ここに私の問題があります：Hibernate + SQLiteデータベースが作成されていません
私はJavaFX + Hibernate + SQLiteを使用するデスクトップアプリケーションを持っています。 これは私のモデルである：これは私のpersistence.xml

@Entity
@Table(name = "usuario")
public class Usuario implements AbstractModel, Serializable {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;
@NotNull @Size(min=5, max=100)
private String username;
@NotNull @Size(min=5, max=100)
private String password;
@NotNull
private Boolean administrador;
@Version
private Integer version;
public Usuario() {
}
public Usuario(Integer id, String username, String password, Boolean admin, Integer version) {
this.id = id;
this.username = username;
this.password = password;
this.administrador = admin;
this.version = version;
}
@Override
public Integer getId() {
return id;

public void setId(Integer id) {

そして最後に、これは私のSQLiteDialect

私は自分のアプリケーションを実行している、すべてが順調にはなくなりますデータベースファイルは作成されません。つまり、私のテーブルも作成されません。
これは過去3時間でこれと苦労しており、解決策が見つかりませんでした。
私も同じ問題を抱えていますが、解決策を見つけましたか？ – Ha11owed
あなたはコードとバージョンの書き込みにどのプラットフォームを使用しましたか？ –
最後に問題を解決しましたか？はいの場合は、ソリューションを共有できますか？ありがとう。 –
