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。
