Auto Increment Oracle Table Id Mapping With JPA Entity

When you create entities file of the mysql table with JPA, auto increment field 'id' is mapped as follows.     @Id        @GeneratedValue(strategy = GenerationType.IDENTITY)     @Basic(optional = false)     @NotNull     @Column(name = "id")     private Long id; However, Oracle doesn't support auto increment. Hence sequence generator is set up for the field id of table. The respective entity mapping for 'id' should be changed as below.     @Id        @GeneratedValue(strategy = GenerationType.IDENTITY)     @Basic(optional = false)     @NotNull     @Column(name = "id")     private Long id;     @SequenceGenerator(initialValue=1, sequenceName="INVOICE_SEQ",allocationSize=1,name="invoice_seq_name")     @GeneratedValue(generator="invoice_seq_name")
