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")

接下来是我的项目结构截图

然后是service 的截图，我在这里加了注解@Service

最后我在测试类里面 的截图

最后附上我的maven的pom 我开始怀疑是这个配置的有问题了
