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");
