hibernate4在sessionFactory的配置中,和hibernate3有些区别,hibernate4使用org.springframework.orm.hibernate4.LocalSessionFactoryBean配置sessionFactory.而hibernate3使用org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean类配置sessionFactory
请看以下hibernate4的sessionFactory配置代码:
<!-- Hibernate4配置 --> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="packagesToScan" value="实体类存在的包" /> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">${hibernate.dialect}</prop> <prop key="hibernate.show_sql">${hibernate.show_sql}</prop> <prop key="hibernate.format_sql">${hibernate.format_sql}</prop> </props> </property> </bean>hibernate3的sessionFactory使用配置,用annotatedClasses属性显示指定实体类,配置代码如下:
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="annotatedClasses"> <list> <value>com.example.Foo</value> <value>com.example.Bar</value> </list> </property> </bean>hibernate3的sessionFactory使用配置,用packagesToScan属性让spring自动查找实体类,配置代码如下:
<beanid="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="packagesToScan" value="test.package"/> </bean>
