Hibernate + SQLite не создает базу данных

Question

Вот моя проблема:

У меня есть приложение на рабочем столе с помощью JavaFX + Hibernate + SQLite. Это моя модель:

@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; 
    } 

Это мой persistence.xml

<?xml version="1.0" encoding="UTF-8"?> 
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">

    <properties> 
     <property name="javax.persistence.jdbc.driver" value="org.sqlite.JDBC" /> 
     <property name="javax.persistence.jdbc.url" value="jdbc:sqlite:party_rock.sqlite" /> 
     <property name="javax.persistence.jdbc.user" value="" /> 
     <property name="javax.persistence.jdbc.password" value="" /> 

     <property name="hibernate.dialect" value="br.com.gear7.partyrock.utils.SQLiteDialect"/> 
     <property name="hibernate.ejb.naming_strategy" value="org.hibernate.cfg.ImprovedNamingStrategy"/> 
     <property name="hibernate.connection.charSet" value="UTF-8"/> 
     <property name="hibernate.hbm2ddl.auto" value="create-drop"/> 
    </properties> 
    </persistence-unit> 
</persistence> 

И, наконец, это мой SQLiteDialect

Когда я запускаю мое приложение, все идет гладко, но файл базы данных не создается, что означает, что моя таблица также не создается.

Был на связи с этим в течение последних 3 часов и не может найти решения для этого.

Answer 1

Мне жаль, что меня так долго не хватало, но вот что решило проблему для меня. Я изменил файл DIALECT на лучший, который нашел.

И я изменил эту линию на моем persistence.xml

<property name="hibernate.hbm2ddl.auto" value="update"/> 

Это решало для меня. :)

Answer 2

Когда вы запускаете свой код, вы можете хранить вещи в базе данных?

Глядя на ваш persistence.xml Я могу видеть <property name="hibernate.hbm2ddl.auto" value="create-drop"/>, который создаст БД при запуске спящего режима, а затем удалит его, когда спящий режим выключится. Легко было бы, что БД создается, но Hibernate, удаляющий БД, удаляет его.

Answer 3

Просто добавьте имени < свойства = "hbm2ddl.auto"> создать </недвижимости> в persistence.xml. Это будет работать. Но другое, чем создание, не работает.
