Spring与Hibernate两种组合方式[转]

http://developer.51cto.com/art/200906/131127.htm

Spring与Hibernate大致有两种组合方式，主要区别是一种是在Hibernate中的hibernate.cfg.xml中配置数据源，一种是借助Spring的jdbc方式在Spring的applicationContext.xml文件中配置数据源,然后在Spring配置sessionFactory的bean有些区别：

下面大致的说明一下

第一种

1.hibernate.cfg.xml文件

    xml version='1.0' encoding='utf-8'?>
            "-//Hibernate/Hibernate Configuration DTD 3.0//EN" 
            "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
    
    <hibernate-configuration>
    
        <session-factory>
    
            
            <property name="connection.driver_class">com.microsoft.jdbc.sqlserver.SQLServerDriverproperty>
            <property name="connection.url">jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=acegi;SelectMethod=cursorproperty>
            <property name="connection.username">saproperty>
            <property name="connection.password">serverproperty>
            <property name="show_sql">trueproperty>
    
             <mapping resource=""/>
    
        session-factory>
    
    hibernate-configuration>

2.在spring配置sessionFactory

    <bean id="sessionFactory"    class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
       <property name="configLocation" value="classpath:hibernate.cfg.xml"></property>
     </bean>
     <bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"></property>
     </bean>
     <tx:annotation-driven transaction-manager="txManager"/>

或者实现hibernate零配置

    <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
       <property name="configLocation" value="classpath:hibernate.cfg.xml"></property>
        <property name="packagesToScan" value="com/wch/entity/"></property>
     </bean>
     <bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"></property>
     </bean>
     <tx:annotation-driven transaction-manager="txManager"/>

第二种

    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
             <property name="driverClassName" value="com.microsoft.jdbc.sqlserver.SQLServerDriver"/>
             <property name="url" value="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=acegi;SelectMethod=cursor"/>
             <property name="username" value="sa"/>
             <property name="password" value="server"/>
    
    
       </bean>
       
     <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
       <property name="dataSource" value="dataSource"></property>
    
    <property name="mappingResources">
         <list>
                  <value>user.hbm.xml</value>
         </list>
     </property>
     <property name="hibernateProperties">
          <props>
            <prop key="hibernate.show_sql">true</prop>
       </props>
      </property>
     </bean>   
    
        </bean>
     <bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"></property>
     </bean>
     <tx:annotation-driven transaction-manager="txManager"/>

或者实现hibernate的零配置

    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
            <property name="driverClassName" value="com.microsoft.jdbc.sqlserver.SQLServerDriver"/>
            <property name="url" value="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=acegi;SelectMethod=cursor"/>
            <property name="username" value="sa"/>
            <property name="password" value="server"/>
      </bean>
      
    <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
      <property name="dataSource" value="dataSource"></property>
       <property name="packagesToScan" value="com/wch/entity/"></property>
    </bean>
    <bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
       <property name="sessionFactory" ref="sessionFactory"></property>
    </bean>
    <tx:annotation-driven transaction-manager="txManager"/>
