这篇文章主要介绍了JavaWeb Refresh响应头代码实例详解,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下

一.Refresh响应头：可以理解为定时的重定向，在指定的时间后发生页面的跳转

二.代码示例：

package cn.xxx.Servlet;

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class DServlet extends HttpServlet {

  protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    response.getWriter().print("xxxx");
    //3秒之后跳转到/Demo01/EServlet
    response.setHeader("refresh", "3;URL=/Demo01/EServlet");
  }
}

package cn.xxx.Servlet;

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class EServlet extends HttpServlet {
  
  protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
