私は、hibernate JPA 2 + springを使用してWebアプリケーションを構築します。私はドメインモデルの作成に問題があります。永続性では、エンティティからデータベーステーブルの自動作成を宣言しました。ここに私のpersistence.xmlファイルがあります：永続性はデータベース内のエンティティからテーブルを作成しません
<persistence-unit name="basicPersistenceUnit" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect"/>
<property name="hibernate.hbm2ddl.auto" value="create"/>
<property name="hibernate.connection.charSet" value="UTF-8"/>
</properties>
</persistence-unit>
私は2つのクラスを持っています。一つは継承されたクラスに永続性を提供する抽象的です：ここで
import org.hibernate.annotations.GenericGenerator;
import org.hibernate.type.UUIDBinaryType;
import javax.persistence.*;
@MappedSuperclass
abstract class AbstractDomainObject implements DomainObject {
private static final long serialVersionUID = 1L;
private UUIDBinaryType id;
private Long version;
@Id
@GeneratedValue(generator = "system-uuid")
@GenericGenerator(name = "system-uuid", strategy = "uuid")
@Column(length = 16, unique = true, nullable = false)
public final UUIDBinaryType getId() {
return id;
}
public final void setId(UUIDBinaryType id) {
this.id = id;
}
@Version
public final Long getVersion() {
return version;
}
public final void setVersion(Long version) {
this.version = version;
}
@Override
public boolean equals(Object o) {
if (this == o) return true;
if (!(o instanceof AbstractDomainObject)) return false;
AbstractDomainObject that = (AbstractDomainObject) o;
return !(id != null ? !id.equals(that.id) : that.id != null) &&
!(version != null ? !version.equals(that.version) : that.version != null);
}
@Override
public int hashCode() {
int result = id != null ? id.hashCode() : 0;
result = 31 * result + (version != null ? version.hashCode() : 0);
return result;
}
}
は、エンティティを表す具体的なクラスである：ここでは
import javax.persistence.Entity;
@Entity
public class Person extends AbstractDomainObject {
private static final long serialVersionUID = 1L;
private String name;
private String surname;
private Integer identifier;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSurname() {
return surname;
}
public void setSurname(String surname) {
this.surname = surname;
}
public Integer getIdentifier() {
return identifier;
}
public void setIdentifier(Integer identifier) {
this.identifier = identifier;
}
@Override
public boolean equals(Object o) {
if (this == o) return true;
if (!(o instanceof Person)) return false;
if (!super.equals(o)) return false;
Person test = (Person) o;
return !(name != null ? !name.equals(test.name) : test.name != null) &&
!(surname != null ? !surname.equals(test.surname) : test.surname != null) &&
!(identifier != null ? !identifier.equals(test.identifier) : test.identifier != null);
}
@Override
public int hashCode() {
int result = super.hashCode();
result = 31 * result + (name != null ? name.hashCode() : 0);
result = 31 * result + (surname != null ? surname.hashCode() : 0);
result = 31 * result + (identifier != null ? identifier.hashCode() : 0);
return result;
}
}
は、私は抽象クラスで使用しているインタフェースです。
import org.hibernate.type.UUIDBinaryType;
import java.io.Serializable;
public interface DomainObject extends Serializable {
UUIDBinaryType getId();
void setId(UUIDBinaryType id);
Long getVersion();
void setVersion(Long version);
boolean equals(Object o);
int hashCode();
}
そしてここでは、デバッグモードでのTomcatからのログです：

このログにはエラーはなく、スキーマのエクスポートに関する情報は完全ですが、テーブルPersonはデータベースに作成されていません。私は間違った方法で何かをしますか？
