Minha classe produto está assm:

@Entity
public class Produto {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;
    private String titulo;
    private String desc;
    private int paginas;
    // sem necessidade de gerenciar produto pelo id
    @ElementCollection
    private List<Preco> precos;

    public String getTitulo() {
        return titulo;
    }

    public void setTitulo(String titulo) {
        this.titulo = titulo;
    }

    public int getPaginas() {
        return paginas;
    }

    public void setPaginas(int paginas) {
        this.paginas = paginas;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }


    public String getDesc() {
        return desc;
    }

    public void setDesc(String desc) {
        this.desc = desc;
    }

    public List<Preco> getPrecos() {
        return precos;
    }

    public void setPrecos(List<Preco> precos) {
        this.precos = precos;
    }

    @Override
    public String toString() {
        return "Produto [id=" + id + ", titulo=" + titulo + ", desc=" + desc + ", paginas=" + paginas + ", precos="
                + precos + "]";
    }



}

e a classe preço esta assim:

@Embeddable
public class Preco {

    private BigDecimal valor;
    private TipoPreco tipo;

    public BigDecimal getValor() {
        return valor;
    }

    public void setValor(BigDecimal valor) {
        this.valor = valor;
    }

    public TipoPreco getTipo() {
        return tipo;
    }

    public void setTipo(TipoPreco tipo) {
        this.tipo = tipo;
    }

    @Override
    public String toString() {
        return "Preco [valor=" + valor + ", tipo=" + tipo + "]";
    }



}

Alguém sabe o porque deste erro?

EDIT: Dei drop em todas as tabelas e estou tentando rodar novamente o projeto mas agora a tabela Produto não é nem mais criada pelo hibernate

E aí Thales, tudo bem ?

Cara, pela exception ta dando erro de sintaxe no sql gerado. Coloca aqui pra gente como estão suas classes de configuração da JPA, e também seu Dao, pra gente poder dar uma olhada.

solução!

Opa, beleza?

Consegui achar onde estava o problema, no meu model de Produto a descrição estava como desc e por isso não era possível criar a tabela ou fazer insert nela. Acredito que desc seja nome de alguma entidade interna do mysql.

Para resolver o problema renomeei para descricao e agora esta funcionando normalmente.
