在春季注销特定的请求映射

Question

I need on a particular RequestMapping make user logout. It can be several requestMappings. It would be fine if special annotation exist to do this.

Thanks in advance

Answer 1

If you are using spring authentication service (Spring Security), you can do it through configuration whereby you set a logout url and spring takes care of it.

Otherwise, you can yourself map an url as logout and upon invocation, you should invalidate the user session.

If you want to check if the user is logged in or not, you should check existence of already created session first.
