Junit测试 - Spring的配置

第一种：

@ContextConfiguration(locations = {"classpath*:/spring-core.xml"})
public class UserMapperTest extends AbstractJUnit4SpringContextTests {

    @Resource
    private UserMapper userMapper;

    @Test
    public void testQueryAllUser () {
        User user = userMapper.queryById("1");

        System.out.println(user.getName());
    }
}

第二种：

public class UserMapperTest2 {

    private UserMapper userMapper;

    @Before
    public void init(){
        ApplicationContext ctx = new FileSystemXmlApplicationContext("classpath*:/spring/applicationContext.xml");
        userMapper = (UserMapper)ctx.getBean("userMapper");
    }

    public UserMapper getUserMapper() {
        return userMapper;
    }

    public void setUserMapper(UserMapper userMapper) {
        this.userMapper = userMapper;
    }

}

UserMapper需要加注解：

/**
 * 用户信息数据持久化操作接口
 */
@Repository
public interface UserMapper extends BaseMapper<User>
