原来是parent="txTargetManager"写错了，但是程序运行后，如果一个dao操作失败，另一个确直接插入了，不能回滚，不知道什么原因。spring 该不会是不能在service端管理事务吧？

wangdongzjk 写道 因为业务的需要，几个数据表之间并没有关系，但是要求在业务处理上考虑事务的问题，但是spring怎样管理多个dao的事务呢？ 你这样的声明只是对DAO做的,也就是说如果你单个DAO中出现异常等,事务会自动回滚的. 如果要达到对多个DAO的事务管理,你应该在service中调用多个dao,然后把事务声明在service层,这样如果一个DAO中出现问题,就会回滚整个service中所做的更改. 我觉得DAO中没有必要声明事务,完全可以放在service层. |

新的声明文件：
<bean id="myMenuServiceTarget" class="com.sales.service.impl.MenuManagerImpl">
<property name="menuDAO">
<ref bean="menuDAO"></ref>
</property>
<property name="permissionDAO">
<ref bean="permissionDAO"></ref>
</property>
</bean>
<bean id="myMenuService" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
<property name="transactionManager">
<ref bean="transactionManager"/>
</property>
<property name="target">
<ref bean="myMenuServiceTarget"/>
</property>
<property name="transactionAttributes">
<props>
<prop key="save*">PROPAGATION_REQUIRED</prop>
<prop key="update*">PROPAGATION_REQUIRED</prop>
<prop key="someOtherBusinessMethod">PROPAGATION_MANDATORY</prop>
</props>
</property>
</bean>
我做了如下修改： 更改数据库menu表的设置，把menuname（非主键）设成unique; 这样做是不会插入了，但是系统的异常捕获不到： Hibernate: insert into permission (permissionid, permissionparentid, permissionname, id); values (?, ?, ?, ?); Hibernate: insert into menu (parentid, menuname, menulink, id);
