至于intelliJ 2021.2.3版(终极版)，我把“spring bean组件中不正确的注入点自动装配”改为警告，这对我来说很有用

我有同样的问题，并解决了它使用“Invalidate Caches…”在文件菜单下。

我的IntelliJ IDEA Ultimate版本(2016.3.4 Build 163)似乎支持这一点。诀窍在于您需要启用Spring Data插件。

I had similar issue in Spring Boot application. The application utilizes Feign (HTTP client synthetizing requests from annotated interfaces). Having interface SomeClient annotated with @FeignClient, Feign generates runtime proxy class implementing this interface. When some Spring component tries to autowire bean of type SomeClient, Idea complains no bean of type SomeClient found since no real class actually exists in project and Idea is not taught to understand @FeignClient annotation in any way.

解决方案:用@Component注解接口SomeClient。(在我们的例子中，我们没有直接在SomeClient上使用@FeignClient注释，而是使用metaannotation @OurProjectFeignClient，它是带注释的@FeignClient，并向其添加@Component注释也可以工作。)

我只能使用@EnableAutoConfiguration来解决它，但是这个错误没有功能上的影响。

检查bean的包是否正确编写

//Check if this is written right 
package com.package1.package2.package3


import ...

@Service
class ServiceX {

  ...

}
