import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class HelloServlet extends HttpServlet {
        private void process(HttpServletRequest req,HttpServletResponse resp )
        throws ServletException,IOException {
           System.out.println("ok!!!!!!!!!!!!!");
           String u = req.getParameter("user");
           String p = req.getParameter("pass"); 
           resp.setContentType("text/html; charset=gb2312");
           PrintWriter pw = resp.getWriter();
           pw.print("<h1>你好" + u + " 你的密码是" + p + "</h1>");
           
           pw.close();
    
    
        }
        protected void doGet(HttpServletRequest req,HttpServletResponse resp)
        throws ServletException,IOException {
