jsp和servlet中实现页面跳转的方式实例总结

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

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

4. html标记中的meta标记

<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。
