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

阅读更多

错误代码:
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
错误原因:
OpenSessionInViewFilter在getSession的时候,会把获取回来的session的flush mode 设为FlushMode.NEVER。然后把该sessionFactory绑定到 TransactionSynchronizationManager,使request的整个过程都使用同一个session,在请求过后再解除该 sessionFactory的绑定,最后closeSessionIfNecessary 根 据该session是否已和transaction绑定来决定是否关闭session。在这个过程中,若HibernateTemplate 发现自当前session有不是readOnly的transaction,就会获取到FlushMode.AUTO Session,使方法拥有写权限。
也即是,如果有不是readOnly的transaction就可以由Flush.NEVER转为Flush.AUTO,拥有 insert,update,delete操作权限,如果没有transaction,并且没有另外人为地设flush model的话,则doFilter的整个过程都是Flush.NEVER。所以受transaction保护的方法有写权限,没受保护的则没有。

解决办法:
采用spring的事务声明,使方法受transaction控制
<bean id="baseTransaction"
class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"
abstract="true">
<property name="transactionManager" ref="transactionManager"/>
<property name="proxyTargetClass" value="true"/>
<property name="transactionAttributes">
<props>
<prop key="get*">PROPAGATION_REQUIRED,readOnly</prop>
<prop key="find*">PROPAGATION_REQUIRED,readOnly</prop>
<prop key="load*">PROPAGATION_REQUIRED,readOnly</prop>
<prop key="save*">PROPAGATION_REQUIRED</prop>
<prop key="add*">PROPAGATION_REQUIRED</prop>
<prop key="update*">PROPAGATION_REQUIRED</prop>
<prop key="remove*">PROPAGATION_REQUIRED</prop>
</props>
</property>
</bean>
    <bean id="userService" parent="baseTransaction">
<property name="target">
<bean class="com.phopesoft.security.service.impl.UserServiceImpl"/>
</property>
</bean>
