问题

运行Spring测试程序，返回错误： AOP : java.lang.IllegalArgumentException: error at ::0 can't find referenced pointcut.

程序如下：

AspectJBean.java

package springcore.aspectj;

public class AspectJBean 

	public void display() 
		System.out.println( "AOPBean.display()!" );
	

AspectJMain.java

package springcore.aspectj;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class AspectJMain 

	public static void main(String[] args) 

		ClassPathXmlApplicationContext factory = new ClassPathXmlApplicationContext( "springcore/aspectj/AspectJBeans.xml" );
		
		AspectJBean aspectJBean = (AspectJBean)factory.getBean( "aspectJBean" );
		aspectJBean.display();
		
	

LoggerAspect.java

package springcore.aspectj;

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

@Aspect
public class LoggerAspect 

    @Pointcut("execution(public * *(..))")
    public void publicMethods()  

    @Pointcut("execution(* springcore.aspectj.LoggerAspect.*(..))")
    public void logObjectCalls()  

    @Pointcut("publicMethods()&&!logObjectCalls()")
    public void loggableCalls()  

	
    @Around("loggableCalls()")
	public Object aroundLogCalls(ProceedingJoinPoint joinPoint)
			throws Throwable 
		System.out.println("before invoke method:"
				+ joinPoint.getSignature().getName());
		Object object = joinPoint.proceed();
		System.out.println("after invoke method:"
				+ joinPoint.getSignature().getName());
		return object;
	

AspectJBeans.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:aop="http://www.springframework.org/schema/aop" 
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd">

	<aop:aspectj-autoproxy/>

	<bean id="loggerAspect" class="springcore.aspectj.LoggerAspect"/>
	<bean id="aspectJBean" class="springcore.aspectj.AspectJBean"/>
</beans>

解决

参考stackoverflow: AOP : java.lang.IllegalArgumentException: error at ::0 can’t find referenced pointcut

需要使用更高级一点的版本的aspectjrt.jar和 aspectj-weaver.jar, 进行Google，然后下载后进行替换，问题解决。

以上问题解决。显示如下：

before invoke method:display
AOPBean.display()!
after invoke method:display
