在spring-boot中，使用JPA将数据作为多边形存储在坐标数组列表中

@Entity
public class Polygon {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @ElementCollection
    private List<Point> coordinates;

    // 其他属性和方法...
}

@Embeddable
public class Point {
    private double x;
    private double y;

    // 构造函数、getter和setter方法...
}

@Repository
public interface PolygonRepository extends JpaRepository<Polygon, Long> {
    // 其他自定义查询方法...
}

@Service
public class PolygonService {
    private final PolygonRepository polygonRepository;

    public PolygonService(PolygonRepository polygonRepository) {
        this.polygonRepository = polygonRepository;
    }

    public void savePolygon(List<Point> coordinates) {
        Polygon polygon = new Polygon();
        polygon.setCoordinates(coordinates);
        polygonRepository.save(polygon);
    }

    // 其他业务逻辑方法...
}
