本文實例總結了jsp和servlet中實現頁面跳轉的方式。分享給大家供大家參考，具體如下：
假設要求從test1.jsp 跳轉到test2.jsp
一. jsp中跳轉：
1. 使用RequestDispatcher.forward方法轉發
<% 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標簽
4. html標記中的meta標記
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：
假設 從 servlet中跳轉到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程序設計有所幫助。
