spring method interceptor

leisure — Wed, 11 Jul 2012 01:14:00 GMT

spring method interceptor

-author: leisure.xu

首先dao里面有find和save�Ҏ��Q�本实例以拦截find�Ҏ��Z��Q��ƈ改变find的返回倹{�?/span>

package com.leisure;

public class Dao {

public String find() {

System. out.println( "dao: find()");

return "student";

}

public void save() {

System. out.println( "dao: save()");

}

一、新增一个DaoInterceptor,如下

package com.leisure;

import org.aopalliance.intercept.MethodInterceptor;

import org.aopalliance.intercept.MethodInvocation;

/**

* class description goes here

* @author leisure.xu

* @version 1.0.0, 2012 -6 -29

public class DaoInterceptor implements MethodInterceptor {

@Override

public Object invoke(MethodInvocation invocation) throws Throwable {

String methodName = invocation.getMethod().getName();

if( "find".equals(methodName)) {

System. out.println( "invocation modify the return result to 'teacher'");

return "teacher";

}

return invocation.proceed();

}

DaoInterceptor实现了MethodInterceptor的invoke�Ҏ��Q�在�q�里�Q?/span>MethodInvocation参数可以获取到getArguments�{�数据，至于能做什么，你懂的�?/span>

二、Dao跟DaoInterceptor�q�是没扯上关�p�，�q�时需要修改applicationContext.xml

原来�Q?/span>

修改为：

property >

<list >

<value >daoInterceptor value >

list >

property >

bean >

三、运行看效果�Q?/span>

ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml" );

Dao dao = context.getBean(Dao. class);

System. out.println(dao.find());

dao.save();

�l�果�Q?/span>

invocation modify the return result to 'teacher'

teacher

dao: save()

从结果可以看出invocation拦截了find�Ҏ��Q��ƈ且修改了其返回结果，而对象的find�Ҏ��q�没有执行到�?/span>

该实例引用到的jar包：
