下面是一个用Hibernate实现对数据库进行批量操作的示例

public class AddMoreWords {

private static String type = "idiom";
/**
* @param args
*/
public static void main(String[] args) throws Exception {
  // TODO Auto-generated method stub

  Session session = HibernateSessionFactory.currentSession();
  Transaction txc = session.beginTransaction();
  for(int i=0;i<1000;++i){
   WordLib word = new WordLib();
   word.setChn("mm"+(i+1));
   word.setTime(new Date());
   word.setType(type);
   session.save(word);
   if((i+1)%25 == 0){
    session.flush();
    session.clear();
   }
  }
//  WordLib word = new WordLib();
//  word.setChn("a");
//  word.setTime(new Date());
//  word.setType(type);
//  session.save(word);
  txc.commit();
  HibernateSessionFactory.closeSession();
  session.flush();
  session.close();
}

}
