抽象超类中实现的超级接口方法的方面 [英] Aspect on super interface method implemented in abstract super class

问题描述

我有一个非常类似于的问题:如何在从超级"继承的接口方法上创建方面接口，但是我的save方法在抽象超类中.

I have a problem quite similar to: How to create an aspect on an Interface Method that extends from A "Super" Interface, but my save method is in an abstract super class.

结构如下-

接口:

public interface SuperServiceInterface {
    ReturnObj save(ParamObj);
}

public interface ServiceInterface extends SuperServiceInterface {
    ...
}

实施:

public abstract class SuperServiceImpl implements SuperServiceInterface {
    public ReturnObj save(ParamObj) {
        ...
    }
}

public class ServiceImpl implements ServiceInterface extends SuperServiceImpl {
    ...
}

我想检查对ServiceInterface.save方法的所有调用.

I want to inspect any calls made to the ServiceInterface.save method.

我当前拥有的切入点是这样的:

The pointcut I have currently looks like this:

@Around("within(com.xyz.api.ServiceInterface+) && execution(* save(..))")
public Object pointCut(final ProceedingJoinPoint call) throws Throwable {
}

将save方法放入ServiceImpl时将触发该事件，但将其保存在SuperServiceImpl中时则不会触发该事件. 我的切入点缺少什么?

It gets triggered when the save method is put into the ServiceImpl, but not when it is in the SuperServiceImpl. What am I missing in my around pointcut?

推荐答案

我只想在ServiceInterface上进行切入点，如果我在SuperServiceInterface上进行切入，是否也可以在同样继承自SuperServiceInterface的接口上拦截保存调用?

I just want to pointcut on the ServiceInterface, if I do it on SuperServiceInterface wouldn't it also intercept save calls on interfaces that also inherit from SuperServiceInterface?

是的，但是可以通过如下方式将target()类型限制为ServiceInterface来避免这种情况:

Yes, but you can avoid that by restricting the target() type to ServiceInterface as follows:

@Around("execution(* save(..)) && target(serviceInterface)")
public Object pointCut(ProceedingJoinPoint thisJoinPoint, ServiceInterface serviceInterface)
    throws Throwable
{
    System.out.println(thisJoinPoint);
    return thisJoinPoint.proceed();
}
