本文讲解了在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页中的内容：

/**

*

* @comefrom cuoxin.com

*/

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中的内容:

<%--

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>错新网CUOXIN</title>

</head>

<body>

<%

String name = request.getParameter("name");

String a = request.getParameter("sid");

out.print(a + "<br>" + name);

%>

</body>

</html>

3.输出结果：

5748
