Spring与Hibernate两种组合方式

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"/>
