form表单提交在后台怎么获取option的值

具体代码如下：
jsp代码：
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

Servlet代码：
public class DemoServlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String name = request.getParameter("name");
System.out.println(name);
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doGet(request, response);
}
}
其中DemoServlet是一个继承了HttpServlet类的Servlet类，当表单提交（点击提交按钮）时，回去调用这个类的doPost()方法，执行对应的代码，通过request.getParameter("name")来获取表单的值。
