如何配置AspectJ忽略getter和setter [英] How to configure aspectj ignore getters and setters

问题描述

我目前有一个方面可以捕获包中所有公共方法的执行情况.

I have an aspect that currently works to capture all public method executions within my package.

我想对其进行修改，以同时排除设置方法和获取方法，所以我尝试了这些，这些是我尝试过的变体:

I would like to modify that to exclude both setters and getters, so I tried that and these are the variants I tried:

这是可行的，但是显然对设置方法或获取方法没有任何作用.

This one works, but does obviously does not do anything for setters or getters.

@Around("execution(public * *(..)) && !within(com.walterjwhite.logging..*)")

无法编译:

@Around("execution(public * *(..)) && !within(* set*(..))")

这可以编译，但不会阻止捕获设置器/获取器:

This compiles, but doesn't prevent capturing setters/getters:

@Around("execution(public * *(..)) && !execution(* set*(..))")

我也参考了这篇文章，但这没有用.尝试编译方面时出现编译错误.

I also came across this post as a reference, but that didn't work. I get compilation errors when trying to compile the aspect.

如何在AspectJ中排除吸气剂和吸气剂?

推荐答案

第二个不编译，因为within()需要类型签名，而不是方法签名.您所指的答案是完全错误的，我不知道为什么会接受.我只是写了一个新的来纠正该虚假信息.

The second one does not compile because within() needs a type signature, not a method signature. The answer you are referring to is just plain wrong, I have no idea why it was accepted. I just wrote a new one in order to correct that false information.

您的上一次尝试基本上是正确的，但仅忽略设置方法，而不忽略获取方法.试试这个:

Your last try is basically right, but only ignores setters, not getters. Try this:

驱动程序应用程序:

package de.scrum_master.app;

public class Application {
  private int id;
  private String name;

  public int getId() {
    return id;
  }
  public void setId(int id) {
    this.id = id;
  }
  public String getName() {
    return name;
  }

  public void setName(String name) {
    this.name = name;
  }

  public void doSomething() {
    System.out.println("Doing something");
  }

  public static void main(String[] args) {
    Application application = new Application();
    application.setId(11);
    application.setName("John Doe");
    application.doSomething();
    System.out.println(application.getId() + " - " + application.getName());
  }
}

方面:

package de.scrum_master.aspect;

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;

@Aspect
public class MyAspect {
  @Around("execution(public * *(..)) && !execution(void set*(*)) && !execution(!void get*())")
  public Object myAdvice(ProceedingJoinPoint thisJoinPoint) throws Throwable {
    System.out.println(thisJoinPoint);
    return thisJoinPoint.proceed();
  }
}

控制台日志:

execution(void de.scrum_master.app.Application.main(String[]))
execution(void de.scrum_master.app.Application.doSomething())
Doing something
11 - John Doe

请注意

• 如果您有类似isActive()这样的布尔值的吸气剂，并且还想忽略它们，则必须将切入点扩展&& !execution(boolean is*()).
带有名称模式的
• 这类切入点始终只是试探法，因此请提防方法名称，例如getaway，settleConflict，isolate.他们也将被忽略.

• if you have getters for boolean values like isActive() and also want to ignore them, you have to extend the pointcut by && !execution(boolean is*()).
• those kinds of pointcuts with name patterns are always just heuristics, so beware of method names such as getaway, settleConflict, isolate. They would also be ignored.
