解析JSON并将其保存在H2数据库中

Question

我具有以下JSON，我需要解析它们并将其持久化到H2数据库。我正在努力理解并创建具有适当注释的基础类/实体的结构。我想知道是否有人建议我这样做。

{
  "teams": [
    {
      "positions": [
        {
          "alert": false,
          "altitude": 18,

        },
        {

          "type": "automatic",

          "sogKnots": 0,

          "dtfNm": 2689.867,

          "gpsAtMillis": 1511085600000,
          "sogKmph": 0
        },
        {
          "alert": false,
          "altitude": 10,
          "type": "automatic",

          "cog": 151,
          "dtfNm": 2689.867,
          "txAt": "2017-11-19T09:00:16Z",
          "longitude": -15.42635,
          "latitude": 28.12884,
          "gpsAtMillis": 1511082006000,
          "sogKmph": 0
        }
      ],
      "marker": 222,
      "name": "Rock 7",
      "serial": 6251
    }
  ],
  "raceUrl": "test2017"
}

您能为实体推荐一种结构来解析它并保存到H2数据库中吗？

Answer 1

以下DTO结构应该可以正常工作。我添加了几个字段

class Position {

    public boolean alert;
    public String type;
    ...

}

class Teams {

    public String marker;
    public String name;
    public Integer serial;

    public List<Position> positions;

}


class MainDTO {

    public List<Teams> teams;
    public String raceUrl;

}
