hibernate用注解(annotation)配置sequence

@Id
 
@SequenceGenerator(name="sequenceGenerator",sequenceName="ACTIVITIESSCOPE_SEQ")
 
@GeneratedValue(generator="sequenceGenerator",strategy=GenerationType.SEQUENCE)
 
@Column(name = "ID", unique = true, nullable = false, precision = 10, scale = 0)
 
public Long getId() {
 
 return this.id;
 
}

注意：
@GeneratedValue中的generator不是sequence的名字，而是@SequenceGenerator中的name的名字；
@SequenceGenerator中的sequenceName才是定义sequence的名字。
