Spring Aop XML 配置实现_spring 2.5 jdk1.7 增加aop切面xml配置-优快云博客

本文详细介绍如何在Spring框架中使用AOP（面向切面编程），包括所需jar包、XML配置及AOP类实现。通过具体代码示例，展示了如何定义切点、引入AspectJ并创建环绕通知，以实现在方法调用前后进行日志记录。

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"?><!-- 一般化的Spring XML 配置 -->
<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>
	
	<!-- 为接口类设置切点 -->
	<aop:config>
		<aop:aspect ref="loggerAspect">
			<!-- 之前 -->
			<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;
    }
}
