HttpServlet：此URL不支持HTTP方法POST ——问题解决

让servlet中的doGet执行doPost方法，会报错，

去掉super就可以了。

具体原因：点我查看具体原因

	@Override
	protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
		super.doPost（req，resp）；加上super就会报错，
		doPost(req, resp);		  去掉super就可以了；
	}

	@Override
	protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
		//�����ַ�����
		req.setCharacterEncoding("utf-8");
		resp.setContentType("text/html;charset=utf-8");
