在Spring Boot中,是否可以为Interface添加@Service注解?如果该接口未被任何 class 实现

In Spring Boot, Can we add @Service Annotation for Interface? if that interface is not implemented by any class

我创建了一个没有任何实现的接口

@Service
public interface MyInterface{


    default void doSomething{
      System.out.print("print something");
    }
}

MyInterface 可以用@Autowired 注解吗?

@Autowired
MyInterface myInterFace;

运行

时显示以下错误
***************************
APPLICATION FAILED TO START
***************************

Description:

Field myInterFace in com.example.demo.controller.corejava.CoreJavaController required a bean of type 'com.example.demo.controller.corejava.MyInterface' that could not be found.

The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)

不,你不能,因为 Spring 试图实例化它来创建一个 Bean (@Service),但它是一个接口,所以那是不可能的。
