spring事务管理配置总结 （最容易理解的）

事务代理标准写法

<!--DAO层接口实现  -->
<bean id="userDAO" class="net.test.dao.UserDAO">
       <property name="sessionFactory">
              <ref local="sessionFactory" />
       </property>
</bean>
 <!--业务层接口实现，把DAO注入到Service里面 --> 
<bean name="userServiceTarget" class="net.test.service.UserService">
       <property name="userDAO">
              <ref bean="userDAO" />
       </property>
</bean>
<!--spring代理业务层的事务管理 -->
<bean id="userServiceProxy"  class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
       <property name="transactionManager">
              <ref local="transactionManager" />
       </property>
       <property name="transactionAttributes">
              <props>
                    <prop key="insert*">PROPAGATION_REQUIRED</prop>
                    <prop key="find*">PROPAGATION_REQUIRED,readOnly</prop>
              </props>
       </property>
       <property name="target">
              <ref bean="userServiceTarget" />
       </property>
</bean>

事务代理简写法

<bean id="baseTxProxy" lazy-init="true"
        class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
        <property name="transactionManager">
            <ref bean="transactionManager" />
        </property>
        <property name="transactionAttributes">
            <props>
                <prop key="insert*">PROPAGATION_REQUIRED</prop>
                <prop key="find*">PROPAGATION_REQUIRED,readOnly</prop>
            </props>
        </property>
    </bean>
    <bean id="userDAO" class="net.test.dao.UserDAO">
        <property name="sessionFactory">
            <ref local="sessionFactory" />
        </property>
    </bean>
    <bean id="userServiceProxy" parent="baseTxProxy">
        <property name="target">
            <bean class="net.test.service.UserService">
                <property name="userDAO">
                    <ref local="userDAO" />
                </property>
            </bean>
        </property>
    </bean>

事务自动化代理写法

<!-- 定义事务拦截器bean -->
    <bean id="transactionInterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor">
        <property name="transactionManager" ref="transactionManager"/>
        <property name="transactionAttributes">
            <props>
                <prop key="insert*">PROPAGATION_REQUIRED</prop>
                <prop key="update*">PROPAGATION_REQUIRED</prop>
                <prop key="delete*">PROPAGATION_REQUIRED</prop>
                <prop key="find*">PROPAGATION_REQUIRED,readOnly</prop>
                <prop key="query*">PROPAGATION_REQUIRED,readOnly</prop>
                <prop key="*">PROPAGATION_REQUIRED</prop>
            </props>
        </property>
    </bean>
    <!--定义BeanNameAutoProxyCreator-->
    <bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
        <property name="beanNames">
        <!--
             所有名字以DAO,Service结尾的bean,
            将由该"bean后处理器"为其创建事务代理;
            实际上应该在业务层进行事务管理,
            这里只是举一个简单例子 
            -->
            <value>*DAO,*ServiceProxy</value>
        </property>
        <!--下面定义BeanNameAutoProxyCreator所需的事务拦截器-->
        <property name="interceptorNames">
            <list>
            <!--可以增加其他的拦截器-->
            <value>transactionInterceptor</value>
            </list>
        </property>
    </bean>
    <bean id="userDAO" class="net.test.dao.UserDAO">
        <property name="sessionFactory">
            <ref local="sessionFactory" />
        </property>
    </bean>
    <bean id="userServiceProxy" class="net.test.service.UserService">
        <property name="userDAO">
            <ref bean="userDAO" />
        </property>
    </bean>
