pojo用无效的java名称解析gson

Question

我正在使用google-api-client的youtube json:

{
    "apiVersion": "2.0",
    "data": {
        "updated": "2011-01-05T13:48:33.146Z",
        "totalItems": 4,
        "startIndex": 1,
        "itemsPerPage": 1,
        "items": [
            {
                "id": "YfUzMkAlOBI",
                "uploaded": "2010-12-29T16:50:47.000Z",
                "updated": "2010-12-29T16:50:47.000Z",
                "uploader": "devandroidcs",
                "category": "Entertainment",
                "title": "Teste 2",
                "description": "Description do teste2",
                "tags": [
                    "mobile"
                ],
                "thumbnail": {
                    "sqDefault": "http://i.ytimg.com/vi/YfUzMkAlOBI/default.jpg",
                    "hqDefault": "http://i.ytimg.com/vi/YfUzMkAlOBI/hqdefault.jpg"
                },
                "player": {
                    "default": "http://www.youtube.com/watch?v\u003dYfUzMkAlOBI&feature\u003dyoutube_gdata_player",
                    "mobile": "http://m.youtube.com/details?v\u003dYfUzMkAlOBI"
                }
.
.
.
}

此时我应该在我的parse java类中创建一个名为default的字段名.已完成此解析与其他字段一起工作,问题是,默认是私有java名称,所以我无法调用变量默认值.

我怎么能管理呢？

Answer 1

我相信您的答案在于JSON字段命名支持:

Gson支持一些预定义的字段命名策略,以将标准Java字段名称(即以小写字母开头的驼峰名称---"sampleFieldNameInJava")转换为Json字段名称(即sample_field_name_in_java或SampleFieldNameInJava).

例如,参见以下示例:

private class SomeObject {
  @SerializedName("custom_naming") private final String someField;
  private final String someOtherField;

  public SomeObject(String a, String b) {
    this.someField = a;
    this.someOtherField = b;
  }
}

所以你应该能够将字段映射定义为默认值,如下所示:

@SerializedName("default")
private final String someOtherNameThanDefault;
