Adding cookie in java and then HTTP redirect doesnt show cookie in client side
提问by Tejas
I have requirement where in i need to add cookie in java and then redirect it to different URL. Now this url process should persist the cookie which i set and after its processing send it back to client. The code goes as follows
我需要在java中添加cookie然后将其重定向到不同的URL。现在这个 url 进程应该保留我设置的 cookie，并在其处理后将其发送回客户端。代码如下
Cookie cookie = new Cookie("name", "value")
// To make sure cookie is established for all the url paths
cookie.setPath(request.getContextPath());
response.addCookie(cookie);
response.sendRedirect("someNewUrl");
Please help me regarding how can i persist the cookie throughout the redirect lifecycle and to the client. Thanks in advance.
请帮助我了解如何在整个重定向生命周期和客户端中保留 cookie。提前致谢。

尝试将cookie实际添加到响应中：
Cookie cookie = new Cookie("user", "anonymous");
response.addCookie(cookie);

Did you add the cookie to the response? I'm seeing the code that just creates the cookie.
您是否将 cookie 添加到响应中？我看到的只是创建 cookie 的代码。
Try this :
试试这个 ：
Cookie c = new Cookie(name,value);
c.setMaxAge( 3 * 30 * 24 * 60 * 60 );
c.setPath( "/" );
response.addCookie( c );
