springboot 报错 org.springframework.beans.factory.NoSuchBeanDefinitionException:No qualifying bean of type 'com.example.service.HrService' available: 有没有大佬出个主意,我找了一天,刚入门springboot

话不多说先上图,这是启动类的配置,这里配置了@ComponentScan("我的mapper的接口")

springboot 报错  org.springframework.beans.factory.NoSuchBeanDefinitionException:No qualifying bean of type 'com.example.service.HrService' available:   有没有大佬出个主意,我找了一天,刚入门springboot

接下来是我的项目结构截图

springboot 报错  org.springframework.beans.factory.NoSuchBeanDefinitionException:No qualifying bean of type 'com.example.service.HrService' available:   有没有大佬出个主意,我找了一天,刚入门springboot

然后是service 的截图,我在这里加了注解@Service

springboot 报错  org.springframework.beans.factory.NoSuchBeanDefinitionException:No qualifying bean of type 'com.example.service.HrService' available:   有没有大佬出个主意,我找了一天,刚入门springboot

最后我在测试类里面 的截图

springboot 报错  org.springframework.beans.factory.NoSuchBeanDefinitionException:No qualifying bean of type 'com.example.service.HrService' available:   有没有大佬出个主意,我找了一天,刚入门springboot

最后附上我的maven的pom 我开始怀疑是这个配置的有问题了

详细的报错信息如下:

经过几位大佬的提醒,在启动类新增了@MapperScan("com.example.Mappar"),同时在测试类加入启动类@RunWith(SpringRunner.class) 解决了找不dao bean 的问题,但随后又产生了一个新的报错如下:

springboot 报错  org.springframework.beans.factory.NoSuchBeanDefinitionException:No qualifying bean of type 'com.example.service.HrService' available:   有没有大佬出个主意,我找了一天,刚入门springboot

与之对应的我的mapper.xml文件如下:

springboot 报错  org.springframework.beans.factory.NoSuchBeanDefinitionException:No qualifying bean of type 'com.example.service.HrService' available:   有没有大佬出个主意,我找了一天,刚入门springboot

我的mapper接口如下:

springboot 报错  org.springframework.beans.factory.NoSuchBeanDefinitionException:No qualifying bean of type 'com.example.service.HrService' available:   有没有大佬出个主意,我找了一天,刚入门springboot

最后我的HrService:

springboot 报错  org.springframework.beans.factory.NoSuchBeanDefinitionException:No qualifying bean of type 'com.example.service.HrService' available:   有没有大佬出个主意,我找了一天,刚入门springboot

详细报错如下:

springboot 报错  org.springframework.beans.factory.NoSuchBeanDefinitionException:No qualifying bean of type 'com.example.service.HrService' available:   有没有大佬出个主意,我找了一天,刚入门springboot

我在网上翻阅了资料:有的解决办法是看pom.xml里面的build 下 resouce 没有添加,我添加了后发现,还是无效。此外在namespace 和对应的service 里面,mapper 方法的名称都是一致,在torget目录下,我的HrMappar.class 和HrService.xml在同一目录下。很疑惑问题出在哪里了。
