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


<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"

	<aop:aspectj-autoproxy/>

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

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.jaraspectj-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
