hibernate中SchemaExport方式创建表

[test]

package test;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.AnnotationConfiguration;
import org.hibernate.tool.hbm2ddl.SchemaExport;
import org.junit.Test;

public class testUsers {

 @Test
 public void testSchemaExport() {
  SessionFactory sessionFactory = new AnnotationConfiguration()
    .configure().buildSessionFactory();
  SchemaExport export = new SchemaExport(
    new AnnotationConfiguration().configure());
  export.create(true, false);
  Session session = sessionFactory.getCurrentSession();
  session.beginTransaction();
  session.getTransaction().commit();

 }

}

 

[hibernate.cfg.xml] 这里注意去掉hbm2ddl.auto

  this.id = id;
 }
 public void setLevel(String level) {
  this.level = level;
 }
 public void setTitle(String title) {
  this.title = title;
 }
 
}
