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。
