如何在AspectJ中的AfterThrowing中吞下异常 [英] How to swallow a exception at AfterThrowing in AspectJ

问题描述

在AspectJ中，我想吞下一个异常.

In AspectJ, I want to swallow a exception.

@Aspect
public class TestAspect {

 @Pointcut("execution(public * *Throwable(..))")
 void throwableMethod() {}

 @AfterThrowing(pointcut = "throwableMethod()", throwing = "e")
 public void swallowThrowable(Throwable e) throws Exception {
  logger.debug(e.toString());
 }
}

public class TestClass {

 public void testThrowable() {
  throw new Exception();
 }
}

上面，它没有吞下异常. testThrowable()的调用方仍然收到异常.我希望呼叫者不接收异常.怎么办呢? 谢谢.

Above, it didn't swallow exception. The testThrowable()'s caller still received the exception. I want caller not to receive exception. How can do this? Thanks.

推荐答案

我认为不能在AfterThrowing中完成.您需要使用Around.

I think it can't be done in AfterThrowing. You need to use Around.
