我能想到的解决办法如下-

public interface IValidator {

   public Service getBeanToBeAutowired();

   default Boolean doSomeNewValidations(){
    return getBeanToBeAutowired().doSomeNewValidations();
   }

}

public class ValidatorClass implements IValidator {

    @Autowire private Service service;

    @Override
    public Service getBeanToBeAutowired() {
        return service;
    }

}

在Java中不可能在接口中添加变量。默认情况下，它将是public static final常量。因此您必须执行以下操作之一：

MyValidationBean beanToBeAutowired = new MyValidationBeanImpl();

或以下内容：

MyValidationBean beanToBeAutowired();

default Boolean doSomeNewValidations(){
    return beanToBeAutowired().doSomeNewValidations();
}

您可以在实现类中重写beanToBeAutowired方法。

只是一个想法，发送验证bean到接口为parameter;

public interface IValidator {

    default Boolean doSomeNewValidations(MyValidationBean beanToBeAutowired){
        return beanToBeAutowired.doSomeNewValidations();
    }
}

您的callerClass;

public class CallerClass implements IValidator{

    @Autowired
    MyValidationBean beanToBeAutowired;
    ...

    doSomeNewValidations(beanToBeAutowired);

}
