maven+springMVC+mybatis+junit详细搭建过程（三）

6.  mybatis配置

   conf/mybatis-config.xml(mybatis配置的基本文件)

01	<?xml version="1.0" encoding="UTF-8" ?>

02	<!DOCTYPE configuration

03	PUBLIC "-//mybatis.org//DTD Config 3.0//EN"

04	"http://mybatis.org/dtd/mybatis-3-config.dtd">

05	<configuration>

06	<!-- 命名空间 -->

07	<typeAliases>

08	<typeAlias alias="User"type="cn.springmvc.model.User"/>

09	</typeAliases>

10

11	<!-- 映射map -->

12

<mappers>

13	</mappers>

14	</configuration>

mapper/UserMapper.xml(mybatis的实现)

01	<?xml version="1.0" encoding="UTF-8" ?>

02	<!DOCTYPE mapper

03	PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"

04	"http://mybatis.org/dtd/mybatis-3-mapper.dtd">

05	<mapper namespace="cn.springmvc.dao.UserDAO">

06

07	<insert id="insertUser" parameterType="User" keyProperty="id">

08	insert into days_user(

09

state,

10

nickname)

11

values

12

(

13

#{state},

14	#{nickname})

15

</insert>

16

17

</mapper>

这样就完成了基本插入用户的功能！

7.  junit测试插入功能

cn.springmvc.test/UserTest.java(用户测试模块)

01	package cn.springmvc.test;

02

03	import org.junit.Before;

04	import org.junit.Test;

05	import org.springframework.context.ApplicationContext;

06	import org.springframework.context.support.ClassPathXmlApplicationContext;

07

08	import cn.springmvc.model.User;

09	import cn.springmvc.service.UserService;

10

11

12

13	public class UserTest {

14

15	private UserService userService;

16

17

@Before

18	public voidbefore(){

19	@SuppressWarnings("resource")

20	ApplicationContext context = new ClassPathXmlApplicationContext(newString[]{"classpath:conf/spring.xml"

21	,"classpath:conf/spring-mybatis.xml"});

22	userService = (UserService) context.getBean("userServiceImpl");

23

}

24

25

@Test

26	public void addUser(){

27	User user = new User();

28	user.setNickname("你好");

29	user.setState(2);

30	System.out.println(userService.insertUser(user));

31

}

32

}

测试结果如图：

即完成插入功能！

8.  springMVC模块搭建 

    web.xml（web功能配置）
