If the Order_Sequence
column is the IDENTITY, then the Primary Key column must be manually assigned.
If that’s the case, then the ID column must be mapped like this:
@Id
@Column(name = "ID")
private Long id;
while the Order_Sequence
column will be mapped as follows:
@Generated( value = GenerationTime.INSERT)
@Column(name = "Order_Sequence")
private Long orderSequence;
Try it like this and let me know how it works.
