JPA：在非id列上使用@GeneratedValue

@GeneratedValue(generator = "RFQ_LINE_IDS_SEQUENCE",strategy=GenerationType.SEQUENCE)
@SequenceGenerator(name="RFQ_LINE_IDS_SEQUENCE",sequenceName="RFQ_LINE_IDS_SEQUENCE",allocationSize=1000000000)
@Column(name = "external_line_item_id")
private String externalLineItemId;

我在网上看到的所有例子都显示这个注释与@Id一起使用,但我有另一个属性,我正在使用我的id.

我也试过以下无济于事：

@GeneratedValue(generator = "RFQ_LINE_IDS_SEQUENCE",strategy=GenerationType.SEQUENCE)
@GenericGenerator(name = "RFQ_LINE_IDS_SEQUENCE",strategy = "sequence",parameters = {@Parameter(name = "sequence",value = "RFQ_LINE_IDS_SEQUENCE")})
@Column(name = "external_line_item_id")
private String externalLineItemId;
