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'?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>

    <session-factory>

        <!-- Database connection settings -->
        <property name="connection.driver_class">com.microsoft.jdbc.sqlserver.SQLServerDriver</property>
        <property name="connection.url">jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=acegi;SelectMethod=cursor</property>
        <property name="connection.username">sa</property>
        <property name="connection.password">server</property>
        <property name="show_sql">true</property>

         <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"/>
