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

1. xml version=‘1.0‘ encoding=‘utf-8‘?>
2. "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
3. "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
4. <hibernate-configuration>
5. <session-factory>
6. <property name="connection.driver_class">com.microsoft.jdbc.sqlserver.SQLServerDriverproperty>
7. <property name="connection.url">jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=acegi;SelectMethod=cursorproperty>
8. <property name="connection.username">saproperty>
9. <property name="connection.password">serverproperty>
10. <property name="show_sql">trueproperty>
11. <mapping resource=""/>
12. session-factory>
13. hibernate-configuration>

2.在spring配置sessionFactory

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

或者实现hibernate零配置

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

第二种

1. <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
2. <property name="driverClassName" value="com.microsoft.jdbc.sqlserver.SQLServerDriver"/>
3. <property name="url" value="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=acegi;SelectMethod=cursor"/>
4. <property name="username" value="sa"/>
5. <property name="password" value="server"/>
6. </bean>
7. <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
8. <property name="dataSource" value="dataSource"></property>
9. <property name="mappingResources">
10. <list>
11. <value>user.hbm.xml</value>
12. </list>
13. </property>
14. <property name="hibernateProperties">
15. <props>
16. <prop key="hibernate.show_sql">true</prop>
17. </props>
18. </property>
19. </bean>
20. </bean>
21. <bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
22. <property name="sessionFactory" ref="sessionFactory"></property>
23. </bean>
24. <tx:annotation-driven transaction-manager="txManager"/>

或者实现hibernate的零配置

1. <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
2. <property name="driverClassName" value="com.microsoft.jdbc.sqlserver.SQLServerDriver"/>
3. <property name="url" value="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=acegi;SelectMethod=cursor"/>
4. <property name="username" value="sa"/>
5. <property name="password" value="server"/>
6. </bean>
7. <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
8. <property name="dataSource" value="dataSource"></property>
9. <property name="packagesToScan" value="com/wch/entity/"></property>
10. </bean>
11. <bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
12. <property name="sessionFactory" ref="sessionFactory"></property>
13. </bean>
14. <tx:annotation-driven transaction-manager="txManager"/>
