I had a similar issue with Spring boot and @ComponentScan and this document helped me solving the issue: http://docs.spring.io/spring-boot/docs/current/reference/html/using-boot-structuring-your-code.html.
我在 Spring boot 和 @ComponentScan 上遇到了类似的问题，这个文档帮助我解决了这个问题：http: //docs.spring.io/spring-boot/docs/current/reference/html/using-boot-structuring-your-代码.html。
The point was that my @SpringBootApplicationclass was in the root package of one of basePackages of @ComponentScan. After I moved it to a subpackage, Spring was able to recognize all @ComponentScans.
关键是我的@SpringBootApplication课程位于 .basePackages 之一的根包中@ComponentScan。在我把它移到一个子包之后，Spring 能够识别所有的@ComponentScans。
