第一种方式:每个Bean都有一个代理
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="configLocation" value="classpath:hibernate.cfg.xml" /> <property name="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration" /> </bean> <!-- 定义事务管理器(声明式的事务) --> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <!-- 配置DAO --> <bean id="userDaoTarget" class="com.bluesky.spring.dao.UserDaoImpl"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <bean id="userDao" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"> <!-- 配置事务管理器 --> <property name="transactionManager" ref="transactionManager" /> <property name="target" ref="userDaoTarget" /> <property name="proxyInterfaces" value="com.bluesky.spring.dao.GeneratorDao" /> <!-- 配置事务属性 --> <property name="transactionAttributes"> <props> <prop key="*">PROPAGATION_REQUIRED</prop> </props> </property> </bean> </beans>
第二种方式:所有Bean共享一个代理基类
第三种方式:使用拦截器
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="configLocation" value="classpath:hibernate.cfg.xml" /> <property name="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration" /> </bean> <!-- 定义事务管理器(声明式的事务) --> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <bean id="transactionInterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor"> <property name="transactionManager" ref="transactionManager" /> <!-- 配置事务属性 --> <property name="transactionAttributes"> <props> <prop key="*">PROPAGATION_REQUIRED</prop> </props> </property> </bean> <bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator"> <property name="beanNames"> <list> <value>*Dao</value> </list> </property> <property name="interceptorNames"> <list> <value>transactionInterceptor</value> </list> </property> </bean> <!-- 配置DAO --> <bean id="userDao" class="com.bluesky.spring.dao.UserDaoImpl"> <property name="sessionFactory" ref="sessionFactory" /> </bean> </beans>
第四种方式:使用tx标签配置的拦截器
<context:annotation-config /> <context:component-scan base-package="com.bluesky" /> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="configLocation" value="classpath:hibernate.cfg.xml" /> <property name="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration" /> </bean> <!-- 定义事务管理器(声明式的事务) --> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="*" propagation="REQUIRED" /> </tx:attributes> </tx:advice> <aop:config> <aop:pointcut id="interceptorPointCuts" expression="execution(* com.bluesky.spring.dao.*.*(..))" /> <aop:advisor advice-ref="txAdvice" pointcut-ref="interceptorPointCuts" /> </aop:config> </beans>
第五种方式:全注解
<context:annotation-config /> <context:component-scan base-package="com.bluesky" /> <tx:annotation-driven transaction-manager="transactionManager"/> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="configLocation" value="classpath:hibernate.cfg.xml" /> <property name="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration" /> </bean> <!-- 定义事务管理器(声明式的事务) --> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> </beans>
此时在DAO上需加上@Transactional注解,如下:
