注销在浏览器上留下了JSESSIONID.如何清除它？

Question

我使用以下代码从我的系统注销用户.

/**
 * This function helps to set the session attribute for the present user to null and then
 * removes the attribute itself and this helps in clearing the session
 * @param request
 * @param response
 */
@RequestMapping(value = AuthConstants.EXIT, method = RequestMethod.POST)
public void exitPrime(HttpServletRequest request, HttpServletResponse response) {
        /*Getting session and then invalidating it*/
        HttpSession session = request.getSession(false);
        if(request.isRequestedSessionIdValid() && session != null)
        {
            session.invalidate();

        }
}

这导致成功注销,但登录时提供的JSESSION ID仍然保留在浏览器中,因为对于任何新用户,在登录时再次使用相同的JSESSION ID.我希望JSESSIONID cookie仅对当前会话有效,一旦用户注销,它将被销毁或无效以便下次完成登录.我的登录代码如下: -

/**
 * This method allows one to log into the system and generates a token for a valid employee.
 * @param authRequest
 * @param request
 * @param response
 * @return
 */
@RequestMapping(value = AuthConstants.ENTRY, method = RequestMethod.POST, consumes = ApplicationConstants.APPLICATION_JSON)
public @ResponseBody
AuthResponse primeEntry(@RequestBody AuthRequest authRequest,HttpServletRequest request, HttpServletResponse response) {
    AuthResponse authResponse = new AuthResponse();
    if(authRequest != null && authRequest.getEmployeeAuth().getEmployeeNumber() != null 
            && !authRequest.getEmployeeAuth().getEmployeeNumber().isEmpty()){
        /*To check whether the user is valid*/
        String employeeNumber = authRequest.getEmployeeAuth().getEmployeeNumber();
        UserBean userBean = new UserBean();
        userBean = userService.getUser(employeeNumber);
        if(userBean != null)
            {
            HttpSession session = request.getSession(true);
            session.setAttribute("user", userBean);
            setAuthResponseSuccess(authResponse);
        }else{
            /*If user does not exist the too throw error 500*/
            setAuthResponseFailure(authResponse);
        }
    }else{
        /*If input JSON is not valid then throw error 500*/
        setAuthResponseFailure(authResponse);
    }
    return authResponse;
}

我正在使用Spring 3.2并希望手动登录和注销.请帮忙.

Answer 1

经过一番实验后我得出结论,如果你想让浏览器cookie值继续存在,那么就不要做任何事情,上面的代码对你来说也没问题.另一方面,如果你想要cookie的输出

Set-Cookie: JSESSIONID=""; Expires=Thu, 01-Jan-1970 00:00:10 GMT; Path=/

然后,您可以使用此代码段并尝试一下.

private void handleLogOutResponseCookie(HttpServletResponse response) {
        Cookie[] cookies = request.getCookies();
        for (Cookie cookie : cookies) {
            cookie.setMaxAge(0);
            cookie.setValue(null);
            cookie.setPath("/");
            response.addCookie(cookie);
        }

这将解决问题并在您注销时销毁cookie.

只要浏览器上的JSESSIONID剩余已经无效,它就没有任何问题.JSESSIONID只是一堆不包含实际数据的随机字符.

但是我怀疑你的问题是你@SessionAttributes在类级别使用了注释,而你试图session.invalidate().在上一个会话失效后的情况下,Spring会自动为您创建一个新会话(和JSESSIONID),因为它必须将指定的模型属性保存到会话中.

IMO更好的方法是创建一个新的控制器,该控制器没有@SessionAttributes并使会话无效.
