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);具体参照 https://blog.csdn.net/weixin_37139197/article/details/82975594 源代码 下载地址 https://www.lanzous.com/i3d5vgd
