我有一個應用程序（使用註釋的Spring 4 MVC + Hibernate 4 + MySQL + Maven集成示例），使用基於註釋的配置集成了Spring和Hibernate，我發現該模式是自動的當我啓動應用程序時創建。但我沒有這個屬性org.hibernate.MappingException：無法確定類型
我有這個表：
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;
和這個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;
}
}
，但我有這個錯誤在啓動應用程序：
