JSP中利用URL重写传递参数的方法
：2010-10-14 18:26:30
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 k88.net
*/
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>翔宇亭IT乐园</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
hell
