解决异常：org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name

报错信息：
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘receiverController’: Unsatisfied dependency expressed through field ‘service’; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type ‘com.teemlink.sync.service.SyncService’ available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:586)

2、检查receiverController类调用的service类有没有添加@Service注解

3、检查receiverController类下的Dao层或Mapper层类上有没有添加注解

4、检查启动类上包扫描有没有扫描到receiverController类
