邮递员-在邮递上发送图像文件和json

Question

public class NewShipmentDto implements Serializable {
  private String description;
  private Long senderId;
  private Long receiverId;
  private byte[] packageImage;
  private CommissionPaidBy commissionPaidBy;
  private Long senderPaymentMethod;
  private LocationDto senderLocation;
  private LocationDto receiverLocation;

// + constructors and gets/sets
}

{
    "description":"Libros",
    "senderId":1,
    "receiverId":1,
    "commissionPaidBy":"BOTH",
    "senderPaymentMethod":1,
    "senderLocation":
    {
        "latitud":100,
        "longitud":100
    },
    "receiverLocation":
    {
        "latitud":100,
        "longitud":100
    }
}

"receiverLocation":
{
    "latitud":100,
    "longitud":100
}

这是我的POST方法，我还没有添加读取文件的逻辑：

@POST
@Consumes({MediaType.APPLICATION_JSON})
@Produces({MediaType.APPLICATION_JSON})
public Response addShipment(String shipment) throws EnviosYaException {
    Gson gson = new Gson();
    NewShipmentDto newShipmentDto = gson.fromJson(shipment, NewShipmentDto.class);
    NewShipmentResponseDto response = shipmentServices.addShipment(newShipmentDto);
    return Response.ok(gson.toJson(response)).build();
}

如果有必要，我可以更改json的结构，以避免出现嵌套的json，但我想先知道这是否可行。谢谢

看起来您将JAX-RS用于REST API。对于您的用例，Multipart/Format-DataContent-Type更合适。请看一下这个JAX-RS问题。

或

如果希望保持JSON结构不变，可以将base64编码的数据存储在image字段的字符串中。模型看起来像。

public class NewShipmentDto implements Serializable {
  private String description;
  private Long senderId;
  private Long receiverId;
  private String encodedPackageImage;
  private CommissionPaidBy commissionPaidBy;
  private Long senderPaymentMethod;
  private LocationDto senderLocation;
  private LocationDto receiverLocation;

  // + constructors and gets/sets
}
