之前的文章都是讲解springmvc+spring+mybatis 的整合，而很少有springmvc+spring+hibernate 因为工作的需要，最近在使用hibernate 所以下面我们来看看 spring整合hibernate的配置文件，这里只说spring+hibernate 的配置文件而不说springmvc 因为这些是不用变的。spring整合hibernate 有两种方式 1、注解方式 2、xml方式实现1、注解方式实现：  applicationContext.xml配置文件：[html] view plain copy<?xml version="1.0" encoding="UTF-8"?>  <beans xmlns="http://www.springframework.org/schema/beans"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xmlns:aop="http://www.springframework.org/schema/aop"       xmlns:tx="http://www.springframework.org/schema/tx"       xmlns:context="http://www.springframework.org/schema/context"       xsi:schemaLocation="           http://www.springframework.org/schema/beans

class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">        <property name="locations">          <list>              <value>classpath:jdbc.properties</value>          </list>        </property>      </bean>      <bean id="c3p0DataSource" destroy-method="close"          class="com.mchange.v2.c3p0.ComboPooledDataSource">          <property name="driverClass" value="${driverClass}" />          <property name="jdbcUrl" value="${url}" />          <property name="user" value="${user}" />          <property name="password" value="${password}" />

<property name="maxIdleTime" value="${maxIdleTime}" />      </bean>                       <bean id="sessionFactory"          class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">          <property name="dataSource" ref="c3p0DataSource" />          <property name="packagesToScan">              <list>                  <value>com.test.bean</value>              </list>          </property>          <property name="hibernateProperties">              <props>                  <prop key="hibernate.dialect">${dialect}</prop>                  <prop key="hibernate.show_sql">${show_sql}</prop>                  <prop key="hibernate.format_sql">${format_sql}</prop>                  <prop key="hibernate.use_sql_commants">${use_sql_comments}</prop>

class="org.springframework.orm.hibernate4.HibernateTransactionManager">          <property name="sessionFactory" ref="sessionFactory" />      </bean>      <tx:advice id="txAdvice" transaction-manager="txManager">          <tx:attributes>              <tx:method name="get*" read-only="true" />              <tx:method name="*" />          </tx:attributes>      </tx:advice>      <aop:config>          <aop:pointcut id="bizMethods" expression="execution(* com.test.biz.*.*(..))" />          <aop:advisor advice-ref="txAdvice" pointcut-ref="bizMethods" />      </aop:config>  </beans>  2.xml方式实现applicationContext.xml配置：[html] view plain copy<?xml version="1.0" encoding="UTF-8"?>  <beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xmlns:aop="http://www.springframework.org/schema/aop"    xmlns:tx="http://www.springframework.org/schema/tx"    xsi:schemaLocation="http://www.springframework.org/schema/beans                        http://www.springframework.org/schema/beans/spring-beans.xsd                        http://www.springframework.org/schema/tx                        http://www.springframework.org/schema/tx/spring-tx.xsd                        http://www.springframework.org/schema/aop                        http://www.springframework.org/schema/aop/spring-aop.xsd">                 <!-- 让spring 去读取指定路径下的资源文件 -->      <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">        <property name="locations" value="classpath:jdbc.properties"/>      </bean>            <!-- 配置c3p0连接池 -->      <bean id="c3p0Source" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">        <property name="driverClass" value="${driverClass}" />        <property name="jdbcUrl"

<property name="minPoolSize" value="${minPoolSize}" />        <property name="maxPoolSize" value="${maxPoolSize}" />        <property name="maxIdleTime" value="${maxIdleTime}" />      </bean>            <!-- 配置SessionFactory -->      <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">        <property name="dataSource" ref="c3p0Source" />        <property name="mappingResources">            <list>              <value>/com/cdzg/spring/bean/User.hbm.xml</value>            </list>        </property>        <property name="hibernateProperties">

          </props>        </property>      </bean>            <!-- 配置事务管理器 -->      <bean id="txManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">        <property name="sessionFactory" ref="sessionFactory" />      </bean>            <!-- 定义事务通知 -->      <tx:advice id="txAdvice" transaction-manager="txManager">        <tx:attributes>          <tx:method name="get*" read-only="true"/>          <tx:method name="*"/>        </tx:attributes>      </tx:advice>              <!-- 定义事务切面，并应用事务通知 -->           <aop:config>        <aop:pointcut id="xxxBizImpl" expression="execution(* com.cdzg.spring.biz.*.*(..))"/>        <aop:advisor pointcut-ref="xxxBizImpl" advice-ref="txAdvice"/>       </aop:config>                 <bean id="userDaoImpl" class="com.cdzg.spring.dao.impl.UserDaoImpl">          <property name="sessionFactory" ref="sessionFactory" />      </bean>      <bean id="userBizImpl" class="com.cdzg.spring.biz.impl.UserBizImpl">          <property name="userDao" ref="userDaoImpl" />      </bean>      <bean id="userAction" class="com.cdzg.spring.web.actions.UserAction">          <property name="userBiz" ref="userBizImpl" />      </bean>  </beans>  两种配置最大的区别就是注解方式不用在写O/R映射配置文件而xml方式实现的要配置O/R映射配置文件

上面红色部分注解的这种方式，直接扫描bean包就可以，剩下的对应关系由框架完成而xml配置方式要配置O/R 映射文件并在这里指定文件，如果多的话可以使用通配符 "*"转载地址：http://my.oschina.net/xiaoen/blog/122439
