JAVA json schema 2 POJO

I have to create a REST response. The data is json formatted, and must be structured as the following :

{
    "device_id" : { "downlinkData" : "deadbeefcafebabe"}
}

"device_id" has to replaced for the DeviceId, for instance:

{
    "333ee" : { "downlinkData" : "deadbeefcafebabe"}
}

or

{
    "9886y" : { "downlinkData" : "deadbeefcafebabe"}
}

I used http://www.jsonschema2pojo.org/ and this is the result:

@JsonInclude(JsonInclude.Include.NON_NULL)
@JsonPropertyOrder({
"device_id"
})
public class DownlinkCallbackResponse {

    @JsonProperty("device_id")
    private DeviceId deviceId;
    @JsonIgnore
    private Map<String, Object> additionalProperties = new HashMap<String, Object>();

    @JsonProperty("device_id")
    public DeviceId getDeviceId() {
    return deviceId;
    }

    @JsonProperty("device_id")
    public void setDeviceId(DeviceId deviceId) {
    this.deviceId = deviceId;
    }

    @JsonAnyGetter
    public Map<String, Object> getAdditionalProperties() {
    return this.additionalProperties;
    }

    @JsonAnySetter
    public void setAdditionalProperty(String name, Object value) {
    this.additionalProperties.put(name, value);
    }

}

and 

@JsonInclude(JsonInclude.Include.NON_NULL)
@JsonPropertyOrder({
"downlinkData"
})
public class DeviceId {

    @JsonProperty("downlinkData")
    private String downlinkData;
    @JsonIgnore
    private Map<String, Object> additionalProperties = new HashMap<String, Object>();

    @JsonProperty("downlinkData")
    public String getDownlinkData() {
    return downlinkData;
    }

    @JsonProperty("downlinkData")
    public void setDownlinkData(String downlinkData) {
    this.downlinkData = downlinkData;
    }

    @JsonAnyGetter
    public Map<String, Object> getAdditionalProperties() {
    return this.additionalProperties;
    }

    @JsonAnySetter
    public void setAdditionalProperty(String name, Object value) {
    this.additionalProperties.put(name, value);
    }

}

But based on this POJOs I can't set the deviceID:

DownlinkCallbackResponse downlinkCallbackResponse = new DownlinkCallbackResponse ();

        DeviceId deviceId = new DeviceId();
        deviceId.setDownlinkData(data);     
        downlinkCallbackResponse.setDeviceId(deviceId);

        return new ResponseEntity<>(downlinkCallbackResponse, HttpStatus.OK);

get following json string 

 { "downlinkData" : "deadbeefcafebabe"}

create json object ( Lib : java-json.jar )

 JSONObject obj = new JSONObject();

put above json string into json object.

 obj.put("333ee", jsonString);

that will create following json string

{

"333ee" : { "downlinkData" : "deadbeefcafebabe"}
}

I hope this will help you. :-)
