【springboot】退出后清除session的内容并让session失效

https://blog.youkuaiyun.com/s740556472/article/details/71275328

@RequestMapping("/logout")
public String logout(HttpSession session, SessionStatus sessionStatus){
    session.invalidate();
    sessionStatus.setComplete();
    return "redirect:/login";
}

session.invalidate();只是让session失效 但session仍然存在。
