org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'seniorContro

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'seniorController': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.superr.powerful.progect.senior.service.SeniorService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

出现这样的错误，原因是bean没有注入进去，要把用到的service注入到spring的applicationcontext中，就可以了，当然还有其他的原因，具体情况具体分析
