transient,persistent or detached
| After going through the life cycle, the question that comes into mind is that, how does hibernate know whether an object is transient,persistent or detached ? A range of options are available for that. Hibernate will assume that an instance is unsaved Transient instance if : a) The identifier property is null b) The version property (if exists) is null. c) You supply an unsaved-value attribute in matches. d) You supply Hibernate Interceptor and return Boolean.TRUE from Interceptor.isUnsaved() after checking the instance in your code. |
