spring+hibernate 两种整合方式配置文件

来源：互联网发布：tabletoexcel.js 编辑：程序博客网时间：2024/06/06 03:52

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
 print?

                <prop key="hibernate.hbm2ddl.auto">${hbm2ddl.auto}</prop>  
            </props>  
        </property>  
    </bean>  
    <bean id="txManager"  
        class="org.springframework.orm.hibernate4.HibernateTransactionManager">

    </bean>  
    <tx:advice id="txAdvice" transaction-manager="txManager">  
        <tx:attributes>  
            <tx:method name="get*" read-only="true" />  
            <tx:method name="*" />

    </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
 print?
<?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">

    </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">

            <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 "*"
