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);
}

}

[解决办法]
你的说法没错
但你可以：System.out.println(request.getMethod());
看看究竟是post还是get
