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"

<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
