你可 以使用 sqlSessionFactoryBeanName 或 sqlSessionTemplateBeanName 属性来设置正确的 bean 名 称来使用。这就是它如何来配置的,注意 bean 的名称是必须的,而不是 bean 的引用,因 此,value 属性在这里替代通常的 ref:

4.实体类
package com.tliu.case2.domain;
import java.io.Serializable;
import java.util.Date;
public class User implements Serializable{
private static final long serialVersionUID = 4714695050355640732L;
private String userid;
private String username;
private String nickname;
private String password;
private Date createDate = new Date();
public String getPassword() {
return password;
}

}
}
5.UserMapper接口 & UserMapper.xml
package com.tliu.case2.mapper;
import java.util.List;
import org.springframework.stereotype.Repository;
import com.tliu.case2.domain.User;
@Repository
public interface UserMapper {

}
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"

6.UserService & UserServiceImpl
package com.tliu.case2.service;
import java.util.List;
import com.tliu.case2.domain.User;
public interface UserService {
int addUser(User user);
List<User> findList();
}
package com.tliu.case2.service.impl;
import java.util.List;
import javax.inject.Inject;
import org.springframework.stereotype.Service;
import com.tliu.case2.domain.User;
import com.tliu.case2.mapper.UserMapper;
import com.tliu.case2.service.UserService;
@Service("userService")
public class UserServiceImpl implements UserService{
@Inject
private UserMapper userMapper;
public int addUser(User user) {
return userMapper.addUser(user);
}
@Override
public List<User> findList() {
return userMapper.findList();
}
}
7.编写测试代码
package com.tliu.case2.service;
import java.util.List;
import java.util.UUID;
import javax.inject.Inject;
import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;

import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import com.tliu.case2.domain.User;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("/beans.xml")
public class MainTest {
@Inject
private UserService userService;
@Test
public void init(){
Assert.assertNotNull(userService);
}
@Test
public void testAdd(){
User user = new User();
user.setNickname("Jack");
user.setPassword("123456");
user.setUsername("Jack-OK");
user.setUserid(UUID.randomUUID().toString());
userService.addUser(user);
}
@Test
public void testFindUsers(){
List<User> users = userService.findList();
Assert.assertNotNull(users);
}
}
