jackson JsonInclude Non_Null不忽略对嵌套对象属性的处理

公共类TrackInformation扩展了AbstractRecord{

@JsonInclude(JsonInclude.Include.NON_NULL)
public class Flight implements Serializable {

    private TrackInformation trackInformation;

    private MiscData miscData;

    private CargoItems cargoItems;

}



Controller class

  

 @RequestMapping(value = "/getFlightByKey", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE)
public Flight getFlightByKey(@RequestBody @Valid final FlightInfoRequestDTO request)throws NoDataFoundException  {
    return flightInfoAppService.getFlightByKey(request.getKey());
}

}

公共抽象类AbstractRecord实现了可序列化{

}

现在，返回的flight对象具有嵌套对象的空字段。如何忽略嵌套对象中的空字段

---

hashCode和equals是否在TrackInformation中重写。

您应该在每个嵌套类上添加

@JsonInclude（JsonInclude.Include.NON_NULL）

，以忽略嵌套类的NULL值属性

private static final long serialVersionUID = -5226745652646434627L;

private String sourceFacility;

private ComputerID computerID;

private String sourceTimeStamp;

private Double latitude;

private Double longitude;

private ReportedAltitude reportedAltitude;

private Integer speed;

---

您还应该在每个嵌套类上添加

@JsonInclude（JsonInclude.Include.NON\u NULL）

，以忽略嵌套类的NULL值属性

private static final long serialVersionUID = -5226745652646434627L;

private String sourceFacility;

private ComputerID computerID;

private String sourceTimeStamp;

private Double latitude;

private Double longitude;

private ReportedAltitude reportedAltitude;

private Integer speed;
