下面介紹一下hibernate與spring的集成,這兩個(gè)框架的集成關(guān)鍵在于applicationContext.xml文件的配置，其實(shí)很簡(jiǎn)單的，但需要注意的是，導(dǎo)入包時(shí)一定選擇導(dǎo)入到webroot/web-inf/lib目錄中，而且hibernate一般要在spring之前導(dǎo)入，因?yàn)榧蓵r(shí)要用到sessionFactory類,
一、初始化工作:新建一個(gè)項(xiàng)目,如(ssh),在此項(xiàng)目中導(dǎo)入對(duì)hibernate的支持,新建一個(gè)表sstest表，有字段id,username,password,id為主健和自動(dòng)增1
二、對(duì)新建的數(shù)據(jù)表進(jìn)行hibernate進(jìn)行映射,打開(kāi)myhibernate視圖，右擊你sstest表->選hibernate revers engineering選項(xiàng)，然后把Sstest.hbm.xml文件映射到hibernateDao包中，同時(shí)選中工具 hibernate mapping file...,  java data object.....,  java data access object dao...選項(xiàng)，先中這幾個(gè)文件就可以產(chǎn)生下列幾個(gè).java文件:BaseHibernateDAO. ,HibernateSessionFactory ,IBaseHibernateDAO, Sstest,SstestDAO,最后你對(duì)你的代碼進(jìn)行測(cè)試，測(cè)試成功，進(jìn)行下一步
三、在項(xiàng)目中導(dǎo)入對(duì)spring的支持，在導(dǎo)入項(xiàng)目后不但要自動(dòng)產(chǎn)生applicationContext.xml,而且在這個(gè)文件里會(huì)出現(xiàn)下面的內(nèi)容：
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
  <property name="configLocation" value="classpath:hibernate.cfg.xml">   
  </property>
 </bean>
這就是為什么要先要導(dǎo)入hibernate的原因
四、若你對(duì)spring的ioc比較熟，你可以直接進(jìn)入下一步，如果不是很了解，那么你可以寫(xiě)一個(gè)比較簡(jiǎn)單的例子測(cè)試一下看是否成功，必竟框架和在一起，所以小心點(diǎn)好，不然在以后出了有問(wèn)題不好找
五、進(jìn)入myeclipse hibernate視圖下，在新的包（如springDao）中重新對(duì)sstest表進(jìn)行映射，這次映射要注意的就是：打開(kāi)hibernate reverse engineering對(duì)話框中復(fù)選按鈕java data access object(dao)(hibernate 3 only)下，dao type 不是選basic dao選項(xiàng)，而是選spring dao選項(xiàng)，當(dāng)你映射成功后，就會(huì)出現(xiàn)Sstest.java, SstestDAO.java, Sstest.hbm.xml幾個(gè)文件，你可以寫(xiě)一個(gè)類進(jìn)行測(cè)試，如：
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、由于映射了兩次，所以你要在hibernate.cfg.xml文件中，把原來(lái)映射的文件注解掉：
<mapping resource="hibernateDao/Sstest.hbm.xml" />
因?yàn)楝F(xiàn)在已有一行這樣的代碼：
<mapping resource="springDao/Sstest.hbm.xml" />
七、實(shí)現(xiàn)hibernate spring 代理，加上下面的代碼即可：
<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>
在進(jìn)行測(cè)試，測(cè)試時(shí)，還是用原來(lái)的類，只需把SstestDAO  s = (SstestDAO) cont.getBean("SstestDAO");變成
SstestDAO  s = (SstestDAO) cont.getBean("SstestDAOProxy");這次的bean是用的代碼類實(shí)現(xiàn)
下面是完整的代碼：
在這個(gè)實(shí)例中hibernate包中的文件BaseHibernateDAO. ,HibernateSessionFactory ,IBaseHibernateDAO, Sstest,SstestDAO, Sstest.hbm.xml ，和在一個(gè)簡(jiǎn)單的struts，hibernate例子以及struts,hibernate集成中的文件是一樣的，代碼一樣，下面是一些其它代碼：
