}

        public void setItemDAO(IItemDAO itemDAO) {//此出给spring提供写入的方法

         this.itemDAO = itemDAO;

       }

       public void setOrderDAO(IOrderDAO orderDAO) {//此出给spring提供写入的方法

         this.orderDAO = orderDAO;

 3.3  Spring中有关此事务XML配置

   配置文件applicationContext.xml（注意相同颜色字之间的对应关系，其他bean的配置在此就省略掉了）。

<bean id="itemdao" class="com.trx.db.dao.ItemDAOImpl" autowire="byName" >

<bean id="orderdao" class="com.trx.db.dao.OrderDAOImpl " autowire="byName" >

<!--配置对应的Target-->

<bean id="itemBOTarget" class="com.trx.db.bo. TransactionTestImpl ">

        <property name="itemDAO"><!—此处对于上面定义的bean-->

          <ref bean="itemdao"/>

        </property>

        <property name="orderDAO">

          <ref bean="orderdao"/>

        </property>

     </bean>

<!--此处注入上面配置好的Target的ProxyFactoryBean-->

<bean id="transationBO" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">

        <property name="transactionManager">

            <ref bean="transactionManager" />

        </property>

        <property name="target">

            <ref local="itemBOTarget" />

        </property>

        <property name="transactionAttributes">

            <props>
