Boa Tarde,

Quando tento persistir os dados no banco MYSQL, aparece a seguinte mensagem de erro.

Tem erro de sintaxe na sua Query, posta ela ai.

Este erro está associado à forma como você mapeou a(s) entidade(s).
Se quiser, posta aí, tanto a entity quanto a configuração do hibernate.

----- Entidade -----

package pacotehibernate;

import javax.persistence.Entity;

import <a href="http://javax.persistence.Id">javax.persistence.Id</a>;

Para o MySQL, eu sempre mapeei da seguinte maneira:

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;

Aí temos o seguinte, se você está criando as tabelas pelo próprio hibernate, ele criará da seguinte maneira

CREATE TABLE foo (
    id BIGINT NOT NULL PRIMARY KEY AUTO_INCREMENT,
    ...
);

Ou algo bem parecido.
Caso contrário, teu banco precisa ter as tabelas criadas mais ou menos da mesma maneira.

No teu mapeamento, como você não especifica a estratégia para o generation type, creio que o hibernate tente, por padrão, utilizar SEQUENCE, que é uma abordagem não usual para o MySQL.

Fiz o mapeamento conforme dito, mas apareceu o seguinte erro:

Só colocar o log, sem as alterações que fez, fica difícil.
Você está fazendo essa configuração seguindo qual tutorial/livro/apostila?

Estou seguindo uma apostila antiga da K19. Tem algum material mais atual que possa me indicar?
Fiz umas modificações no cfg e no persistence. Segue:

	return Nome;
}
/**

/**

public Long getId() {

Acredito que a K19 tenha material atualizado.
Além disso, creio que a Caelum ainda disponibilize apostilas com esse conteúdo.
Se não, se procurar, encontra até vídeos no youtube com isso.
