Spring MVC集成MyBatis后做单元测试保证数据自动回滚
1、需求：
希望在对做MyBatis做单元测试的时候，新增、修改、删除可以一直可测试，这样在新增功能时，能够保证软件的质量随着功能的迭代而不至于下降。
2、项目目录
3、项目文件pom.xml
4、项目文件web.xml
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
id="WebApp_ID" version="2.5">
5、前端页面：index.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
Hello World!
${user.userId}
${user.userName}
${user.userPassword}
${user.userEmail}
6、单元测试目录：
7、单元测试文件：SpringTestCase.java
package com.lin.baseTest;
import org.junit.runner.RunWith;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests;
import org.springframework.test.context.junit4.AbstractTransactionalJUnit4SpringContextTests;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.transaction.TransactionConfiguration;
import org.springframework.transaction.annotation.Transactional;
/**
* 功能概要：
*
* @author linbingwen
* @since 2015年9月28日
*/
//指定bean注入的配置文件
@ContextConfiguration(locations = { "classpath:application.xml" })
//使用标准的JUnit @RunWith注释来告诉JUnit使用Spring TestRunner
@RunWith(SpringJUnit4ClassRunner.class)
/*添加事务回滚20180516*/
@Transactional
//@TransactionConfiguration(transactionManager = "transactionManager")
@TransactionConfiguration(transactionManager = "txManager", defaultRollback = true)
public abstract class SpringTestCase extends AbstractTransactionalJUnit4SpringContextTests //AbstractJUnit4SpringContextTests
{
protected Logger logger = LoggerFactory.getLogger(getClass());
}
8、单元测试文件：UserServiceTest.java
package com.lin.service;
import org.apache.log4j.Logger;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import com.lin.baseTest.SpringTestCase;
import com.lin.domain.User;
/**
* 功能概要：UserService单元测试
*
* @author linbingwen
* @since 2015年9月28日
*/
public class UserServiceTest extends SpringTestCase {
@Autowired
private UserService userService;
Logger logger = Logger.getLogger(UserServiceTest.class);
@Test
public void selectUserByIdTest(){
User user = userService.selectUserById(10);
logger.debug("查找结果" + user);
// logger.debug("查找结果" + "空测试方法！");
}
@Test
public void addUserTest(){
User user=new User();
// user.setUserEmail("email");
// user.setUserName("name");
// user.setUserPassword("password");
user.setUserEmail("boyzhaohy@vip.sina.com");
user.setUserName("Auroral");
user.setUserPassword("2319474666");
userService.addUser(user);
logger.debug("新增用户ID" + user.getUserId());
// logger.debug("查找结果" + "空测试方法！");
}
}

@Controller
public class UserController {
@Resource
private UserService userService;
@RequestMapping("/")
public ModelAndView getIndex(){
ModelAndView mav = new ModelAndView("index");
User user = userService.selectUserById(1);
mav.addObject("user", user);
return mav;
}
}
