Hibernate + SQLite沒有創建數據庫

我有一個使用JavaFX + Hibernate + SQLite的桌面應用程序。這是我的模型：

@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; 
    }

這是我的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>

最後，這是我SQLiteDialect

當我運行我的應用程序，一切順利，但數據庫文件不會被創建，這意味着我的表也不會被創建。

過去3個小時一直在爲此付出努力，無法找到任何解決方案。

我也有同樣的問題，你找到一個解決方案？ – Ha11owed

您使用哪個平臺編寫代碼和版本？ –

最後你解決了你的問題？如果是，你可以分享解決方案嗎？謝謝。 –

對不起，我花了這麼長時間，但這是什麼解決了我的問題。我將DIALECT文件更改爲我找到的更好的文件。

，我改變了這一行對我的persistence.xml

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

這解決了我。 :)

當你運行你的代碼時你可以存儲數據庫的東西嗎？

看着你的persistence.xml，我可以看到<property name="hibernate.hbm2ddl.auto" value="create-drop"/>這將在休眠啓動時創建一個數據庫，然後在休眠關閉時將其刪除。可能很容易，數據庫正在創建，但Hibernate刪除數據庫正在刪除它。

我已經嘗試過創建更新，更新，驗證，創建和其他可能的值..沒有工作 – renatojf

只需在persistence.xml中添加此 < property name =「hbm2ddl.auto」>創建</property> 。它會工作。但其他 - 比創建不工作。
