Erro ao inserir dados no hibernate

Programação Java
#1

Ola rapaziada!
Tenho um banco legado aqui. E algumas tabelas não tem auto incremento na pk. To usando o hibernate com annotations. Alguém tem idéia do que tenho que fazer para que o hibernate aceite receber os objetos.
O hibernate me joga esta exception:

Caused by: java.sql.SQLException: Field ‘idAluno’ doesn’t have a default value

Provavelmente o ID não tem autoincremented, como você está setando ID na hora de criar o bean ?

[/color]

    @Entity
    public class Alunos{
    @Id
    @GeneratedValue
    private Long id;

     public Long getId() {
 		return id;
     }
 
 	public void setId(Long id) {
 		this.id = id;
 	}
     }

Então metaleiro. Ta igualzinho ao código que vc postou e mesmo assim gera este erro.
:sad:

Qual banco de dados tu ta usando… e qual a SQL q o hibernate gera desse insert?
