Cookies小代码测试出现问题

Question

package com.mison;

import java.io.IOException;

import java.io.PrintWriter;

import javax.servlet.ServletException;

import javax.servlet.http.Cookie;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

public class CookieServlet extends HttpServlet {

private int cookiem;
private int cookien;
public void doGet(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {
     Cookie cookie =new Cookie("cookiename" +cookiem++,
             "cookievalue"+cookien++);

      cookie.setMaxAge(15);

      response.addCookie(cookie);

      Cookie []cookies =request.getCookies();

      if(null==cookies){
          return;
      }
          for(Cookie c:cookies){
              System.out.println("CookieName:"+c.getName());
              System.out.println("CookieValue:"+c.getValue());

      }
}


}

运行上面的Cookies测试代码  为什么就马上出现如下  而不是刷新一次 出现一次  怎么一次性出现8个

CookieName:cookiename0
CookieValue:cookievalue 0
CookieName:cookiename1
CookieValue:cookievalue 1
CookieName:cookiename2
CookieValue:cookievalue 2
CookieName:cookiename3
CookieValue:cookievalue 3
CookieName:cookiename4
CookieValue:cookievalue 4
CookieName:cookiename5
CookieValue:cookievalue 5
CookieName:cookiename6
CookieValue:cookievalue 6
CookieName:cookiename7
CookieValue:cookievalue 7
CookieName:cookiename8
CookieValue:cookievalue 8

Answer 1

那么多，应该是你之前留在浏览器里的。
[code="java"]
response.addCookie(cookie);
[/code]
这行代码每次会像cookie里加一个记录（因为你cookie的name不同）

话又说回来，cookiem和cookien的++操作让我又很费解，估计是经过若干次修改之后遗留下来的。
建议你将代码重构一下，还有，运行之前，先把浏览器的缓存和cookie清除一下。
