我也遇到过这个问题，并通过删除Spring Facet来解决它:

File ->项目结构 选择方面 拆卸弹簧

好运！

IntelliJ IDEA Ultimate

将您的主类添加到IntelliJ Spring应用程序上下文中，例如Application.java

文件->项目结构..

左边: 项目设置->模块

右边:在你的包结构中找到 Spring并添加+ Application.java

在bean配置文件中放置@Component或@configuration似乎可以工作，例如:

@Configuration
public class MyApplicationContext {
    @Bean
    public DirectoryScanner scanner() {
        return new WatchServiceDirectoryScanner("/tmp/myDir");
    }
}

@Component
public class MyApplicationContext {
    @Bean
    public DirectoryScanner scanner() {
        return new WatchServiceDirectoryScanner("/tmp/myDir");
    }
}

@Autowired(required = false) 能让intellij闭嘴吗

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

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。)
