Java Aspect返回要在方法中使用的值 [英] Java Aspect returned value to be used in the method

问题描述

我有一个运行某些逻辑的 @After java方面。我需要它来返回一个结果（一个对象），该结果可以在方面的切入点截获的方法中使用。可能吗？

I have an @After java aspect that runs certain logic. I need it to return a result (an object) that can be used in the methods intercepted by the aspect's pointcut. Is it possible?

推荐答案

您需要的是 @Around ，它允许您返回任何内容你想要建议的对象：

What you need is @Around which allows you to return whatever you want to the advised object:

@Around("com.xyz.myapp.UserService.createUser()")
public Object userCreationAdvice(ProceedingJoinPoint pjp) throws Throwable {
    //Do something if needed before method execution
    Object retVal = pjp.proceed();
    //Do something if needed after method execution
    return retVal;
}
