現在、私は基本的なログインシステムを作成する必要がある学校向けのプロジェクトを作成しています。問題は、@ Webservletアノテーションを使用すると、開始、これは私のサーブレットのコードです：「起動に失敗したローカルホストでサーバのTomcat V8.0 Serverの」@Webservletアノテーションを使用しているときにTomcatサーバーを起動できない
`package controller;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.ws.rs.NotAuthorizedException;
import handlers.RequestHandler;
import service.Service;
@WebServlet("/Controller")
public class Controller extends HttpServlet {
private static final long serialVersionUID = 1L;
private Service service = new Service();
private ControllerFactory controllerFactory = new ControllerFactory();
public Controller() {
super();
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
processRequest(request, response);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
processRequest(request, response);
}
protected void processRequest(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
String action = request.getParameter("action");
String destination = "index.jsp";
if (action != null) {
RequestHandler handler;
try {
handler = controllerFactory.getController(action, service);
destination = handler.handleRequest(request, response);
}
catch (NotAuthorizedException exc) {
List<String> errors = new ArrayList<String>();
errors.add(exc.getMessage());
request.setAttribute("errors", errors);
destination="index.jsp";
}
}
RequestDispatcher view = request.getRequestDispatcher(destination);
view.forward(request, response);
}
}

私は、このスタックトレースとエラーメッセージが表示されます、サーバーを起動します：
