spring+mybatis整合

前言

前面写了mybatis的数据库文件生成java文件和xml配置文件，现在开始最重要的spring+mybatis配置，以前没有人讲到每个jar拿做什么我就说说吧，因为不要乱加jar！！！烦

一、pom文件引入，具体介绍每个包的用途。没有一个多余jar，很难得哦！

二、进行整合测试

         首先当然是写实现类的接口

1、Userservice接口编写

package com.ycy.service;

import com.ycy.model.UserAccount;

/**
 * Created by Administrator on 2015/8/13 0013.
 */
public interface Userservice {
    public UserAccount getUserAccountById(Long userId);
}
2、UserserviceImpl编写

注意提示：

package com.ycy.service.impl;

import com.ycy.dao.UserAccountMapper;
import com.ycy.model.UserAccount;
import com.ycy.service.Userservice;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

/**
 * Created by Administrator on 2015/8/13 0013.
 */
@Service
public class UserserviceImpl implements Userservice {
    @Autowired
    private UserAccountMapper userAccountMapper;


    public UserAccount getUserAccountById(Long userId) {

        return userAccountMapper.selectByPrimaryKey(userId);
    }
}

3、编写测试类TestMybatis 

package com;

import com.ycy.model.UserAccount;
import com.ycy.service.Userservice;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

/**
 * Created by Administrator on 2015/8/13 0013.
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath*:spring/applicationContext.xml","classpath*:spring/spring-mybatis.xml"})
public class TestMybatis {
 @Autowired
 private  Userservice userservice;
    @Test
    public  void  test1(){
       UserAccount u= userservice.getUserAccountById(1l);
        System.out.println(u.getName());
    }

}


最终测试结果：

重要提示：idea与Eclipse不同，它不能读取src下面java的里面的xml，一般你放到resources的文件夹里面classpath:是个读取到的，

否则需要如下配置（一般不建议啊）直接在bulid里面：

  <build>
        <finalName>YiTang</finalName>
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*Mapper.xml</include>
                </includes>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.xml</include>
                    <include>**/*.properties</include>
                </includes>
            </resource>
        </resources>
    </build>

到此mybatis与spring整合完毕，测试完毕。下一步整合mvc。。。。。主要 的
