Hibernate is not mapping classes

Hibernate I'm using is not automatically generating tables

My Persistence.xml file

My Class with annotations

package br.com.model;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Table;
import javax.persistence.Id;

@Entity
@Table(name="departamento")
public class Departamento {

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    @Column(name="id")
    private int Id;

    @Column(name="nome")
    private String Nome;

    public int getId() {
        return Id;
    }

    public void setId(int id) {
        Id = id;
    }

    public String getNome() {
        return Nome;
    }

    public void setNome(String nome) {
        Nome = nome;
    }



}
