java - 启动 HTTP 服务器时未找到 Jersey ResourceConfig

Question

我已经编写了一些服务来通过 REST 提供 latex 文档的编译，但现在它已经完成了，我陷入了困境。 :/

在开发它时，我使用 TestNG 和 RestAssured 对其进行了测试，它的工作方式非常神奇，但现在我尝试单独运行它。我不太确定问题出在哪里，所以我尝试粘贴所有重要的内容并进行一些解释。

问题是，当我让服务器在主方法中单独运行时，会出现以下异常。 (额外问题:我什至可以以这种方式运行它，或者如果必须将其部署在应用程序服务器上作为 war，它也可以从命令行作为 jar 运行，只需使用 java -jar x.jar 调用它吗？)

控制台输出

这就是服务器实例化的类的样子:

RestServer.java

public class RestServer {

    static final URI BASE_URI = URI.create("http://localhost:8080/");
    final HttpServer httpServer;

    public RestServer() {
        final ResourceConfig resourceConfig = new ResourceConfig(JobService.class, JobFileService.class, LatexEnvironmentService.class, MultiPartFeature.class);
        httpServer = GrizzlyHttpServerFactory.createHttpServer(BASE_URI, resourceConfig);
        System.out.println(String.format("Jersey app started with WADL available at %sapplication.wadl\nTry out %sjobs or %slatex/environments",
                BASE_URI, BASE_URI, BASE_URI));
    }

    public void shutdown() {
        httpServer.shutdownNow();
    }

    public static void main (String[] args){
        RestServer restServer = new RestServer();
        try {
            System.in.read();
        } catch (IOException ex) {
            Logger.getLogger(RestServer.class.getName()).log(Level.SEVERE, null, ex);
        }
        restServer.shutdown();
    }
}

我只是在闲逛，但也许有一个问题，我只使用注释而没有实际的 web.xml？

JobService.java

@Path("/jobs")
public class JobService {

    private final RequestHandler requestHandler = new RequestHandler();

    @POST
    @Produces(MediaType.APPLICATION_JSON)
    @Consumes(MediaType.APPLICATION_FORM_URLENCODED)
    public Response createJob() {
        return requestHandler.handleCreateJob();
    }

    @GET
    @Path("{jobId}/compile/{latexEnvironment}")
    @Consumes(MediaType.APPLICATION_FORM_URLENCODED)
    @Produces(MediaType.APPLICATION_JSON)
    public Response compile(@PathParam("jobId") final Long jobId, @PathParam("latexEnvironment") final String latexEnvironment){ //, @Suspended final AsyncResponse asyncResponse) {
        return requestHandler.handleCompile(jobId, latexEnvironment);
    }

这就是 pom.xml 的样子:

我很高兴有人看到这个问题并大肆讨论，谢谢大家! (也感谢任何提示或其他主题的链接，部署此类东西的正确做法是什么。)

感谢 @andrei-i 让我走上了正确的道路，我发现所有 Jersey 依赖项的范围都是错误的。设置为假设它们必须在测试时存在，但在运行时不存在。我只是删除了所有这些范围，它就起作用了。天哪!
