第一种

<aop:aspectj-autoproxy/>

import org.aspectj.lang.ProceedingJoinPoint;  
    import org.aspectj.lang.annotation.Around;  
    import org.aspectj.lang.annotation.Aspect;  
    import org.aspectj.lang.annotation.Before;  
    import org.aspectj.lang.annotation.Pointcut;  
    import org.springframework.stereotype.Component;  

    /** 
     * 基于注解的AOP日志示例 
     * @author ZYWANG 2011-3-24 
     */  
    @Component  
    @Aspect  
    public class AopLog {  

        @Pointcut("execution (* com.iflysse.school.services.impl.*.*(..))")  
        public void pointcut(){}  

        //方法执行前调用  
        @Before("pointcut()")  
        public void before() {  
            System.out.println("before");  
        }  

        //方法执行的前后调用  
        @Around("pointcut()")  
        public Object around(ProceedingJoinPoint point) throws Throwable{  
            System.out.println("begin around");  
            Object object = point.proceed();  
            System.out.println("end around");  
            return object;  
        }  
    }

第二种

import org.aspectj.lang.ProceedingJoinPoint;  

/** 
 * 基于配置文件的AOP日志示例 
 * @author ZYWANG 2011-3-24 
 */  
public class AopLog {  

    //方法执行的前后调用  
    public Object runOnAround(ProceedingJoinPoint point) throws Throwable{  
        System.out.println("begin around");  
        Object object = point.proceed();  
        System.out.println("end around");  
        return object;  
    }  

}

<aop:config>  
        <aop:aspect ref="aopLog">  
            <aop:around method="runOnAround" pointcut="execution (* com.zywang.services.impl.*.*(..))"/>  
        </aop:aspect>  
    </aop:config>
