java Postgres点类型列到Spring实体数据类型

Question

我有一张postgres表：

CREATE TABLE public.geometry
(
    id          serial not null primary key,
    coordinates point not null

);

我正在尝试从使用Spring的服务器中检索一行作为JSON响应API，其类如下：

@Entity
@Table(name = "geometry",schema = "public")
@JsonIdentityInfo(generator=RefIntSequenceGenerator.class)
public class Cylinder
{

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id", columnDefinition = "serial", updatable = false, nullable = false)
    @NotNull
    private long id;

    @NotNull
    private Point coordinates;

    public long getId()
    {
        return id;
    }

    public Point getCoordinates() {
        return coordinates;
    }
}

但当我试图接近终点时，我得到：

could not deserialize; nested exception is org.hibernate.type.SerializationException: could not deserialize
