Spring MVC Post не работает, клиент зависает - PullRequest

У меня проблема с методом записи в Spring. Когда я пытаюсь отправить объект в базу данных, клиентское приложение зависает, и мне нужно прекратить его. Размещение объекта с помощью curl работает нормально. Я получаю журнал:

Caused by: com.fasterxml.jackson.databind.JsonMappingException: Infinite recursion (StackOverflowError) (through reference chain: java.util.ArrayList[0]->dareq.Point["points"]->java.util.ArrayList[0]->dareq.Point["points"]->java.util.ArrayList[0]->dareq.Point["points"]->java.util.ArrayList[0]->dareq.Point["points"]

Клиентская сторона:

Класс балла:

public class Point {
private Long id;
private List<String> bssid = new ArrayList<>();
private List<Double> rssi = new ArrayList<>();
private double x;
private double y;

public Point()
{

}

public Point(Long id, List<String> bssid, List<Double> rssi, double x, double y){
    this.id = id;
    this.bssid = bssid;
    this.rssi = rssi;
    this.x = x;
    this.y = y;
}

Почтовая функция:

public void postPoint()
{
    RestTemplate restTemplate = new RestTemplate();
    restTemplate.postForObject("http://localhost:5000/points", this, this.getClass());
}

Сторона сервера:

Контроллер:

@PostMapping("/points")
Points newPoints(@RequestBody Points newPoints){
    return repository.save(newPoints);
}

Класс очков:

@Data
@Entity
public class Points {

private @Id @GeneratedValue Long id;
@Column
@ElementCollection
private List<String> bssid;
@Column
@ElementCollection
private List<Double> rssi;
private double x;
private double y;

Points (){
};

Points(List<String> bssid, List<Double> rssi, double x, double y){
    this.bssid=bssid;
    this.rssi=rssi;
    this.x=x;
    this.y=y;
}
}

Проверка журналов на сервере AWS, когда я пытаюсь опубликовать объект на клиенте, вызываются многие методы get:
