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"/>
