@SequenceGenerator(name = "SEQ_HRMS_EMP", sequenceName = "SEQ_HRMS_EMP", initialValue = 1, allocationSize = 1)
@GeneratedValue(strategy = GenerationType.AUTO, generator = "SEQ_HRMS_EMP")

   user_id integer not null auto_increment,
   
   MySql will ignore the generator = "SEQ_HRMS_EMP" setting because MySql does not have sequence.

3. Oracle
