未找到 DropWizard MIME 媒体中的错误

Question

我正在创建一个 Web 服务，它采用酒店管理系统的 JSON 对象，如姓名、电子邮件、电话等，并使用 Java 对象提取它。

@Path("/get")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public class AppResource {

    @POST
    public Response setHotel(Hotel hotel) {
        String output = hotel.toString();
        System.out.println(output);
        return Response
                .created(null)
                .build();
    }



}

我的 Java 对象类是

public class Hotel {
    private String hotelName;
    private String email;
    private String phone;
    private String address;
    private String geoLocation;

    // Must have no-argument constructor
    public Hotel()
    {

    }

    public  Hotel(String hotelName,String email,String phone,String address,String geoLocation) {
        this.hotelName = hotelName;
        this.email = email;
        this.phone = phone;
        this.address = address;
        this.geoLocation = geoLocation;
    }


    public String getHotelName() {
        return hotelName;
    }
    public void setHotelName(String hotelName) {
        this.hotelName = hotelName;
    }
    public String getEmail() {
        return email;
    }
    public void setEmail(String email) {
        this.email = email;
    }
    public String getPhone() {
        return phone;
    }
    public void setPhone(String phone) {
        this.phone = phone;
    }
    public String getAddress() {
        return address;
    }
    public void setAddress(String address) {
        this.address = address;
    }
    public String getGeoLocation() {
        return geoLocation;
    }
    public void setGeoLocation(String geoLocation) {
        this.geoLocation = geoLocation;
    }


    @Override
    public String toString() {
        return new StringBuffer(" Hotel Name : ").append(this.hotelName)
                .append(" Email : ").append(this.email)
                .append(" Phone : ").append(this.phone).append(" GeoLocation : ")
                .append(this.geoLocation).toString();
    }

但是当我调用这个网络服务时，我得到了这个错误

我正在使用这个创建请求

Hotel st = new Hotel("Ashish","ashish","9910687844","Delhi","23.32,356");

            ClientConfig clientConfig = new DefaultClientConfig();

            clientConfig.getFeatures().put(
                    JSONConfiguration.FEATURE_POJO_MAPPING, Boolean.TRUE);

            Client client = Client.create(clientConfig);

            WebResource webResource = client
                    .resource("http://localhost:8080/get");

            ClientResponse response = webResource.accept("application/json")
                    .type("application/json").post(ClientResponse.class, st);

            if (response.getStatus() != 200) {
                throw new RuntimeException("Failed : HTTP error code : "
                        + response.getStatus());
            }

            String output = response.getEntity(String.class);

            System.out.println("Server response .... \n");
            System.out.println(output);

在您的请求对象上添加注释@JsonSerialize，即Hotel。 Javadoc link.
