unit-testing - 在 Springboot 中测试 mybatis 功能时如何修复“ibatis 绑定异常”？

问题描述

我正在尝试在 SpringBoot 中对 Mybatis 进行单元测试。每当我尝试执行 mapper.xml 中定义的查询时，我都会收到 ibatis.binding.bindingException。

我的测试代码存储在 src/test/java/service 中，名称为 UserServiceImplTest。

@SpringBootTest
@RunWith(SpringRunner.class)
public class UserServiceImplTest {


    @Autowired
    UserDao userDao;

    @Test
    public void getUserByIdAndEmail() throws SQLException {
        User user = userDao.getUserByIdAndEmail("admin", "admin@sample.com");
        assertThat(user.getUser_email()).isEqualTo("admin@sample.com");
    }
}

@Repository
public class UserDao implements UserDaoMapper{  
    @Autowired  
    private SqlSessionTemplate sqlSession;

    public User getUserByIdAndEmail(String user_id, String user_email) {
        UserDaoMapper mapper = sqlSession.getMapper(UserDaoMapper.class);
        return mapper.getUserByIdAndEmail(user_id, user_email);
    }   
}

SqlSessionTemplate、SqlSessionFactory 和 Datasource bean 定义在一个有 @SpringBootApplication 的 java 文件中。

从

User user = userDao.getUserByIdAndEmail("admin", "admin@sample.com");

我希望至少获得空用户，但是在执行方法本身时会弹出错误。下面是错误日志。

解决方案

由于某种原因，在测试中创建一个'resources'目录并移动资源下的*mapper.xml文件后直接解决了这个问题。我猜测试类找不到 mapper.xml 文件，导致绑定异常。
