</dependency>在pojo包中新建Account实体类
在mapper包中新建AccountMapper接口
在resources中建立AccountMapper.xml映射文件，路径与AccountMapper相同
约束头
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="全限定名mapper类"></mapper>在resources引入德鲁伊连接池配置文件druid.properties
jdbc.driverClassName=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/db2?serverTimezone=UTC&characterEncoding=utf8&useUnicode=true&useSSL=false
jdbc.username=root
jdbc.password=123456
initialSize=5
maxActive=10
maxWait=3000在resources中建立spring核心配置文件applicationContext.xml
主要是管理service层，整合了mybatis核心文件
<?xml version="1.0" encoding="UTF-8"?>

<!--实现静态资源映射-->
<mvc:default-servlet-handler/>
</beans>新建service层接口AccountService
新建AccountServiceImp实现类，实现AccountService接口
新建AccountController类
在web.xml中加入
<!--前端控制器-->

编辑测试类，出现运行成果为成功
部署tomcat
注意：在没有前端页面的情况下报出404是正确的，前面测试成功，即为后端ssm框架搭建成功
