使用myeclipse 应用struts2 + spring + hibernate 实现CRUD

        struts2释出已经很久了,虽然自己现在作GUI开发,不过有时间还是学习下web开发,现在就将我使用myeclipse工具应用struts2 + spring + hibernate 实现CRUD操作的步骤一一纪录下来,为初学者少走弯路略尽绵薄之力!
       首先,myeclipse中web工程目录结构如下图:


       使用myeclipse开发hibernate和spring的操作我就不详细说了,网上的教程很多,如果有不明白的可以咨询我,呵呵.
      其中持久类AbstractTest,Test,TestDAO,Test.hbm.xml都是myeclipse的hibernate工具生成的.TestAction类是struts2的核心处理类,代码如下:

package  com.yangqiang.strutsdemo.web;

import  java.util.Collection;
import  java.util.List;

import  org.apache.log4j.Logger;

import  com.opensymphony.xwork2.ActionSupport;
import  com.yangqiang.strutsdemo.domain.Test;
import  com.yangqiang.strutsdemo.domain.TestDAO;

applicationContext.xml 主要是工具生成 的,只是将配置文件路径改下,代码如下:

<? xml version="1.0" encoding="UTF-8" ?>
<! DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd" >

< beans >


     < bean  id ="struts"
        class ="org.springframework.orm.hibernate3.LocalSessionFactoryBean" >
         < property  name ="configLocation" >
                         <!--  改变了一下 -->
             < value > /WEB-INF/classes/hibernate.cfg.xml </ value >
         </ property >
     </ bean >
     < bean  id ="testDao"
        class ="com.yangqiang.strutsdemo.domain.TestDAO" >
         < property  name ="sessionFactory" >
             < ref  bean ="struts"   />
         </ property >
     </ bean ></ beans >

struts.xml  (变化不大,写过以前struts配置文件的不难理解)
