spring+hibernate 两种整合方式配置文件的方法

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：

<?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 
     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 
     http://www.springframework.org/schema/context 
     http://www.springframework.org/schema/context/spring-context.xsd"> 
  <context:component-scan base-package="com.test" /> 
  <bean 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="initialPoolSize" value="${initialPoolSize}" /> 
    <property name="minPoolSize" value="${minPoolSize}" /> 
    <property name="maxPoolSize" value="${maxPoolSize}" /> 
    <property name="maxIdleTime" value="${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> 
        <prop key="hibernate.hbm2ddl.auto">${hbm2ddl.auto}</prop> 
      </props> 
    </property> 
  </bean> 
  <bean id="txManager" 
    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：

<?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="${driverClass}" /> 
   <property name="jdbcUrl" value="${url}" /> 
   <property name="user" value="${user}" /> 
   <property name="password" value="${password}" /> 
   <property name="initialPoolSize" value="${initialPoolSize}" /> 
   <property name="minPoolSize" value="${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> 
        <prop key="hibernate.dialect">${dialect}</prop> 
        <prop key="hibernate.hbm2ddl.auto">${hbm2ddl.auto}</prop> 
        <prop key="hibernate.show_sql">${show_sql}</prop> 
        <prop key="hibernate.format_sql">${format_sql}</prop> 
        <prop key="hibernate.use_sql_comments">${use_sql_comments}</prop> 
      </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

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 "*"
