1、需要jar包

aopalliance-1.0.jar
    asm-3.3.1.jar
    aspectj-1.7.1.jar
    aspectjrt-1.7.0.jar
    aspectjweaver-1.7.0.jar
    cglib-2.2.2.jar

2、xml配置

<?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:context="http://www.springframework.org/schema/context"
    		xmlns:util="http://www.springframework.org/schema/util"
    		xmlns:aop="http://www.springframework.org/schema/aop" 
    		xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    				http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
    				http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
    				http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd">
    				<context:annotation-config/>
    	<bean id="loggerAspect" class="com.my.spring.aop.LogAspect"></bean>
    	
    	
    	<aop:config>
    		<aop:aspect ref="loggerAspect">
    			
    			<aop:around pointcut="execution(* com.my.remotting.server.*.*(..))" method="log"/>
    		</aop:aspect>
    	</aop:config>
    </beans>

3、aop类

import org.aspectj.lang.ProceedingJoinPoint;
    import org.aspectj.lang.reflect.MethodSignature;
    
    public class LogAspect{
    	
    	public Object log(ProceedingJoinPoint joinPoint) throws Throwable {
            System.out.println("我在被监视程序之前。。。");
          /*  Object[] args = joinPoint.getArgs(); 
            Object object = joinPoint.proceed(args);*/
            Object object = joinPoint.proceed();
            System.out.println("我在被监视程序之后。。。" );
            MethodSignature signature = (MethodSignature) joinPoint.getSignature();  
            String methodName = signature.getDeclaringTypeName() + "." + signature.getName(); 
            System.out.println("methodName="+methodName);
            return object;
        }
    }
