測試基類 測試的時候繼承這個類 加個@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) // 告訴junit spring配置文件
@ContextConfiguration({ "classpath:spring/spring-dao.xml", "classpath:spring/spring-service.xml" }) public class BaseTest { }

 

 

遇到的問題（剛學也沒系統的看教程）

1 裏面配置不太清楚 準備往後理解 這是一個模板

2 三層關係要搞清楚

JAVAEE 開發三層

Controller 和頁面進行數據交互
Service Controller 調用Service ，進行業務邏輯操做 Service 調用mapper 查詢數據操做
mapper ，dao 和數據庫進行數據交hu

3 進行  數據庫參數大於1 的操做時要加 @parm 

例如

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