spring配置文件中几种配置事务的方式:
第一种:通过aop管理用户的增删改 (aspectJ)
 <aop:config>
 <aop:advisor pointcut="execution(* *..OrderDao.*(..))"
 advice-ref="txAdvice" />
 </aop:config>
 <tx:advice id="txAdvice">
 <tx:attributes>
 <tx:method name="save*" />
 <tx:method name="update*" />
 <tx:method name="delete*" />
 <tx:method name="*" read-only="true" />
 </tx:attributes>
 </tx:advice>
第二种:通过拦截器
Dao实现类实例
<bean name="dao" class="org.itfuture.www.dao.impl.OrderDaoImpl">
 <property name="sessionFactory" ref="sessionFactory"></property>
</bean>
 事务bean
<bean id="baseproxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
 <property name="transactionManager" ref="transactionManager"/>
 <property name="target" ref="dao"/>//所在拦截的目标指向
 <property name="transactionAttributes">//拦截目标内的哪些方法
 <props>
 <prop key="delete*">PROPAGATION_REQUIRED</prop>
 <prop key="save*">PROPAGATION_REQUIRED</prop>
 <prop key="update*">PROPAGATION_REQUIRED</prop>
 <prop key="select*">PROPAGATION_REQUIRED,readOnly</prop>
 <prop key="query*">PROPAGATION_REQUIRED,readOnly</prop>
 </props>
 </property>
</bean>
创建orderservice子类(实现类)的实例,注入 orderDao的实现类orderimpl的实例
<bean name="orderservice"
 class="org.itfuture.www.service.impl.OrderServiceImpl">
 <property name="dao" ref="baseproxy"></property>//引用baseproxy代理
</bean>
第三种配置:aop与interceptor相接合
<bean id="transactionInterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor">
 <property name="transactionManager" ref="transactionManager">//引用transactionManager
 </property>
 <property name="transactionAttributes">//定义哪些方法是要用到事务的,
 <props>
 <prop key="delete*">PROPAGATION_REQUIRED</prop>
 <prop key="save*">PROPAGATION_REQUIRED</prop>
 <prop key="update*">PROPAGATION_REQUIRED</prop>
 <prop key="add*">PROPAGATION_REQUIRED</prop>
 <prop key="*">PROPAGATION_REQUIRED,readOnly</prop>
 </props>
 </property>
 </bean>
 <bean id="auto" class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
 <property name="interceptorNames">
 <list>
 <value>transactionInterceptor</value>
 </list>
 </property>
 </bean>
第四种配置:个人认为比较好用这种
<bean id="dao" class="org.itfuture.www.dao">//把所有的*dao上升到接口
 <property name="accountDao" ref="accountDao"/>
 <property name="categoryDao" ref="categoryDao"/>
 <property name="productDao" ref="productDao"/>
 <property name="itemDao" ref="itemDao"/>
 <property name="orderDao" ref="orderDao"/>
 </bean>
 <aop:config>
 <aop:advisor pointcut="execution(* *..interfaceDao.*(..))" advice-ref="txAdvice"/> //然后在拦截接口
 </aop:config>
 <tx:advice id="txAdvice">
 <tx:attributes>
 <tx:method name="insert*"/>//拦截接口中的以insert、update、update开头的所有方法
 <tx:method name="update*"/>
 <tx:method name="*" read-only="true"/>//其它方法,只read-only
 </tx:attributes>
 </tx:advice>
