使用ssh过程中对数据库进行update时报错

报错信息：org.springframework.dao.InvalidDataAccessApiUsageException:
Write operations are not allowed in read-only mode (FlushMode.NEVER) - turn your Session into FlushMode.AUTO or remove ‘readOnly‘ marker from transaction definition

beans.xml中的问题

<!-- 事务切面 -->

<bean id="tx" class="org.springframework.transaction.interceptor.TransactionInterceptor">

<property name="transactionManager" ref="tm"></property>

<property name="transactionAttributes">

<props>

<prop key="reg">PROPAGATION_REQUIRED</prop>

<prop key="task_*">PROPAGATION_REQUIRED</prop>

<prop key="*">PROPAGATION_REQUIRED</prop>

</props>

</property>

</bean>

加上红色部分语句就ok了！
