一、初始化工作:新徏一个项??ssh),在此目中导入对hibernate的支?新徏一个表sstest表，有字Did,username,password,idZ健和自动?
二、对新徏的数据表q行hibernateq行映射,打开myhibernate视图Q右Msstest?>选hibernate revers engineering选项Q然后把Sstest.hbm.xml文g映射到hibernateDao包中Q同旉中工具 hibernate mapping file...,  java data object.....,  java data access object dao...选项Q先中这几个文g可以生下列几?java文g:BaseHibernateDAO. ,HibernateSessionFactory ,IBaseHibernateDAO, Sstest,SstestDAO,最后你对你的代码进行测试，试成功Q进行下一?br /> 三、在目中导入对spring的支持，在导入项目后不但要自动生applicationContext.xml,而且在这个文仉会出C面的内容Q?br /> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
  <property name="configLocation" value="classpath:hibernate.cfg.xml">   
  </property>
 </bean>
q就是ؓ什么要先要导入hibernate的原?br /> 四、若你对spring的ioc比较熟，你可以直接进入下一步，如果不是很了解，那么你可以写一个比较简单的例子试一下看是否成功Q必竟框架和在一P所以小心点好，不然在以后出了有问题不好?br /> 五、进入myeclipse hibernate视图下，在新的包Q如springDaoQ中重新对sstest表进行映，q次映射要注意的是Q打开hibernate reverse engineering对话框中复选按钮java data access object(dao)(hibernate 3 only)下，dao type 不是选basic dao选项Q而是选spring dao选项Q当你映成功后Q就会出现Sstest.java, SstestDAO.java, Sstest.hbm.xml几个文gQ你可以写一个类q行试Q如Q?br /> springdaotest.java

package org.test;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import springDao.Sstest;
import springDao.SstestDAO;

public class SpringDaoTest {
 public static void main(String a[]){
  ApplicationContext cont = new ClassPathXmlApplicationContext("applicationContext.xml");
  SstestDAO  s = (SstestDAO) cont.getBean("SstestDAO");
   SstestDAO  s = (SstestDAO) cont.getBean("SstestDAOProxy");
  Sstest st = new Sstest();
  st.setUsername("spring");
  st.setPassword("spring");
  s.save(st);   
 } 
}
六、由于映了两次Q所以你要在hibernate.cfg.xml文g中，把原来映的文g注解掉：
<mapping resource="hibernateDao/Sstest.hbm.xml" />
因ؓ现在已有一行这L代码Q?br /> <mapping resource="springDao/Sstest.hbm.xml" />
七、实现hibernate spring 代理Q加上下面的代码卛_Q?br /> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
  <property name="sessionFactory">
   <ref local="sessionFactory"/>
  </property>
 </bean>
 <bean id="SstestDAOProxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
  <property name="proxyTargetClass">
   <value>true</value>
  </property>
  <property name="transactionManager">
   <ref bean="transactionManager"/>
  </property>
  <property name="target">
   <ref local="SstestDAO"/>
  </property>
  <property name="transactionAttributes">
   <props>
    <prop key="*">PROPAGATION_REQUIRED</prop>
   </props>
  </property>
 </bean>
在进行测试，试Ӟq是用原来的c，只需把SstestDAO  s = (SstestDAO) cont.getBean("SstestDAO");变成
SstestDAO  s = (SstestDAO) cont.getBean("SstestDAOProxy");q次的bean是用的代码类实现
下面是完整的代码Q?br /> 在这个实例中hibernate包中的文件BaseHibernateDAO. ,HibernateSessionFactory ,IBaseHibernateDAO, Sstest,SstestDAO, Sstest.hbm.xml Q和?a class="singleposttitle" id="viewpost1_TitleUrl" href="http://www.aygfsteel.com/qin/archive/2008/10/19/235318.html">一个简单的strutsQhibernate例子以及struts,hibernate集成中的文g是一LQ代码一P下面是一些其它代码：

一、新Z个项目（如sshQ?br /> 二、加入该目对struts的支持，是相关struts包，Q右M新徏的项目－>MyEclipseQ选add struts.........Q?br /> 三、添加了对struts支持后，然后在struts-config.xml文g里右击，新徏Q?gt;form action and jsp选项Q那样就可以把这三个文g新徏?register1.jsp,Register1Action.java,Register1Form.javaQ你可以把这三个文g发布到tomcatq行试Q，试成功可以执行下一?br /> 四、新Z个表sstest表，有字Did,username,password,idZ健和自动?
五，同样的方法添加对hibernate支持
六、对新徏的数据表q行hibernateq行映射,打开myhibernate视图Q右Msstest?>选hibernate revers engineering选项Q然后把Sstest.hbm.xml文g映射到hibernateDao包中Q同旉中工具 hibernate mapping file...,  java data object.....,  java data access object dao...选项Q先中这几个文g可以生下列几?java文g:BaseHibernateDAO. ,HibernateSessionFactory ,IBaseHibernateDAO, Sstest,SstestDAO,最后你对你的代码进行测试，试成功Q进行下一?br /> 七、好了，关于struts和hibernate代码基本上差不好了，下面来看一直代码，代码色的是集成的地?主要是看Register1Action代码,其它的代码都是自动生成的
相关代码如下Q?br /> register1.jsp
