Does SessionStatus object.setComplete() clears all

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.
