		System.out.println("get:"+request.getParameter("xxx"));
		System.out.println("get:"+request.getParameter("yyy"));
	}

	protected void doPost(HttpServletRequest request,
			HttpServletResponse response) throws ServletException, IOException {
		
		request.setCharacterEncoding("utf-8");
		response.setContentType("text/html;charset=utf-8");
		
		String username = request.getParameter("username");
		String password = request.getParameter("password");
		String[] hobby = request.getParameterValues("hobby");
		
		System.out.println(username+","+password+","+Arrays.toString(hobby));
		
		
		Enumeration names2 = request.getParameterNames();
		while(names2.hasMoreElements()){
			System.out.println(names2.nextElement());
		}
//		Iterator names = (Iterator) request.getParameterNames();
//		while(names.hasNext()){
//			System.out.println(names.next());
//		}
		
		
			Map map = (Map)request.getParameterMap();
			for(String name:map.keySet()){
				String[] values = map.get(name);
				System.out.println(name+"="+Arrays.toString(values));
			}
		}
