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。
