Cookie的获取

1、先创建Cookie对象，设置Cookie的键和值：

        Cookie cookie1=");
        Cookie cookie2=");
        Cookie cookie3=");
        Cookie cookie4=");
        cookie1.setMaxAge(**);
        cookie2.setMaxAge(**);
        cookie3.setMaxAge(**);
        cookie4.setMaxAge(**);
        response.addCookie(cookie1);
        response.addCookie(cookie2);
        response.addCookie(cookie3);
        response.addCookie(cookie4);

2、再对Cookie进行遍历：

        Cookie [] cookies=request.getCookies();//获取Cookie数组
        if(cookies!=null){
            for (Cookie c:cookies){
                String name=c.getName();
                String value=c.getValue();
                System.out.println(name+" "+value);
            }
        }
