fastjson複雜json轉換為java對象

最近從redis裡面取資料的時候發現有一個結構時較為複雜的json，開始還想着要用反射機制将json轉換為對象。最後經過查閱很多文檔fastjson性能很好，經過很多實驗終于将json轉換為對應java bean了。

json：

{
  "areaInit": false,
  "corpId": 211,
  "inCustomAreaList": [
    {
      "areaAcReage": 0.0,
      "areaId": 90,
      "corpId": 1,
      "createdUserId": 0,
      "inlayer": 0,
      "isValid": 1,
      "modifiedUserId": 0,
      "orgId": 0,
      "range": 0,
      "shareMode": 0,
      "typeId": 0
    }
  ],
  "preGPSData": {
    "VehicleID": 2762,
    "statusStr": "ACC關,3D定位,天線正常",
    "GpsTime": 1626008713000,
    "Wid": "14548985459",
    "Lon": 113.5479520,
    "Lat": 23.1982880,
    "Speed": 0,
    "Direction": 145,
    "Odometer": 388058.50,
    "Height": 39,
    "ACCStatus": 1,
    "LineStatus": 1,
    "LoStatus": 3,
    "Status": "",
    "UpdateDate": 1626008714000
  },
  "vehicleID": 2763
}
           

轉換代碼

JSONObject parse = JSON.parseObject(parseValue);
VehicleTrajectoryDTO vehicleTrajectoryDTO = parse.toJavaObject(VehicleTrajectoryDTO.class);
           

隻要兩行就搞定。
