H2 database: NULL not allowed for column “ID” when inserting record using jdbcTemplate

Question

I use hibernate\'s hbm2ddl to generate schema automatically. Here is my domain:

@Entity
public class Reader {

  @Id
  @GeneratedValue(strategy=GenerationTyp         


        

Answer 1

Try to use strategy=GenerationType.IDENTITY instead of the strategy=GenerationType.AUTO

Also could be wrong hibernate.dialect Try the

hibernate.dialect=org.hibernate.dialect.H2Dialect
