ジャクソンのJava EE WS - XMLが空ですが、JSONは私がRESTサービスで露光てるPOJOを持って

Question

すべてのフィールドがあります。

@XmlRootElement 
public class Field implements Serializable{ 
    /** 
    * 
    */ 
    @JsonIgnore 
    private static final long serialVersionUID = 1L; 

    FieldType fieldType; 

    String name; 

    Object deafultValue; 

    Map<String, String> choices; 

    boolean required; 

    public Field(){} 

    @JsonCreator 
    public Field(@JsonProperty("fieldType") FieldType fieldType, String name, Object deafultValue, Map<String, String> choices, boolean required) { 
     super(); 
     this.fieldType = fieldType; 
     this.name = name; 
     this.deafultValue = deafultValue; 
     this.choices = choices; 
     this.required = required; 
    } 

    @JsonProperty 
    public FieldType getFieldType() { 
     return fieldType; 
    } 

    @Override 
    public String toString() { 
     return "Field [fieldType=" + fieldType + ", name=" + name + ", deafultValue=" + deafultValue + ", choices=" 
       + choices + ", required=" + required + "]"; 
    } 

    public String getName() { 
     return name; 
    } 

    public Object getDeafultValue() { 
     return deafultValue; 
    } 

    public Map<String, String> getChoices() { 
     return choices; 
    } 

    public boolean isRequired() { 
     return required; 
    } 

} 

私が露出されているオブジェクトの数を持っているが、ほとんどのそれらは@Entity注釈でマークされており、正常に動作します。ここで

は私のWebサービスのコードです：

@GET 
    @Path("search-fields") 
    @Produces({"application/xml", "application/json"}) 
    public List<Field> getSearchFields(){ 
     L.debug("Getting Actor search fields: {}", new Actor().getSearchFields()); 
     return new Actor().getSearchFields(); 
    } 

ログメッセージは、データがあることを言う：

DEBUG ActorsFacadeREST - 俳優の検索フィールドを取得：[フィールド[FIELDTYPE = INPUT 、name = Name、deafultValue = null、choices = null、required = true]]

私はJSONを照会：

$ curl -i -H "Accept: application/json" -H "Content-Type: application/json" -X GET http://localhost:8080/actor-service/webresources/entities.actors/search-fields/ && echo "" 
HTTP/1.1 200 OK 
Connection: keep-alive 
X-Powered-By: Undertow/1 
Server: WildFly/10 
Content-Type: application/json 
Content-Length: 88 
Date: Sun, 20 Mar 2016 13:44:46 GMT 

[{"fieldType":"INPUT","name":"Name","deafultValue":null,"choices":null,"required":true}] 

私はXMLを求める：

$ curl -i -H "Accept: application/xml" -H "Content-Type: application/json" -X GET http://localhost:8080/actor-service/webresources/entities.actors/search-fields/ && echo "" 
HTTP/1.1 200 OK 
Connection: keep-alive 
X-Powered-By: Undertow/1 
Server: WildFly/10 
Content-Type: application/xml 
Content-Length: 88 
Date: Sun, 20 Mar 2016 13:46:47 GMT 

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><collection><field/></collection> 

はなぜJSONオブジェクトのデータを持っていないが、XMLは空ですか？ @XmlRootElement以外のXMLアノテーション（私には見つからない）がありますか？

私は正常に動作する、以下の豆持って

を追加するように編集：私はあなたにも@XmlElementであなたのフィールドに注釈を付けるために持っていると思う

public class Actor implements Serializable, HasImage, Searchable<Actor> { 
    private static final transient Logger L = LoggerFactory.getLogger(Actor.class); 
    private static final long serialVersionUID = 1L; 

    private Long id; 

    private String eid; 

    private String name; 

    private String status; 

    private String reportsToEid; 

    private String email; 

    String imageLocation; 


    PathType pathType; 

    public Actor() { 
     L.debug("Actor created with default constructor"); 
    } 

    @JsonCreator 
    public Actor(@JsonProperty("id") Long id, @JsonProperty("eid") String eid, @JsonProperty("name")String name, 
      @JsonProperty("status") String status, @JsonProperty("reportsToId") String reportsToEid, 
      @JsonProperty("email") String email, @JsonProperty("imageLocation")String imageLocation, 
      @JsonProperty("pathType") PathType pathType) { 
     super(); 
     L.debug("Actor created with JsonCreator marked constructor"); 
     this.id = id; 
     this.eid = eid; 
     this.name = name; 
     this.status = status; 
     this.reportsToEid = reportsToEid; 
     this.email = email; 
     this.imageLocation = imageLocation; 
     this.pathType = pathType; 
    }
