问题
I am not clear about this if I use SessionStatus object.setComplete() in a Controller, does it clears all the session data of the Webapp or just clears the session data saved by a particular controller in which @SessionAttributes is used?
回答1:
SessionStatus#setComplete() JavaDoc is pretty clear about the method's purpose:
/**
* Mark the current handler's session processing as complete, allowing for
* cleanup of session attributes.
*/
This clears the current handler's session attributes registered via @SessionAttribute. This is completely different from servlet's HttpSession#invalidate():
/**
* Invalidates this session then unbinds any objects bound to it.
*/
This one actually destroys the user session completely.
