核心提示:在servlet页中重定向到index.jsp页,但重写index.jsp页的URL传递两个参数给index页 1.Servlet页: /** * * @author lucifer */ package MyServlet;import java.io.IOException;import java.io.PRint

在servlet页中重定向到index.jsp页,但重写index.jsp页的URL传递两个参数给index页

1.Servlet页:


/**
 *
 * @author lucifer
 */


package MyServlet;

import java.io.IOException;
import java.io.PRintWriter;
import javax.servlet.*;
import javax.servlet.http.*;


public class URLRewritingServlet extends HttpServlet {
 
   protected void processRequest(HttpServletRequest request, HttpServletResponse response)
   throws ServletException, IOException {
     response.setContentType("text/html;charset=UTF-8");
     PrintWriter out = response.getWriter();
     String urI = response.encodeRedirectURL("http://localhost:8084/LearnServlet/index.jsp?sid=5748&name=hell");
     response.sendRedirect( urI );

   try {
       out.println("<html>");
       out.println("<head>");
       out.println("<title>Servlet URLRewritingServlet</title>"); 
       out.println("</head>");
       out.println("<body>");
       out.println("<h1>Servlet URLRewritingServlet at " + request.getContextPath () + "</h1>");
       out.println("</body>");
       out.println("</html>");
     } finally {
       out.close();
     }
   }

   @Override
   public void init(ServletConfig config)throws ServletException{
     super.init(config);
   }

   @Override
   protected void doGet(HttpServletRequest request, HttpServletResponse response)
   throws ServletException, IOException {
     processRequest(request, response);
   }

   @Override
   protected void doPost(HttpServletRequest request, HttpServletResponse response)
   throws ServletException, IOException {
     processRequest(request, response);
   }

   @Override
   public String getServletInfo() {
     return "Short description";
   }

}

2.index.jsp:

<%--
   Document  : index
   Created on : 2009-10-13, 12:59:28
   Author   : lucifer
--%>

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
  "http://www.w3.org/TR/html4/loose.dtd">

<html>
   <head>
     <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
     <title>JSP Page</title>
   </head>
   <body>
     <%
        String name = request.getParameter("name");
        String a = request.getParameter("sid");
        out.print(a + "<br>" + name);
     %>
   </body>
</html>


3.输出:

5748

hell
