У меня есть следующий проект ..не сделано или написано мной, и я пытаюсь решить ошибку с этим проектом.В основном, когда я пытаюсь создать поездку "/ api / ride", используя приведенный ниже общий запрос, я всегда получаю неправильные данные, сохраняемые в базу данных.

Запрос: 

{
  "distance": 20,
  "driver": {
    "email": "testdriver@test.com",
    "id": 1,
    "name": "test driver",
    "registrationNumber": "7895612313"
  },
  "endTime": "2018-10-07T18:46:19",
  "id": 100,
  "rider": {
    "email": "csfragstatest@test.com",
    "id": 1,
    "name": "csfragstatest",
    "registrationNumber": "54564897456"
  },
  "startTime": "2018-10-06T18:46:19"
}

Ответ: 

{
  "id": 1,
  "startTime": "2018-10-06T18:46:19",
  "endTime": "2018-10-07T18:46:19",
  "distance": 20,
  "driver": {
    "id": 1,
    "name": "csfragstatest",
    "email": "csfragstatest@test.com",
    "registrationNumber": "465123167"
  },
  "rider": {
    "id": 1,
    "name": "csfragstatest",
    "email": "csfragstatest@test.com",
    "registrationNumber": "465123167"
  }
}

Пожалуйста, помогите мне, если я ошибаюсь здесь .... У меня нет большой идеи, используя пружинуjpa и hibernate ... Я так растерялся, ломая голову против этого .. Любая помощь приветствуется ... Заранее спасибо!
