Hibernate + SQLite không tạo cơ sở dữ liệu

Question

Đây là vấn đề của tôi:

Tôi có ứng dụng dành cho máy tính để bàn bằng JavaFX + Hibernate + SQLite. Đây là mẫu của tôi:

@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; 
    } 

Đây là persistence.xml tôi

<?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> 

Và cuối cùng này là SQLiteDialect tôi

Khi tôi chạy ứng dụng của tôi, tất cả mọi thứ diễn ra trôi chảy nhưng tệp cơ sở dữ liệu không được tạo, nghĩa là bảng của tôi cũng không được tạo.

Đã đấu tranh với vấn đề này trong 3 giờ qua và không thể tìm thấy giải pháp nào cho nó.

Answer 1

Tôi xin lỗi đã mất quá nhiều thời gian, nhưng đây là những gì đã giải quyết được vấn đề cho tôi. Tôi đã thay đổi tệp DIALECT thành tệp tốt hơn mà tôi đã tìm thấy.

Và tôi đã thay đổi dòng này trên persistence.xml tôi

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

này giải quyết cho tôi. :)

Answer 2

Khi bạn chạy mã, bạn có thể lưu trữ những thứ cơ sở dữ liệu không?

Nhìn vào persistence.xml của bạn, tôi có thể thấy <property name="hibernate.hbm2ddl.auto" value="create-drop"/> sẽ tạo một DB khi khởi động ngủ đông sau đó xóa nó khi ngủ đông tắt. Nó có thể dễ dàng được rằng DB đang được tạo ra nhưng Hibernate thả DB là loại bỏ nó.

Answer 3

Chỉ cần thêm tên < tài sản = "hbm2ddl.auto" này> tạo </property> trong persistence.xml. Nó sẽ hoạt động. Nhưng khác hơn là tạo ra không hoạt động.
