MyEclipse にエンティティ クラスがあります。
import javax.persistence.Entity;
import javax.persistence.Id;
@Entity
public class User{
@Id
private int userId;
private String userName;
public User(int userId, String userName){
this.userId = userId;
this.userName = userName;
}
私は自分の設定xmlを持っています:
<?xml version='1.0' encoding='UTF-8'?>
<!-- Generated by MyEclipse Hibernate Tools. -->
<hibernate-configuration>
<session-factory>
<property name="dialect">
org.hibernate.dialect.SQLServerDialect
</property>
<property name="connection.url">
jdbc:sqlserver://localhost:1433;databaseName=SecondHibernate
</property>
<property name="connection.username">maomaoda1988</property>
<property name="connection.password">maomaoda1988</property>
<property name="connection.driver_class">
com.microsoft.sqlserver.jdbc.SQLServerDriver
</property>
<property name="myeclipse.connection.profile">
SecondHibernate
</property>
<property name="show_sql">true</property>
<property name="connection.pool_size">1</property>
<property name="hibernate.hbm2ddl.auto">create</property>
<mapping class="entity.User" />
</session-factory>
</hibernate-configuration>
そして私は主な方法を持っています
package hibernateTest;
import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.Transaction;
import entity.*;
import hibernate.*;
public class HibernateTest {
public static void main(String[] args) {
Session session = HibernateSessionFactory.getSession();
User user = new User(1, "Chris");
Transaction t = null;
try{
t = session.beginTransaction();
session.save(user);
t.commit();
}
catch (HibernateException e){
if(t != null) t.rollback();
e.printStackTrace();
}
finally{
session.close();
}
}
}
ただし、エラーが発生しました：

データベースにテーブルがありません。Hibernate でエンティティ クラスに基づいてテーブルを自動的に作成したいと考えています。どうすればこれを達成できますか? どうもありがとうございました。
