使用Gson解析復雜、變態的Json數據（包含中文key）

接口文檔：

app配置
接口 client/init

請求數據
json={"uid":"","sid":"","ver":"1",
    "request":{}
}

返回數據
{"ret":0,
    "response":{
        "tag_category":{
            "中國畫":{
                "年代":["先秦兩漢","戰國楚國","魏晉南北","隋唐五代","南宋北宋","元代","明清","近現代","年代不詳","其他"],
                "技法":["潑墨","工筆","寫意","白描","寫生","皴法","沒骨","指頭畫","其他"],
                ...
            },
            "書法":{
                "分類":["書法","碑帖","寫本寫經","書札文牘","其他"],
                "書體":["篆書","隸書","楷書","草書","行書","其他"],
                ...
            },
            ...
        }
    }
}
備注 tag_category 標簽分類

首先自然想到封裝成JavaBean。

注意點：

1、內部嵌套的類必須是static的，要不然解析會出錯；

2、類里面的屬性名必須跟Json字段里面的Key一模一樣；

3、因為Json字段里面的Key存在中文，所以必須在相應的字段上使用@SerializedName("中國畫")注解，給Key取別名。

4、內部嵌套用{}嵌套的就定義為 public ChinaPicture chinaPicture，用[]括起來的部分是一個List，所以定義為 public List<String> years。

5、如果不想寫get和set方法，只需要將字段定義成public。

public class JsonBean {
    public int ret;
    public Response response;

    public static class Response {
        public TagCategory tag_category;
        
        public static class TagCategory {
