spring hibernate配置spring和hibernate集成包括哪些步骤

配置spring和hibernate集成包括哪些步骤

spring和hibernate集成的步骤如下： 1、将hibernate的配置加入到Spring的配置中(这里以datasource和sessionfactory为例进行配置说明): <bean id="dataSource" class=&.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" /> <property name="url" value="jdbc:oracle:thin:@localhost:1521:ORCL" /> <property name="username" value="user" /> <property name="password" value="pwd" /> </bean> <bean id="mySessionFactory" class=&.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="mappingResources"> <list> <value&/test/spring/hibernate/Hbtest.hbm.xml </value> </list> </property> <property name="hibernateProperties"> <value> hibernate.hibernate.dialect.Oracle10gDialect hibernate.show_sql=true hibernate.format_sql=true hibernate.current_session_context_class=thread </value> </property> </bean> Hibernate的配置也可以单独放在hibernate.cfg.xml文件中,然后通过如下的配置指向config文件,这样在spring配置中就不要配置dataSource和其他Hibernate相关的信息了。 <bean id="mySessionFactory" class=&.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="configLocation" value="classpath:conf/Hibernate.cfg.xml" /> </bean> 2、将sessionfactory注入到DAO中,通过sessionfactory操作Hibernate提供的API: <bean id="PlainHibernateDAO" class=&.test.spring.hibernate.PlainHibernateDAO"> <property name="sessionFactory" ref="mySessionFactory" /> </bean> 3、配置事务管理： （1）显式用Hibernate提供的 SessionFactory.getCurrentSession().beginTransaction()mit自动提交事务，那么在hibernateProperties要配置hibernate.current_session_context_class=thread： <span style="color:#000000;"> <property name="hibernateProperties"> <value> hibernate.current_session_context_class=thread </value> </span> （2）利用Spring的事务声明来做管理:hibernateProperties不能配置hibernate.current_session_context_class=thread <tx:advice id="txAdvice" transaction-manager="txManager"> <tx:attributes> <tx:method name="*" propagation="REQUIRED"/> </tx:attributes> </tx:advice> <bean id="txManager" class=&.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="mySessionFactory" /> </bean> <aop:config> <aop:pointcut id="persistOperation" expression="execution(*.test.spring.hibernate.PlainHibernateDAO.*(..))" /> <aop:advisor advice-ref="txAdvice" pointcut-ref="persistOperation" /> </aop:config>
