【已解决】Spring下启动工程报错{@org.springframework.beans.factory.annotation.Autowired(required=true)}

夭寿啦，在启动Spring工程的时候，控制台报错
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘fm.douban.app.AppApplication’: Unsatisfied dependency expressed through field ‘songListControl’; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type ‘fm.douban.app.control.SongListControl’ available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

这个报错是注入失败，spring的bean没有扫描到完整的内容，检查了一下代码，发现是实现类的@Serice注解缺失没有加上

把@Service注解加上，再次启动就没有报错了，试了一下相关的注解，不管是实现类的@Service注解，还是控制类里面的@Controller和@Autowired注解缺失，都会出现这个bean扫描不完整的报错
