使用Gson解析复杂、变态的Json数据（包含中文key）

接口文档：

app配置
接口 client/init

请求数据
json={"uid":"","sid":"","ver":"1",
    "request":{}
}

返回数据
{"ret":0,
    "response":{
        "tag_category":{
            "中国画":{
                "年代":["先秦两汉","战国楚国","魏晋南北","隋唐五代","南宋北宋","元代","明清","近现代","年代不详","其他"],
                "技法":["泼墨","工笔","写意","白描","写生","皴法","没骨","指头画","其他"],
                ...
            },
            "书法":{
                "分类":["书法","碑帖","写本写经","书札文牍","其他"],
                "书体":["篆书","隶书","楷书","草书","行书","其他"],
                ...
            },
            ...
        }
    }
}
备注 tag_category 标签分类

首先自然想到封装成JavaBean。

注意点：

1、内部嵌套的类必须是static的，要不然解析会出错；

2、类里面的属性名必须跟Json字段里面的Key一模一样；

3、因为Json字段里面的Key存在中文，所以必须在相应的字段上使用@SerializedName("中国画")注解，给Key取别名。

4、内部嵌套用{}嵌套的就定义为 public ChinaPicture chinaPicture，用[]括起来的部分是一个List，所以定义为 public List<String> years。

5、如果不想写get和set方法，只需要将字段定义成public。

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

    public static class Response {
        public TagCategory tag_category;
        
        public static class TagCategory {
            
            @SerializedName("中国画")
            public ChinaPicture chinaPicture;
            /**
