在IntelliJ/Tomcat上使用Jersey运行REST with Java(JAX-RS)

我正在OSX上的IntelliJ中尝试执行以下教程：

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

在Eclipse中运行代码时，一切都很好。但是在IntelliJ中运行代码会为相同的URI提供404。

该程序应该在Apache Tomcat Server 8.0.20上运行。

我已经完全完成了教程中所写的内容，但我不明白为什么它在IntelliJ中不起作用。我找了好几天了，终于找到了解决办法。

部署中似乎出现了问题，因为index.jsp运行良好。

希望有人能帮我。

程序代码：

班级你好：

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> ";
        }
}
