為什么Post()請求不了點不進去

public?class?HelloServlet?extends?HttpServlet?{
????@Override
????protected?void?doGet(HttpServletRequest?request,?HttpServletResponse?response)?throws?ServletException,?IOException?{
????????PrintWriter?out=response.getWriter();
????????System.out.println("處理Get()請求....");
????????response.setContentType("text/html;charset=UFT-8");
????????out.println("<strong>HttpServlet</strong><br/>");
????}

????@Override
????protected?void?doPost(HttpServletRequest?request,?HttpServletResponse?response)?throws?ServletException,?IOException?{
????????PrintWriter?out=response.getWriter();
????????System.out.println("處理Post()請求....");
????????response.setContentType("text/html;charset=UFT-8");
????????out.println("<strong>HttpServlet</strong><br/>");
????}
}

處理Get()請求...
