今天在做ssh项目开发的时候遇到一个问题，保存数据的时候报错：

Write operations are not allowed in read-only mode (FlushMode.NEVER/

后参考这篇文章才知道出了什么问题：http://www.aichengxu.com/view/37412

原来在Spring事务管理中save类的方法都没有read-only=true，但是我的方法是add*，所以就出现开头讲的问题，把add*方法改成save*就可以了。

<!-- 配置事务策略 -->

    <tx:advice id="txAdvice" transaction-manager="myTxManager">

        <tx:attributes>

            <tx:method name="find*" propagation="REQUIRED" read-only="true" />

            <tx:method name="save*" propagation="REQUIRED" />

            <tx:method name="*" propagation="SUPPORTS" read-only="true" />

        </tx:attributes>

    </tx:advice>
