Could not determine type for: java.util.Collection, at table:
该错误有可能的原因是: 在实体类的属性中的annotation, 要么就全写在属性上,要么就全写在get方法上,不能混用。
@Entity
@SequenceGenerator(name = "Person_Seq", sequenceName = "person_seq")
public class Person implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "Person_Seq")
private int id;
@Column(name = "name")
private String name;
// @ManyToOne
// @JoinColumn(name="unitid")
@ManyToOne
@JoinColumn(name = "unitid")
private Unit unit;
private static final long serialVersionUID = 1L;
public Person() {
super();
}
public int getId() {
return this.id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return this.name;
}
public void setName(String name) {
this.name = name;
}
public Unit getUnit() {
return unit;
}
public void setUnit(Unit unit) {
this.unit = unit;
}
}
把@ManyToOne移到getUnit上就会出错
