Servlet提供404而不是加载适当的页面。启动Tomcat时控制台说SEVERE错误

For some reason Apache Tomcat 7.0 doesn't run my main servlet(PlaceListServlet) that should list a bunch of database items on place-list.jsp page.

出于某种原因,Apache Tomcat 7.0不运行应该在place-list.jsp页面上列出一堆数据库项的主servlet(PlaceListServlet)。

I keep getting 404 everywhere, and Eclipse doesn't report any errors in the source.

我一直在到处获得404,Eclipse不会在源代码中报告任何错误。

What seems to be the problem?

什么似乎是问题?

PlaceListServlet.java (main servlet that should load place-list.jsp):

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

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 {
    }

}

EDIT:

I just looked at the console and saw this error:

我只是看着控制台,看到了这个错误:
