Hibernate + SQLite没有创建数据库
这是我的问题：
我有一个使用JavaFX + Hibernate + SQLite的桌面应用程序。 这是我的模特：
@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) { this.id = id; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPasword(String password) { this.password = password; } public Boolean getAdministrador() { return administrador; } public void setAdministrador(Boolean administrador) { this.administrador = administrador; } public Integer getVersion() { return version; } 这是我的persistence.xml
org.hibernate.ejb.HibernatePersistence br.com.gear7.partyrock.model.Usuario
最后这是我的SQLiteDialect

当我运行我的应用程序时，一切顺利但数据库文件没有被创建，这意味着我的表也没有被创建。
在过去的3个小时里一直在努力，但找不到任何解决方案。
对不起，我花了这么长时间，但这就解决了我的问题。 我将DIALECT文件更改为我找到的更好的文件。

我在persistence.xml上更改了这一行
这解决了我。 🙂
当你运行你的代码时你可以存储数据库吗？
查看你的persistence.xml我可以看到
只需在persistence.xml中添加此
