我正在为Apple Push Notification Service解析类到JSON。所以我有一个acme类，并希望在最终的JSON中附加额外的，可选的和动态的{
"aps": {
"alert": {
"body": "body",
"title": "title"
},
"badge": 123,
"category": "category"
},
"acme": {
"1": "1",
"value1": "value1"
}
}
属性。这意味着我想转换下面的Jackson输出...
{
"aps": {
"alert": {
"body": "body",
"title": "title"
},
"badge": 123,
"category": "category"
},
"acme-1": "1",
"acme-value1": "value1"
}
对此...
acme-我已成功为@JsonNaming()的密钥添加前缀@Value
@Builder
@JsonInclude(JsonInclude.Include.NON_NULL)
// need a serializer to move up properties in Acme by one level
// @JsonSerialize(using = NewSerializer.class)
public class ApnsPayload {
private Aps aps;
private Acme acme;
@JsonNaming(AcmeNamingStrategy.class) // add prefix acme-
public interface Acme {
}
@Value
@Builder
@JsonInclude(JsonInclude.Include.NON_NULL)
public static class Aps {
private Alert alert;
private Integer badge;
private String sound;
@JsonProperty("content-available")
private Integer contentAvailable;
private String category;
@JsonProperty("thread-id")
private String threadId;
@Value
@Builder
@JsonInclude(JsonInclude.Include.NON_NULL)
public static class Alert {
private String title;
private String body;
@JsonProperty("title-loc-key")
private String titleLocalizationKey;
@JsonProperty("title-loc-args")
private List<String> titleLocalizationArgs;
@JsonProperty("action-loc-key")
private String actionLocalizationKey;
@JsonProperty("loc-key")
private String localizationKey;
@JsonProperty("loc-args")
private List<String> localizationArgs;
@JsonProperty("launch-image")
private String launchImage;
}
}
}
，但我无法将这些属性移动一级。请帮忙，谢谢！

答案 0 :(得分：1)
LOL，我在发布此问题后2分钟找到答案。我需要的只是Jackson Unwrapping Feature，方法是将@JsonUnwrapped添加到要解包的属性中。
@JsonUnwrapped
private Acme acme;
