后台接收嵌套json

{     "topic":"/sys/mission",     "data":{"code": "10003",         "param": { "missionID":"0b9d198a4a0c4c5dbcbde791957531ef",         "name": "娃哈哈线",          "autoFlightSpeed": 8,         "gotoFirstWaypointMode": 1,         "finishAction": 1,          "headingMode": 1,          "flightPathMode": 1,         "homePointLatitude": 23.222,         "homePointLongitude": 113.22,          "clearHomeLocation": false,         "executeTime": "N/A",          "backupLandingLatitude": 23.2223,         "backupLandingLongitude": 113.3332,         "backupLandingAltitude": 10 } } }

有这种类似的嵌套json建议传输到后端后使用map接收，加@RequestBody注释，然后获取相应的数据，使用Bean不好接受
