java - 我设置了cookie的max age，但是cookie依然在关闭游览器后消失了

Question

我设置了cookie的max age，但是cookie依然在关闭游览器后消失了。
我的controller：

package com.jiaotong114.jiaotong.controller;
@Controller
@RequestMapping("/")
public class CityIndex { 
@RequestMapping(value="/city/{cityName}", method = RequestMethod.GET)
public String printHello(ModelMap model, @PathVariable("cityName") String cityName, HttpServletRequest request, HttpServletResponse response) {

    Cookie[] c = request.getCookies();
    boolean isNew = true;
    for(int i = 0; i < c.length; i++) {
        if(c[i].getName().equals("cityName")) {
            c[i].setValue(cityName);
            c[i].setMaxAge(365 * 24 * 60 * 60);
            response.addCookie(c[i]);
            isNew = false;
        }
    }
    if(isNew) {
        Cookie cityNameCookie = new Cookie("cityName", cityName);
        cityNameCookie.setMaxAge(365 * 24 * 60 * 60);
        response.addCookie(cityNameCookie);
    }
    request.getSession().setAttribute("cityName", cityName);
    return "index";
}
}

访问http://localhost:8080/city/sh...调用这个controller，可以从图片看到cookie已经被成功添加到客户端了，时间是一年。

但是当我关闭了游览器，重新打开，访问http://localhost:8080，然后发现我的cookie不见了。见图2。

Answer 1

The problem is solved, cookie.setPath("/") is set

Answer 2

It’s a browser problem. . . . .

Answer 3

cookie是由多个属性决定的，我猜max-age is just one of them.
