How to correctly map huge json file to Java (pojo)?

Thanks a lot for your advices. Implemented in the following way: I used JsonAnySetter annotation to set all fields instead creating pojo with all of the possible fields. Here is my Dto's

FeatureDto

@Getter
@ToString
public class FeatureDto {

  @JsonProperty("type")
  private String type;
  @JsonProperty("geometry")
  private GeometryDto geometry;
  @JsonProperty("properties")
  private PropertiesDto properties;

}

PropertiesDto

@Getter
@ToString
public class PropertiesDto {

  private List<FieldDto> fieldDtos = new ArrayList<>();

  @JsonAnySetter
  public void setProperties(String code, Object value)
  {

    if(value instanceof ArrayList) {
      ArrayList<Object> list = (ArrayList<Object>) value;
      StringBuffer stringBuffer = new StringBuffer();
      list.forEach(o -> stringBuffer.append(o).append(", "));
      fieldDtos.add(new FieldDto(code, stringBuffer.toString()));
      return;
    }

    fieldDtos.add(new FieldDto(code, value.toString()));
  }

}

FieldDto

@Data
@ToString
@JsonIgnoreProperties(ignoreUnknown = true)
@AllArgsConstructor
public class FieldDto {

  @JsonProperty("code")
  private String code;
  @JsonProperty("value")
  private String value;

}

Here is the json source:
