运行 REST with Java(JAX-RS) with Jersey on IntelliJ / Tomcat

Question

我正在 OSX 上尝试在 IntelliJ 中完成以下教程：

http://www.vogella.com/tutorials/REST/article.html

虽然运行在 Eclipse 中编译代码一切正常。但是运行 IntelliJ 中的代码会为相同的 URI 提供 404。

该程序应该运行在 Apache Tomcat 服务器 8.0.20 上。

我完全按照教程中的内容进行了操作，但我不明白为什么它在 IntelliJ 中不起作用。我已经搜索了几天，找到了解决方案。

看起来部署有问题，因为 index.jsp 工作正常。

希望有人能帮助我。

程序代码：

Class 您好：

package com.vogella.jersey.first;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

// Plain old Java Object it does not extend as class or implements 
// an interface

// The class registers its methods for the HTTP GET request using the @GET annotation. 
// Using the @Produces annotation, it defines that it can deliver several MIME types,
// text, XML and HTML. 

// The browser requests per default the HTML MIME type.

//Sets the path to base URL + /hello
@Path("/hello")
public class Hello {

    // This method is called if TEXT_PLAIN is request
    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String sayPlainTextHello() {
        return "Hello Jersey";
    }

    // This method is called if XML is request
    @GET
    @Produces(MediaType.TEXT_XML)
    public String sayXMLHello() {
        return "<?xml version=\"1.0\"?>" + "<hello> Hello Jersey" + "</hello>";
    }

    // This method is called if HTML is request
    @GET
    @Produces(MediaType.TEXT_HTML)
        public String sayHtmlHello() {
            return "<html> " + "<title>" + "Hello Jersey" + "</title>"
                    + "<body><h1>" + "Hello Jersey" + "</body></h1>" + "</html> ";
        }

}
