如何解析對單個JAVA對象的JSON響應

Question

我試圖解析對單個JAVA的JSON響應，該JSON響應包含在另一個JSON數組和簡單字段中。

但是，在嘗試中我可以得到以下結果。

13:07:25,769 INFO  [biz.example.ClentManager] (default task-106) Start findBasicAccountInformation intigartion................................

你有什么主意嗎 ？

Answer 1

我認為這可以總結出以下錯誤：-com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException：無法識別的字段“ StatusCode ”（類biz.spsolutions.edgevantage.workflow.dao.PABCIntegration.ResultBasicAccountInformationDao），未標記為可忽略（5個已知）屬性：“ traceId”，“狀態”，“結果”，“ errorList”，“ statusCode ”]）

字段名稱似乎不匹配，一個以大寫S開頭，另一個以小寫S開頭。 請嘗試更改它。

Answer 2

您可以使用以下方法：

@Data
@AllArgsConstructor
@NoArgsConstructor
@Getter
@Setter
@Builder
public class MyDTO implements Serializable {

    @JsonProperty("id")
    private Long id;


    @JsonProperty("tax_id")
    private Long taxId;

    @JsonProperty("thumbnail")
    private String thumbnail;

    @JsonProperty("short_description")
    private Map<String,Object> shortDescription;

    public static MyDTO buildCatalogProductDTO(MyDomain md) {
    return MyDTO.builder()
            .id(md.getId())
            .taxId(catalogProduct.getTaxId())
            .shortDescription(SerializationUtil.parseJson(md.getShortDescription()))
            .build();
    }

其中SerializationUtil.parseJson在內部使用Gson庫進行轉換。
