這篇文章主要介紹了jsp和servlet中實(shí)現(xiàn)頁面跳轉(zhuǎn)的方式,結(jié)合實(shí)例形式較為詳細(xì)的總結(jié)分析了jsp和servlet中實(shí)現(xiàn)頁面跳轉(zhuǎn)的常用技巧,具有一定參考借鑒價(jià)值,需要的朋友可以參考下

本文實(shí)例總結(jié)了jsp和servlet中實(shí)現(xiàn)頁面跳轉(zhuǎn)的方式。分享給大家供大家參考，具體如下：

假設(shè)要求從test1.jsp 跳轉(zhuǎn)到test2.jsp

一. jsp中跳轉(zhuǎn)：

1. 使用RequestDispatcher.forward方法轉(zhuǎn)發(fā)

<%
 RequestDispatcher rd = getServletContext().getRequestDispatcher("/test/test2.jsp"); 
 rd.forward(request, response); 
%>

2. response.sendRedirect 重定向

<%
  response.sendRedirect("test2.jsp");
%>

3. 使用forward標(biāo)簽

復(fù)制代碼代碼如下:

<jsp:forward page="test2.jsp"/>

4. html標(biāo)記中的meta標(biāo)記

復(fù)制代碼代碼如下:

5. 使用response.setHeader

<%
int stayTime=0;
String URL="test2.jsp";
String content=stayTime+";URL="+URL; 
response.setHeader("REFRESH",content);
%>

6. 使用response.setHeader和response.setStatus 發(fā)送重定向請求

<%
 response.setStatus(HttpServletResponse.SC_MOVED_PERMANENTLY); 
 String newLocation = "test2.jsp"; 
 response.setHeader("Location",newLocation); 
%>

7. 使用javascript腳本

<script type="text/javascript">
window.location.href="test2.jsp";
</script>

二. servlet中跳轉(zhuǎn)：

假設(shè) 從 servlet中跳轉(zhuǎn)到test2.jsp

1. forward

ServletContext sc = getServletContext(); 
RequestDispatcher rd = sc.getRequestDispatcher("/test/test2.jsp"); //定向的頁面 
rd.forward(request, response);
public class ForwardServlet extends HttpServlet {
 public void doGet(HttpServletRequest request, HttpServletResponse response)
  throws ServletException, IOException {
 String id = request.getParameter("id");
 response.setContentType("text/html; charset=gb2312"); 
 ServletContext sc = getServletContext(); 
 RequestDispatcher rd = sc.getRequestDispatcher("/test/test2.jsp"); //定向的頁面 
 rd.forward(request, response); 
 }
 public void doPost(HttpServletRequest request, HttpServletResponse response)
  throws ServletException, IOException {
 doGet(request, response);
 }
}

2. sendRedirect

package com.yanek.test;
import java.io.IOException;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class RedirectServlet extends HttpServlet {
 public void doGet(HttpServletRequest request, HttpServletResponse response)
  throws ServletException, IOException {
 String id = request.getParameter("id");
 response.setContentType("text/html; charset=gb2312"); 
 response.sendRedirect("test/test2.jsp");
 }
 public void doPost(HttpServletRequest request, HttpServletResponse response)
  throws ServletException, IOException {
 doGet(request, response);
 }
}

希望本文所述對大家JSP程序設(shè)計(jì)有所幫助。
