[PersistenceException: Error getting sequence nextval]

Question

i am getting this error while trying to save data into model in db.

@Entity
public class User extends Model {
   @Required
   public String name; 
   @Email         


        

Answer 1

This worked for me:

@Entity
@Table(name = "table", schema = "schema")
public class Bean extends Model{

   @Id
   @Column(name = "idcolumn")
   @SequenceGenerator(name="gen", sequenceName="schema.table_idcolumn_seq",allocationSize=1) 
   @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "gen")
   private int id;
}

When using the SequenceGenerator, please mind this bug in Hibernate: https://hibernate.atlassian.net/browse/HHH-7232

It forces you to write the schema directly into the sequenceName instead of using the schema field in the SequenceGenerator annotation.
