如何解析对单个JAVA对象的JSON响应

Question

I tried to parse a JSON response to a single JAVA Object.This JSON response included with another JSON arrays and simple fields.

However I could get following result in my attempts.

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

Do you have any idea ?

Answer 1

I think this sums up the error:- com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field " StatusCode " (class biz.spsolutions.edgevantage.workflow.dao.PABCIntegration.ResultBasicAccountInformationDao), not marked as ignorable (5 known properties: "traceId", "status", "result", "errorList", " statusCode "])

seems the field names do not match, one starts with capital S and the other small s. Please try changing it.

Answer 2

You can use some thing like this:

@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();
    }

where SerializationUtil.parseJson is internally using Gson library for conversion.
