java - org.hibernate.MappingException : Could not determine type

Question

我有一个应用程序(使用注释的 Spring 4 MVC+Hibernate 4+MySQL+Maven 集成示例)，使用基于注释的配置将 Spring 与 Hibernate 集成，我看到启动应用程序时会自动创建架构。但我没有这个属性

我有这张表:

CREATE TABLE `t_device_event` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `device_event_lat` float(10,6) DEFAULT NULL,
  `device_event_lng` float(10,6) unsigned NOT NULL,
  `device_id` int(11) unsigned NOT NULL,
  `device_event_message` varchar(100) DEFAULT NULL,
  `device_event_received` TIMESTAMP ,
  `device_event_coordinates` point DEFAULT  NULL,
  PRIMARY KEY (`id`),
  KEY `device_id` (`device_id`),
  CONSTRAINT `t_device_event_ibfk_1` FOREIGN KEY (`device_id`) REFERENCES `t_device` (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

还有这个 bean

@Entity
@Table(name="t_device_event")
public class DeviceEvent {

    public class Coordinates {

        private Double lat;

        private Double lng;


        public Coordinates(Double lat, Double lng) {
            super();
            this.lat = lat;
            this.lng = lng;
        }

        public Double getLat() {
            return lat;
        }

        public void setLat(Double lat) {
            this.lat = lat;
        }

        public Double getLng() {
            return lng;
        }

        public void setLng(Double lng) {
            this.lng = lng;
        }

    }

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;

    @ManyToOne
    @JoinColumn(name="device_id")
    private Device device;


    @Column(name = "device_event_received")
    private Long received;


    @Column(name = "device_event_message")
    private String message;



    @Column(name = "device_event_coordinates")
    private Coordinates coordinates;


    public Coordinates getCoordinates() {
        return coordinates;
    }

    public void setCoordinates(Coordinates coordinates) {
        this.coordinates = coordinates;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public Device getDevice() {
        return device;
    }

    public void setDevice(Device device) {
        this.device = device;
    }

    public Long getReceived() {
        return received;
    }

    public void setReceived(Long received) {
        this.received = received;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public DeviceEvent(Device device) {
        super();
        this.device = device;
    }
}

但是我在启动应用程序时遇到此错误:

Answer 1

device_event_coordinates 列与其在 query 和 DeviceEvent 类中的类型不匹配。

    @Column(name = "device_event_coordinates")
     private Coordinates coordinates;

还有:

  `device_event_coordinates` `point` DEFAULT  NULL,
