java - Spring 启动: Json Response is not Mapping to Entity

Question

我正在尝试通过安全的 RESTful API 映射我使用的 Json 响应；但是，由于某种原因，映射没有正确发生，因为我不断收到 NULL 响应而不是填充的对象。

这是我的实体:

@JsonTypeName("order")
@JsonTypeInfo(include = JsonTypeInfo.As.WRAPPER_OBJECT ,use = JsonTypeInfo.Id.NAME)
public class Order {

    @JsonProperty("id")
    private long customerd;

    @JsonProperty("email")
    private String customeEmail;


    public long getCustomerd() {
        return customerd;
    }

    public void setCustomerd(long customerd) {
        this.customerd = customerd;
    }


    public String getCustomeEmail() {
        return customeEmail;
    }

    public void setCustomeEmail(String customeEmail) {
        this.customeEmail = customeEmail;
    }
}

这是我的服务方法:

   public Order orderDetails (@RequestBody Order order){

       String username = "username";
       String password = "password";
       HttpHeaders headers = new HttpHeaders();
       headers.setBasicAuth(username, password);

       // request url
       String url = "https://test.myshopify.com/admin/orders/2013413015655.json";

       RestTemplate restTemplate = new RestTemplate();

       HttpEntity request = new HttpEntity(headers);

        ResponseEntity<Order> response = restTemplate.exchange(
           url, HttpMethod.GET, request, Order.class);

       return order;
   }

这是我的 Controller 方法:

    @GetMapping("/orderdetails")
    @ResponseStatus(HttpStatus.FOUND)
    public Order getBasicAut(Order order){
        return basicAuth.orderDetails(order);
    }

您应该配置 REST 以生成 JSON 内容

@GetMapping(path = "/orderdetails", produces = {MediaType.APPLICATION_JSON_VALUE})

具体来说，下面的代码运行良好

@RestController
public class JsonController {

  @GetMapping(path = "/orderdetails", produces = {MediaType.APPLICATION_JSON_VALUE})
  @ResponseStatus(HttpStatus.FOUND)
  public Order sendJsonBack() {
    final Order order = new Order();
    order.setCustomerd(123L);
    order.setCustomeEmail("mail@gmail.com");
    return order;
  }
}


@Data
class Order implements Serializable {

  private static final long serialVersionUID = -4258392267221190600L;

  @JsonProperty("id")
  private long customerd;

  @JsonProperty("email")
  private String customeEmail;

}
