hibernate异常:解决Hibernate的Write operations are not allowed in read-only mode (FlushMode.NEVER) .....

报错:

Write operations are not allowed in read-only mode (FlushMode.NEVER) - turn your Session into FlushMode.AUTO or remove 'readOnly' marker from transaction definition

解决方法:

在方法体中加入

getHibernateTemplate().setFlushMode(HibernateTemplate.FLUSH_EAGER);

解决

另附未测试方法

方法2:重写OpenSessionInViewFilter

    <init-param>
        <param-name>singleSession</param-name>

    </init-param>
</filter>
<filter-mapping
    <filter-name>hibernateFilter</filter-name>

</filter-mapping>

总结:

Write operations are not allowed in read-only mode (FlushMode.NEVER/MANUAL): Turn your Session into FlushMode.COMMIT/AUTO or remove ‘readOnly’ marker from transaction definition.

很明显,从上面的异常信息可以清晰地知道在事务切入的方法中(数据库写入操作)必须将session设置为FlushMode.COMMIT或者FlushMode.AUTO。
