Question

在Spring中遇到了post方法的问题。当我尝试将对象发布到数据库时，客户端应用程序已挂起，我需要终止它。带卷曲的物体正常工作。我正在获取日志：

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"]

客户端：

积分班：

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;
}

发布功能：

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

服务器端：

控制器：

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

积分等级：

@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;
}
}

在AWS服务器上检查日志，当我尝试在客户端上发布对象时，会调用很多get方法：
