Hibernate + SQLite non la creazione di database

Question

Ecco il mio problema:

Ho un'applicazione desktop utilizzando JavaFX + Hibernate + SQLite. Questo è il mio modello:

@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; 
    } 

Questo è il mio 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"> 
    <persistence-unit name="PartyRockPU" transaction-type="RESOURCE_LOCAL"> 
    <provider>org.hibernate.ejb.HibernatePersistence</provider> 
    <class>br.com.gear7.partyrock.model.Usuario</class> 

    <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> 

E infine questo è il mio SQLiteDialect

Quando eseguo la mia applicazione, tutto va liscio, ma il il file di database non viene creato, il che significa che anche la mia tabella non viene creata.

lottando con questo per gli ultimi 3 ore e non può trovare alcuna soluzione per esso.

Answer 1

mi dispiace che mi ha portato così a lungo, ma qui è quello che ha risolto il problema per me. Ho cambiato il file DIALECT in uno migliore che ho trovato.

E ho cambiato questa linea sul mio persistence.xml

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

Ciò ha risolto per me. :)

Answer 2

Quando si esegue il codice si può memorizzare le cose il database?

Guardando il tuo persistence.xml posso vedere <property name="hibernate.hbm2ddl.auto" value="create-drop"/> che creerà un DB all'avvio di Hibernates, quindi cancellarlo quando Hibernate si spegne. Potrebbe facilmente accadere che il DB venga creato ma Hibernate che lo elimina sia rimuovendolo.

Answer 3

Basta aggiungere questo nome < property = "hbm2ddl.auto"> Crea </property> in persistence.xml. Funzionerà. Ma l'altro, oltre alla creazione, non funziona.
