本文實(shí)例總結(jié)了jsp和servlet中實(shí)現(xiàn)頁面跳轉(zhuǎn)的方式。分享給大家供大家參考，具體如下：
假設(shè)要求從test1.jsp 跳轉(zhuǎn)到test2.jsp
一. jsp中跳轉(zhuǎn)：
1. 使用RequestDispatcher.forward方法轉(zhuǎn)發(fā)
%
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(biāo)簽
復(fù)制代碼 代碼如下:
jsp:forward page="test2.jsp"/>
4. html標(biāo)記中的meta標(biāo)記
復(fù)制代碼 代碼如下:
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 發(fā)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(zhuǎn)：
假設(shè) 從 servlet中跳轉(zhuǎn)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(shè)計(jì)有所幫助。
