ElasticSearch返回不同的type的序列化

总体思路是：

利用json序列化的别名方法，反序列化到不同的字段上；

因为别名方法不支持多个别名，所以不得不根据不同的type，定义了多套适配内容。

最终在属性上进行选择。

本示例ElasticSearch返回的json串形如：

{

    "took": ,
    "timed_out": false,
    "_shards": {
        "total": ,
        "successful": ,
        "failed":
    },
    "hits": {
        "total": ,
        "max_score": 3.4698925,
        "hits": [
            {
                "_index": "user",
                "_type": "userinfo",
                "_id": "",
                "_score": 3.4698925,
                "_source": {
                    "uid": ,
                    "level":
                }
            }
            ,
            {
                "_index": "user",
                "_type": "good",
                "_id": "",
                "_score": 0.06378032,
                "_source": {
                    "id": ,
                    "name": "good luck"
                }
            }
        ]
    }
