Logout

Spring Security provides a logout endpoint by default. Once logged in, you can GET /logout to see a default logout confirmation page, or you can POST /logout to initiate logout. This will:spring-doc.cn

clear the ServerCsrfTokenRepository, ServerSecurityContextRepository, andspring-doc.cn
redirect back to the login pagespring-doc.cn

Often, you will want to also invalidate the session on logout. To achieve this, you can add the WebSessionServerLogoutHandler to your logout configuration, like so:spring-doc.cn
