idea spring+springmvc+mybatis環境配置整合詳解

1.打開idea，創建maven項目，File-New-Project 

2.選擇Maven，勾選Create from archetype,選擇org.apache.cocoon:cocoon-22-archetype-webapp,然後點擊Next 

3.填寫Groupid和Artifactid點擊Next 

4.選擇自己本地安裝的maven 

5.填寫項目名創建項目完成 

6.打開pom.xml加入壞境所需的依賴

7.添加Java目錄 
 
 

 
 

8.添加需要的包 
 
 
9.建立資源文件

9.增加必要主要類 
 
UserMapper

package com.cjq.dao;

import com.cjq.model.User;

import java.util.List;

/**
 * Created by struggle on 2017/7/26.
 */
public interface UserMapper {

    List<User> getAll();

    void save(User user);

    void delete(int id);

    void update(User user);

    User getUserById(int id);

}

UserMapper.xml

<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.cjq.dao.UserMapper">
    <!--目的:爲dao接口方法提供sql語句配置
    即針對dao接口中的方法編寫我們的sql語句-->

    <select id="getAll" resultType="com.cjq.model.User">
        select * from user
    </select>
    <select id="getUserById" resultType="com.cjq.model.User" parameterType="int">
        select * from user where id=#{id}
    </select>
    <insert id="save" parameterType="com.cjq.model.User">
        insert into user(id,name,age,password) values(#{id},#{name},#{age},#{password})
    </insert>
    <delete id="delete" parameterType="int">
        delete from user where id=#{id}
    </delete>
    <update id="update" parameterType="com.cjq.model.User">
        update user set name=#{name},age=#{age},password=#{password} where id=#{id}
    </update>
</mapper>

UserService

package com.cjq.service;

import com.cjq.model.User;
import org.springframework.transaction.annotation.Transactional;

import java.util.List;

/**
 * Created by struggle on 2017/7/26.
 */
@Transactional
public interface UserService {

    List<User> getAll();

    void save(User user);

    void delete(int id);

    void update(User user);

    User getUserById(int id);
}

UserServiceImpl

package com.cjq.service.impl;

import com.cjq.dao.UserMapper;
import com.cjq.model.User;
import com.cjq.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

/**
 * Created by struggle on 2017/7/26.
 */
@Service("userService")
public class UserServiceImpl implements UserService {

    @Autowired
    UserMapper userMapper;
    public List<User> getAll() {
        return userMapper.getAll();
    }

    public void save(User user) {
       userMapper.save(user);
    }

    public void delete(int id) {
      userMapper.delete(id);
    }

    public void update(User user) {
     userMapper.update(user);
    }

    public User getUserById(int id) {
        return userMapper.getUserById(id);
    }
}

10.使用Spring-test 測試 
UserServiceImplTest

package com.cjq.servoce.impl;

import com.cjq.model.User;
import com.cjq.service.UserService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import javax.annotation.Resource;
import java.util.Date;
import java.util.List;

/**
 * Created by struggle on 2017/7/26.
 */

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:spring/spring-*.xml")
public class UserServiceImplTest {
    @Resource
    Date date;
    @Resource
    UserService userService;

    @Test
    public void testDate(){
        System.out.println(date);
    }
    @Test
    public void testGetAll(){
        List<User> list=userService.getAll();
        for(User user:list){
            System.out.println(user.getName());
        }
    }
    @Test
    public void testGetUserById(){
        System.out.println(userService.getUserById(1).getName());
    }
    @Test
    public void testSave(){
        User user=new User();
        user.setName("test");
        user.setAge(11);
        user.setPassword("pass");
        userService.save(user);
    }
    @Test
    public void testDelete(){
        userService.delete(1);
    }
    @Test
    public void testUpdate(){
        User user=userService.getUserById(2);
        user.setName("hello");
        userService.update(user);
    }
}
