Java 如何结合Jersey、JSON和Spring

我有一个测试web服务项目，我使用REST（Jersey）+JSON+Spring。问题是我不知道如何将它们结合在一起。例如，我有一个

组件
类，它可以与数据库一起工作：

@Component
@Path("/payment")
public class PaymentService {

    @Autowired
    TransactionBo transactionBo;

    @GET
    @Path("/get")
    public Response savePayment() {
        String result = transactionBo.save();

        return Response.status(200).entity(result).build();
    }
}

我还有一个JSON类，它获取并返回JSON中的对象：

@Path("/json")
public class JSONService {

    @GET
    @Path("/get")
    @Produces(MediaType.APPLICATION_JSON)
    public Track getTrackInJSON() {

        Track track = new Track();
        track.setTitle("Enter Sandman");
        track.setSinger("Metallica");

        return track;
    }

    @POST
    @Path("/post")
    @Consumes(MediaType.APPLICATION_JSON)
    public Response createTrackInJSON(Track track) {
        System.out.println("In post");

        String result = "Track saved : " + track;
        return Response.status(201).entity(result).build();
    }
}

现在我正试图把它们结合起来。我想从DB中获取数据并将其转换为JSON，然后在响应中返回：

@Component
@Path("/hotel")
public class HotelWs {
@Autowired
private HotelService hotelService;

@GET
@Path("/get/{hotelId}")
@Produces(MediaType.APPLICATION_JSON)
public Hotel getHotel(@PathParam("hotelId") long id) {
    Hotel hotel = hotelService.findById(id);
    if (hotel == null) {
        hotel = new Hotel();
        hotel.setId(1);
        hotel.setName("Name");
        hotel.setType("Type");
    }
    return hotel;
}

当我使用最后一个组合启动项目时，我得到以下错误：

您使用的是非常旧的Jersey版本（2011年6月发布的1.8版），很可能是下载了旧版本的Spring。有一个新的（2.13是最近的一个）。查看此站点的文档和示例：
为什么不使用SpringDataREST？&好吧，因为jersey非常受欢迎，不能再说了，因为我以前从未使用过spring数据rest：）好吧，我不想批评你的堆栈。也许这个答案可以帮助你：只是为了确认一下，你使用的是什么JDK版本？我使用的是JDK 8，但我认为，问题在于servlet（jersey完成了这项工作）和Spring之间存在冲突，我另外添加了Spring，看起来，当我尝试使用不带注释组件的类时，Spring并没有“看到”它，但当我添加组件时，春天与泽西相冲突。我想我必须更改我的pom文件，但我不知道如何更改。
