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
