JSON dynamische Feldnamen mit Jackson

Question

Ich verwende eine API, die eine swagger.yaml davon liefert ich folgende Klasse erzeugt:

@ApiModel(description="the paginated history of the specification attributes values") 
public class SpecificationHistoryResponse { 

    @ApiModelProperty(example = "null", value = "the array of historic values is named with the specification attributes key") 
    private List<SpecificationResponse> key = new ArrayList<SpecificationResponse>(); 
    @ApiModelProperty(example = "null", value = "") 
    private Pagination pagination = null; 

/** 
    * the array of historic values is named with the specification attributes key 
    * @return key 
    **/ 
    public List<SpecificationResponse> getKey() { 
    return key; 
    } 

    public void setKey(List<SpecificationResponse> key) { 
    this.key = key; 
    } 

    public SpecificationHistoryResponse key(List<SpecificationResponse> key) { 
    this.key = key; 
    return this; 
    } 

    public SpecificationHistoryResponse addKeyItem(SpecificationResponse keyItem) { 
    this.key.add(keyItem); 
    return this; 
    } 

/* ... */ 
} 

Verwendung der API einen SpecificationHistoryRespone für eine bestimmte „Spezifikation“ liefert folgende JSON zu beantragen:

{ 
    "specification_key": [ 
    { 
     "value": "0.02242", 
     "source_timestamp": "2017-08-09T13:10:04.177Z" 
    }, 
    { 
     "value": "0.0124", 
     "source_timestamp": "2017-08-11T13:16:04.177Z" 
    } 
    /*...*/ 
    ], 
    "pagination": { 
    /*...*/ 
    } 
} 

die JacksonJsonProvider Verwendung kann ich nicht specification_key bekommen, wie es immer einen Wert key deserialisieren versucht, die es nicht gibt.

Okay, die automatisch erstellt Code ganz einige Bearbeitung benötigt und soll wie folgt aussieht mit dynamischen Feldnamen zu arbeiten:

@ApiModel(description="the paginated history of the specification attributes values") 
public class SpecificationHistoryResponse { 

    @ApiModelProperty(example = "null", value = "the array of historic values is named with the specification attributes key") 
    @JsonAnySetter 
    private Map<String, List<SpecificationResponse>> key = new HashMap<>(); 
    @ApiModelProperty(example = "null", value = "") 
    private Pagination pagination = null; 

/** 
    * the array of historic values is named with the specification attributes key 
    * @return key 
    **/ 
    public Map<String, List<SpecificationResponse>> getKey() { 
    return key; 
    } 

    public void setKey(Map<String, List<SpecificationResponse>> key) { 
    this.key = key; 
    } 

    public SpecificationHistoryResponse key(Map<String, List<SpecificationResponse>> key) { 
    this.key = key; 
    return this; 
    } 
/* ... */ 
}
