Cookie常用方法封装Utils

1、查询某个指定的cookie

package com.sun.etalk.cookie;

import javax.servlet.http.Cookie;

public class CookieUtils {
    /**
     * 在Cookie数组中查找指定name cookie
     */
    public static Cookie findCookie(Cookie[] cookies, String name){
        if(cookies == null){
            return null;
        }else{
            for (Cookie cookie : cookies) {
                if(cookie.getName().equals(name)){
                    return cookie;
                }
            }
            return null;
        }
    }
}

 使用方法：

Cookie cookie = CookieUtils.findCookie(request.getCookies(), "history");
