这篇文章主要介绍了jsp和servlet中实现页面跳转的方式,结合实例形式较为详细的总结分析了jsp和servlet中实现页面跳转的常用技巧,具有一定参考借鉴价值,需要的朋友可以参考下
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:
4. html标记中的meta标记
复制代码 代码如下:
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 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
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。
