hibernate异常：解决Hibernate的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.
方法1：在出现异常的方法中加入
|
1
|
getHibernateTemplate().setFlushMode(HibernateTemplate.FLUSH_EAGER);
|
方法2：重写OpenSessionInViewFilter

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。
