奇怪，为什么html中form的method是get，为什么我最后提交数据时地址栏没有显示数据，不是post没有吗？

import java.io.IOException;

import java.io.PrintWriter;



import javax.servlet.ServletException;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;





public class ThreeParams extends HttpServlet {



	@Override

	protected void doGet(HttpServletRequest req, HttpServletResponse resp)

			throws ServletException, IOException {

		PrintWriter pw = resp.getWriter();

		resp.setContentType("text/html");

		pw.println(req.getParameter("param1"));

		pw.println("<br/>");

		pw.println(req.getParameter("param2"));

		pw.println("<br/>");

		pw.println(req.getParameter("param3"));

		pw.println("<br/>");

	}



	protected void doPost(HttpServletRequest req, HttpServletResponse resp)

			throws ServletException, IOException {

			doGet(req,resp);

	}



}
