java - Servlet 给出 404 而不是加载适当的页面。控制台在启动 Tomcat 时显示严重错误

Question

出于某种原因 Apache Tomcat 7.0 没有运行我的主 servlet(PlaceListServlet)，它应该在 place-list.jsp 上列出一堆数据库项目 页面。

我到处都是 404，而且 Eclipse 没有报告源代码中的任何错误。

似乎是什么问题？

PlaceListServlet.java(应该加载的主要 servlet place-list.jsp):

package com.myproject.crud;

import java.io.IOException;

import javax.inject.Inject;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@SuppressWarnings("serial")
@WebServlet({"/place/", "index.jsp"})
public class PlaceListServlet extends HttpServlet {

    @Inject
    private PlaceRepositoryImpl placeRepo = new PlaceRepositoryImpl();

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        request.setAttribute("places", placeRepo.listPlaces());
        getServletContext().getRequestDispatcher("/WEB-INF/pages/place-list.jsp").forward(request, response);
    }

    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    }

}

编辑:

我刚刚查看了控制台，看到了这个错误:
