</project>

创建数据库

SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;

-- ----------------------------
-- Table structure for user
-- ----------------------------
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user`  (
  `id` int(11) NOT NULL AUTO_INCREMENT COMMENT '主键ID',
  `username` varchar(30) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '用户名',
  `password` varchar(30) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '密码',
  PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 2 CHARACTER SET = utf8 COLLATE = utf8_general_ci COMMENT = '用户表' ROW_FORMAT = Compact;

-- ----------------------------
-- Records of user
-- ----------------------------
INSERT INTO `user` VALUES (1, 'zs', '123');

SET FOREIGN_KEY_CHECKS = 1;

创建实体类User

package com.qbb.ssm.entity;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

/**

    <!--3.将SpringMVC不能处理的请求交给tomcat-->
    <mvc:default-servlet-handler/>

    <!--4.配置view-controller-->
    <mvc:view-controller path="/main.html" view-name="main"/>

    <!--5.开启SpringMVC注解驱动-->
    <mvc:annotation-driven/>

</beans>

修改web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">
    <!--1.启动Spring容器-->
    <!--加载Spring配置文件-->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:applicationContext.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!--2.配置SpringMVC前端控制器，拦截前端所有请求-->
    <servlet>
        <servlet-name>dispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-mvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>

    <servlet-mapping>
        <servlet-name>dispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>

    <!--3.字符编码过滤器,一定要放在所有过滤器之前-->
    <filter>
        <filter-name>characterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>

    <filter-mapping>
        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!--4.使用Rest风格的URI，将页面的post请求转为指定的delete或者put请求-->
    <filter>
        <filter-name>hiddenHttpMethodFilter</filter-name>
        <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>

        <filter-name>hiddenHttpMethodFilter</filter-name>

创建页面

<!DOCTYPE html>
<html lang="en">

    <meta charset="UTF-8">
    <title>用户列表</title>
</head>
<body>
<div id="app">

        <tr>
            <th>ID</th>
            <th>用户名</th>
            <th>密码</th>
        </tr>
        <tr v-for="(user,index) in userList" :key="user.id">
            <td v-text="user.id"></td>
            <td v-text="user.username"></td>
            <td v-text="user.password"></td>
        </tr>
    </table>
</div>
</body>
<script src="/ssm/js/vue.js"></script>
<script src="/ssm/js/axios.min.js"></script>
<script>
    new Vue({
        el: '#app',
        data: {
            userList: []
        },
        created() {
            this.findAll()
        },
        methods: {
            findAll() {
                console.log('aaa')
                axios({
                    url: '/ssm/user/findAll',
                    method: 'get'
                }).then(response => {
                    this.userList = response.data.data
                })
            }
        }
    })
</script>
</html>
