gender:<input type="radio" name="gender" value="male">male

<input type="radio" name="gender" value="female">female

<input type="submit" value="login">

</form>



</body>

</html>



	public void doPost(HttpServletRequest request,HttpServletResponse response) throws IOException, ServletException{

		String sign = request.getParameter("zodiac_sign");

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

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

		response.setContentType("text/html");

		PrintWriter out = response.getWriter();

		out.println("<html><body>Hello "+userName+sign+"<br>");

		out.println("</body></html>");

		out.close();

	}

其他值的获取正常，只有select 下拉菜单的值为null值
