异常记录
spring 环境下做一个保存操作时，抛出如下异常：

org.springframework.dao.InvalidDataAccessApiUsageException: Write operations are not allowed in read-only mode (FlushMode.MANUAL): Turn your Session into FlushMode.COMMIT/AUTO or remove 'readOnly' marker from transaction definition.

<!-- 配置事务特性 -->

<tx:advice id="txAdviceBHO" transaction-manager="transactionManager">    <tx:attributes>       <tx:method name="save*" propagation="REQUIRED" />       <tx:method name="update*" propagation="REQUIRED" />       <tx:method name="delete*" propagation="REQUIRED" />       <tx:method name="*" read-only="true" propagation="NEVER"/>    </tx:attributes></tx:advice>

原因 在于配置事务时有错误，我调用的方法为orderSave，操作为保存数据，而在如下配置中针对此方法只能做读取操作，就出现了如上异常
