AspectJ指向特定方法中的方法调用的切入点 [英] AspectJ pointcut to method call in specific methods

问题描述

我想创建一个切入点，以将特定方法的调用作为目标.

采取以下措施:

class Parent {
   public foo() {
     //do something
   }
}

class Child extends Parent {
   public bar1() {
     foo();
   }
   public bar2() {
     foo();
   }
   public bar3() {
     foo();
   }
}

我想在方法bar1()和bar3()中对foo()的调用切入点

我在想类似的东西

pointcut fooOperation(): call(public void Parent.foo() && (execution(* Child.bar1()) || execution(* Child.bar3()) );

before() : fooOperation() {
  //do something else
}

但是，这似乎不起作用.有什么想法吗?

谢谢

解决方案

也许withincode可以工作:

call(public void Parent.foo()) && (withincode(* Child.bar1()) || withincode(* Child.bar3()) );

或者，您可以尝试cflow切入点:

pointcut bar1(): call(* Child.bar1());
pointcut bar3(): call(* Child.bar3());

call(public void Parent.foo()) && (cflow(bar1()) || cflow(bar3());

在此处查找切入点参考

I want to create a pointcut to target a call to a method from specific methods.

take the following:

class Parent {
   public foo() {
     //do something
   }
}

class Child extends Parent {
   public bar1() {
     foo();
   }
   public bar2() {
     foo();
   }
   public bar3() {
     foo();
   }
}

I would like to have a point cut on the call to foo() in methods bar1() and bar3()

I was thinking something like

pointcut fooOperation(): call(public void Parent.foo() && (execution(* Child.bar1()) || execution(* Child.bar3()) );

before() : fooOperation() {
  //do something else
}

however, that doesnt seem to work. any ideas?

thanks

解决方案

Maybe withincode will work:

call(public void Parent.foo()) && (withincode(* Child.bar1()) || withincode(* Child.bar3()) );

Alternatively you could try the cflow pointcut:

pointcut bar1(): call(* Child.bar1());
pointcut bar3(): call(* Child.bar3());

call(public void Parent.foo()) && (cflow(bar1()) || cflow(bar3());

Look here for a pointcut reference
