java中用s2sh做得项目好像是事务出现了问题求解决

Question

使用ss2h开发的web项目，用jsp做数据显示，用mysql做数据库，用spring做控制事务的
spring配置文件中的配置信息

tx:attributes

        <tx:method name="add*" propagation="REQUIRED" />
        <tx:method name="del*" propagation="REQUIRED" />
        <tx:method name="update*" propagation="REQUIRED" />
        <tx:method name="do*" propagation="REQUIRED" />
        <tx:method name="*" read-only="true" />
   </tx:attributes>
</tx:advice>

下面是报错信息
HTTP Status 500 -
