I have this error in my eclipse editor This class has a composite primary key. It must use an ID class. , but the class does not has a composite primary key, because the id is a Long
@SuppressWarnings("serial")
@Entity
@Table(name = "T_PRODUCT")
@SequenceGenerator(name = "seqPRODUCT", sequenceName = "SEQ_PRODUCT")
public class Product extends ItemBase implements java.io.Serializable {
@Id
private Long id;
@Id
@Column(name = "ID", unique = true, nullable = false, precision = 38, scale = 0)
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "seqPRODUCT")
public Long getId() {
return this.id;
}
public void setId(Long id) {
this.id = id;
}
..
}

Hibernate is seeing both annotations on the property and on the getter-method and therefore assumes that you are using a composite key.
