SSM 文件以及大部分参考博客 https://blog.****.net/qq598535550/article/details/51703190

简答的登陆注册案例下载链接在末尾补贴图了

测试基类 测试的时候继承这个类 加个@Test就行

package test;

import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; @RunWith(SpringJUnit4ClassRunner.class)
// 告诉junit spring配置文件
@ContextConfiguration({ "classpath:spring/spring-dao.xml", "classpath:spring/spring-service.xml" })
public class BaseTest {
}

遇到的问题(刚学也没系统的看教程)

1 里面配置不太清楚 准备日后理解 这是一个模板

2 三层关系要搞清楚

JAVAEE 开发三层

Controller 和页面进行数据交互
Service Controller 调用Service ,进行业务逻辑操作 Service 调用mapper 查询数据操作
mapper ,dao 和数据库进行数据交hu

3 进行  数据库参数大于1 的操作时要加 @parm

例如

boolean insertUser(@Param("username")String username, @Param("password")String password);
