SSH2只能添加不能修改删除，求解
据说跟事务有关 看了下事务配置，求大虾帮忙看看。
<!--
对事务管理器进行事务设置。增加如下代码： 这里创建了一个advice(通知)，对事务管理器进行事务设置，这里意思是指，
对于以save、del、update开头的方法应用事务。
-->
<tx:advice id="smAdvice" transaction-manager="transactionManager">
<!-- 设置事务传播属性 -->
<tx:attributes>
<tx:method name="find*" propagation="REQUIRED" />
<tx:method name="get*" propagation="REQUIRED" />
<tx:method name="display*" propagation="REQUIRED" />
<tx:method name="view*" propagation="REQUIRED" />
<tx:method name="save*" propagation="REQUIRED" />
<tx:method name="del*" propagation="REQUIRED" />
<tx:method name="update*" propagation="REQUIRED" />
<tx:method name="insert*" propagation="REQUIRED" />
<tx:method name="edit*" propagation="REQUIRED" />
<tx:method name="create*" propagation="REQUIRED" />
<tx:method name="delete*" propagation="REQUIRED" />
</tx:attributes>
</tx:advice>
<tx:annotation-driven transaction-manager="transactionManager"/>
<!-- 下面就把事务应用到具体的类 -->
<aop:config>
<!--
<aop:pointcut id="smMethod" expression="execution(*
cn.app.cost.buz.impl.*.*(..))"/>
-->
<aop:pointcut id="smMethod" expression="execution(* cn.*.buz.impl.*.*(..))" />
<aop:advisor pointcut-ref="smMethod" advice-ref="smAdvice" />
