本文实例总结了jsp和servlet中实现页面跳转的方式。分享给大家供大家参考,具体如下:

假设要求从test1.jsp 跳转到test2.jsp

一. jsp中跳转:

1. 使用RequestDispatcher.forward方法转发

<% 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标签

复制代码 代码如下:<jsp:forward page="test2.jsp"/>

4. html标记中的meta标记

复制代码 代码如下:<meta http-equiv="refresh" content="0; url=test2.jsp">

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 发送重定向请求

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

7. 使用javascript脚本

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

二. servlet中跳转:

假设 从 servlet中跳转到test2.jsp

1. forward

ServletContext sc = getServletContext(); RequestDispatcher rd = sc.getRequestDispatcher("/test/test2.jsp"); //定向的页面 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"); //定向的页面 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); } }

希望本文所述对大家JSP程序设计有所帮助。
