小编use*_*705的帖子

我是AOP的新手.我有这样的问题.

package org.suman.Aspect;

import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;

@Aspect
public class LoginAspect {
    //@Before("execution(public String getName())")
    //@Before("execution(public String org.suman.Model.Triangle.getName())")
    //@Before("execution(* get*())")
    //@Before("execution(* get*(..))")
    //@Before("execution(* org.suman.Model.*.get*())")

    //@Before("execution(* get*())&& within(org.suman.Model.Circle)")
    @Before("execution(* get*())&& allCircle()")
    //@Before("allGetters() && allCircle()")
    public void LoginAdvice()
    {
        System.out.println("Advice run.. getMethod is called");
    }

    @Before("execution(* get*())")
    //@Before("allGetters()")
    public void SecondAdvice()
    {
        System.out.println("this is a second Advice");
    }
    @Pointcut("execution(* get*())")
    public void allGetters(){}

    //@Pointcut("execution (* * org.suman.Model.Circle.*(..))")
    @Pointcut("within(org.suman.Model.Circle)")
    public void allCircle(){}

} 

当使用切入点时,方法allGetters()为LoginAdvice方法,如果我使用@Before("execution(*get*())"然后没有错误但是如果我使用@Before("allGetters()")则会给出错误" java.lang.IllegalArgumentException::: 0处的错误找不到引用的切入点allGetters

如果我使用@Before("execution(*get*())&&(org.suman.Model.Circle)")而不是方法名称,它可以工作.

我的xml是这样的:
