService接口实现类UserServiceImpl类

package com.zibo.service.impl;

import com.zibo.dao.IUserDao;
import com.zibo.domain.User;
import com.zibo.service.IUserService;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;
import java.util.List;

@Service("userService")
public class UserServiceImpl implements IUserService {

    @Resource(name = "userDao")
    private IUserDao userDao;

    @Override
    public List<User> findAll() {
        return userDao.findAll();
    }

    @Override
    public User findById(Integer id) {
        return userDao.findById(id);
    }

    @Override
    public void updateUser(User user) {
        userDao.updateUser(user);
    }
}

四、导入Spring配置文件并测试

1、导入Spring配置文件

applicationContext.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="
       http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd
       http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
    <!-- 配置 spring 创建容器时要扫描的包 -->
    <context:component-scan base-package="com.zibo">
        <!--制定扫包规则，不扫描@Controller 注解的 JAVA 类，其他的还是要扫描 -->
        <context:exclude-filter type="annotation"
                                expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
    <!-- 加载配置文件 -->
    <context:property-placeholder location="classpath:db.properties"/>
    <!-- 配置 MyBatis 的 Session 工厂 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 数据库连接池 -->
        <property name="dataSource" ref="dataSource"/>
    </bean>
    <!-- 配置数据源 -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.driver}"/>
        <property name="jdbcUrl" value="${jdbc.url}"/>
        <property name="user" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>
    <!-- 配置 Mapper 扫描器 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.itheima.dao"/>
    </bean>
    <tx:annotation-driven/>
    <!-- 配置事务管理器 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>
    <!-- 配置事务的通知 -->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
    	<tx:attributes>
    		<tx:method name="*" propagation="REQUIRED" read-only="false"/>
    		<tx:method name="find*" propagation="SUPPORTS" read-only="true"/>
    	</tx:attributes>
    </tx:advice>
    <!-- 配置aop -->
    <aop:config>
    	<aop:pointcut expression="execution(* com.itheima.service.impl.*.*(..))" id="pt1"/>
    	<aop:advisor advice-ref="txAdvice" pointcut-ref="pt1"/>
    </aop:config>
</beans>

db.properties：

jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/vuejsdemo
jdbc.username=root
jdbc.password=root

2、测试

测试前添加默认数据：

INSERT INTO `user` VALUES ('1', '33', '张老师', '123', 'zzz@itcast.cn', '男 ');
INSERT INTO `user` VALUES ('2', '31', '刘老师', '123', 'lll@itcast.cn', '女');
INSERT INTO `user` VALUES ('3', '17', '赵工', '213', 'zg@itcast.cn', '女');
INSERT INTO `user` VALUES ('4', '40', '高管', '213', 'gg@itcast.cn', 'female');
INSERT INTO `user` VALUES ('5', '28', '李总', '312', 'lz@jxjt.com', 'male');
INSERT INTO `user` VALUES ('6', '34', '王董', '312', 'wd@jxjt.com', 'male');
INSERT INTO `user` VALUES ('7', '55', '孙老板', '4321', 'slb@xzjt.com', '男');
INSERT INTO `user` VALUES ('8', '19', '陈秘书', '4321', 'cms@xzjt.com', '女');

编写测试类：

package com.zibo.user;

import com.zibo.domain.User;
import com.zibo.service.IUserService;
import com.zibo.service.impl.UserServiceImpl;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import javax.annotation.Resource;
import java.util.List;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:applicationContext.xml")
public class UserTest {
    @Resource(name = "userService")
    private IUserService userService;

    @Test
    public void testFindAll(){
        List<User> users = userService.findAll();
        System.out.println(users);
    }

    @Test
    public void testFindById(){
        User user = userService.findById(1);
        System.out.println(user);
    }

    @Test
    public void testUpdateUser(){
        User user = userService.findById(1);
        System.out.println("修改前的user：" + user);
        user.setAge(100);
        userService.updateUser(user);
        user = userService.findById(1);
        System.out.println("修改后的user：" + user);
    }
}

测试结果：

五、导入Spring MVC配置并编写控制器类

1、导入Spring MVC配置

第一步：导入页面文件

百度云下载地址：链接：https://pan.baidu.com/s/1m0aF5kzHlIN08EYfKnjnNg 提取码：zibo

第二步：配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">
  <display-name></display-name>

  <!-- 手动指定 spring 配置文件位置 -->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>
  <!-- 配置 spring 提供的监听器，用于启动服务时加载容器 。该间监听器只能加载 WEB-INF 目录中名称为 applicationContext.xml 的配置文件 -->
  <listener>
    <listener-class>
      org.springframework.web.context.ContextLoaderListener
    </listener-class>
  </listener>
  <!-- 配置 spring mvc 的核心控制器 -->
  <servlet>
    <servlet-name>springmvcDispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!-- 配置初始化参数，用于读取 spring mvc 的配置文件 -->
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring-mvc.xml</param-value>
    </init-param>
    <!-- 配置 servlet 的对象的创建时间点：应用加载时创建。取值只能是非 0 正整数，表示启动顺 序 -->
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>springmvcDispatcherServlet</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>
  <!-- 配置 springMVC 编码过滤器 -->
  <filter>
    <filter-name>CharacterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <!-- 设置过滤器中的属性值 -->
    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>
    </init-param>
    <!-- 启动过滤器 -->
    <init-param>
      <param-name>forceEncoding</param-name>
      <param-value>true</param-value>
    </init-param>
  </filter>
  <!-- 过滤所有请求 -->
  <filter-mapping>
    <filter-name>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
</web-app>

第三步：在resources中添加spring-mvc.xml配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">
    <!-- 配置创建 spring 容器要扫描的包 -->
    <context:component-scan base-package="com.zibo">
        <!-- 制定扫包规则 ,只扫描使用@Controller 注解的 JAVA 类 -->
        <context:include-filter type="annotation"
                                expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
    <mvc:annotation-driven />
</beans>

遇到问题，研究很久，还是被卡死了。。。难受，暂且搁置！
