遇到Invalid bound statement (not found)踩的坑

代码

@RunWith(SpringRunner.class)
@SpringBootTest
public class MybatisTest {
    @Autowired
    private DataSource dataSource;
    @Autowired
    private MemberPOMapper memberPOMapper;

    private Logger log=LoggerFactory.getLogger(MybatisTest.class);
    @Test
    public void testMapper(){
        BCryptPasswordEncoder passwordEncoder = new BCryptPasswordEncoder();
        String source="123123";
        String encode = passwordEncoder.encode(source);
        MemberPO memberPO = new MemberPO(null, "jack", encode,
                "杰克", "jack@qq.com", 1, 1, "杰克",
                "123123", 2);
        memberPOMapper.insert(memberPO);

    }
    }

遇到的问题

org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.atguigu.crowd.mapper.MemberPOMapper.insert

看了一下我的application.yml是没有问题的

server:
  port: 2000
spring:
  application:
    name: atguigu-crowd-mysql
  datasource:
    name: mydb
    type: com.alibaba.druid.pool.DruidDataSource
    url: jdbc:mysql://127.0.0.1:3306/project_crowd?serverTimezone=UTC
    username: root
    password: 123456
    driver-class-name: com.mysql.cj.jdbc.Driver
eureka:
  client:
    service-url:
      defaultZone: http://localhost:1000/eureka
mybatis:
  mapper-locations: classpath*:/mybatis/mapper/*Mapper.xml
logging:
  level:
    com.atguigu.crowd.mapper: debug
    com.atguigu.crowd.test: debug

原因

排查后发现xml并没有像接口那样按照文件层级编译，而是被当做了一个文件夹名为mybatis.mapper的文件夹处理。

操作

重新建mybatis包和mapper包，记住要分开建包，然后删除之前的target，重新运行，然后就成功了。

结果
