创建会话时添加另一个cookie [英] Add another cookie when session is created

问题描述

在以struts 2(javax.servlet v 2.5和嵌入式tomcat lib)开发的Web应用程序中，在创建HttpSession时(第一次调用请求时)，在第一个请求之后，我总是将JSESSIONID始终自动添加到cookie中.getSession())，我知道JSESSIONID旨在标识创建的http会话.

In my web application developed in struts 2 (javax.servlet v 2.5 and an embedded tomcat lib), I have the JSESSIONID always automatically added to the cookies after the first request when a HttpSession is created (at first call to request.getSession()), I know that the JSESSIONID aims to identify the created http session.

现在我想添加更多cookie，但是我没有找到如何在struts 2框架中添加此cookie?以及用户注销后如何将其从响应的Cookie中删除.

Now I want to add more cookies but I don't found how to adding this cookie in the framework struts 2? and how can I remove it from the cookie of the response when user logged out.

推荐答案

添加cookieName Cookie:

Add cookieName Cookie:

Cookie newCookie = new Cookie("cookieName", "cookieValue");
newCookie.setMaxAge(60*60*24*365); //Store cookie for 1 year
response.addCookie(newCookie);

然后将其删除:

Cookie[] cookies = request.getCookies();

if (cookies != null) {
 for (Cookie cookie : cookies) {
   if (cookie.getName().equals("cookieName")) {
     cookie.setValue("");
     cookie.setPath("/");
     cookie.setMaxAge(0);
     resp.addCookie(cookie);
  }
 }     
}
