我有spring应用程序，我已经实现了签名功能，但它不起作用。当用户登录时，我通过设置属性将用户登录详细信息维护为会话中的bean "UserDTO“，当用户单击”注销“超链接，然后在我正在执行的”注销“函数中，通过使用请求scope.here获取会话无效作为代码。

代码语言：javascript
复制
  @RequestMapping(value="/SignOut",method = RequestMethod.GET) 
    public String signOut(HttpServletRequest request){
           HttpSession session=request.getSession(); 
 System.out.println("session id before invalidating it:"+session.getId());
          UserDTO userDTO=(UserDTO)session.getAttribute("UserDTO");
          System.out.println("userDTO obje"+userDTO.getFirst_name());
          session.removeAttribute("UserDTO");   
    session.invalidate(); 
System.out.println("session id after invalidating session is:"+session.getId()); 
}

在使会话is:8E8AE156B9AE963C9C2E9BCB0B9B13DB无效后，在使会话会话id无效之前，我将得到相同的会话id :8E8AE156B9A9A963C9C2E9BCB0B9B13DB会话id。

您可以尝试使用另一个控制器进行签名：

代码语言：javascript
复制
    @Controller
    @RequestMapping("/SignOut")
    public class SignOutController {

      @RequestMapping(method=RequestMethod.GET)
      public String logout(HttpSession session) {
        session.invalidate();
        return "redirect:/home";
      }
    }

问题在于会话中的UserDTO对象。注释它并检查它是否无效。
