本文介绍如何使用Spring框架整合Hibernate，实现声明式事务管理。通过Eclipse引入必要的jar包，并配置log4j进行日志记录。详细说明了如何设置数据源、SessionFactory及事务管理器，并通过配置事务拦截器实现对DAO层的事务控制。

作为开源框架，Spring很好的支持了hibernate,通过Spring的声明式事务很好解决了，hiberante事务问题、、、

一、用eclipse开发引入spring+hibernate jar包,利用spring配置管理hibernate.

二、编写 log4j.properties文件

#错误的级别，存放器分别控制台与文件
log4j.rootLogger =error,A,R

   #A可随便写，输出控制台，自己指定布局格式
   log4j.appender.A = org.apache.log4j.ConsoleAppender
   log4j.appender.A.layout = org.apache.log4j.PatternLayout
   log4j.appender.A.layout.ConversionPattern = [%t] %-5p %c %x - %m%n

   #R可随便写，输出在文件，文件位置/立即刷新/最大改寸/备份个数/布局格式
   log4j.appender.R=org.apache.log4j.RollingFileAppender
   log4j.appender.R.File=c:\logger.log
   log4j.appender.R.ImmediateFlush=true
   log4j.appender.R.MaxFileSize=100KB
   log4j.appender.R.MaxBackupIndex=1
   log4j.appender.R.layout=org.apache.log4j.PatternLayout
   log4j.appender.R.layout.ConversionPattern=%d{ABSOLUTE} [%t] %-5p %-30c{3} %x - %m %n

三、配置 ApplicationContext.xml

<?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="datasource"
  class="org.apache.commons.dbcp.BasicDataSource">
  <property name="driverClassName">
   <value>oracle.jdbc.driver.OracleDriver</value>
  </property>
  <property name="url">
   <value>jdbc:oracle:thin:@localhost:1521:orcl</value>
  </property>
  <property name="username">
   <value>terry</value>
  </property>
  <property name="password">
   <value>terry</value>
  </property>
</bean>
<bean id="SessionFactory"
  class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
  <property name="dataSource">
   <ref bean="datasource" />
  </property>
  <property name="hibernateProperties">
   <props>
    <prop key="hibernate.dialect">
     org.hibernate.dialect.Oracle9Dialect
    </prop>
    <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.format_sql">true</prop>
                
                <prop key="hibernate.query.factory_class">org.hibernate.hql.classic.ClassicQueryTranslatorFactory</prop>
   </props>
  </property>
  <property name="mappingResources">
   <list>
    <value>org/terry/hibernate/pojo/Stu.hbm.xml</value></list>
  </property>
  </bean>
  
   <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
   <property name="sessionFactory" ref="SessionFactory"></property>
   </bean>
   
   <bean id="transactionIterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor">
   
   <property name="transactionManager" ref="transactionManager"></property>
   <property name="transactionAttributes">
     <props>
      <prop key="insert*">PROPAGATION_REQUIRED</prop>
      <prop key="find*,get*">PROPAGATION_REQUIRED,readOnly</prop>
      <prop key="*">PROPAGATION_REQUIRED</prop>
     </props>
   </property>
   </bean>

   <bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
   <property name="beanNames">
     <list>
      <value>*Dao</value>
     </list>
   </property>
   <property name="interceptorNames">
     <list>
      <value>transactionIterceptor</value>
     </list>
   </property>
   </bean>
   
  <bean class="org.terry.hibernate.base.imp.DaoBeanImp" name="beanImp">
   <property name="sessionFactory" ref="SessionFactory"></property>
  </bean>

<bean id="daoTemplate" abstract="true" lazy-init="true">
   <property name="sessionFactory" ref="SessionFactory"></property>
  </bean>
  <bean class="org.terry.hibernate.dao.StuDao" name="stu" parent="daoTemplate">

</bean>

</beans>

四、编写具体实现类

1.继承 HibernateDaoSupport

2.使用 HibernateTemplate 模板

五、测试

通过ClassPathXmlApplicationContext 得到 ApplicationContext 对象，通过其 getBeans("")得到具体实现类
