Session session = sessionFactory.openSession();
 Transaction tx = session.beginTransaction();

String sqlInsert = "insert into sampletbl (name) values (?) ";
for(String name : list){
   session.createsqlQuery( sqlInsert )
          .setParameter(1,name)
          .executeUpdate();
} 
tx.commit();
session.close();

Hibernate有一个批处理功能.但在上面的例子中,我使用的是Native sql,根据我的观察,hibernate批处理对于Native sql来说效果不是很好.是的,它确实避免了内存不足错误,但没有提高性能.
因此我退回到在Hibernate中实现了JDBC Batch.Hibernate提供了方法doWork()来从Hibernate Session获取Connection.

Session session = sessionFactory.openSession();
Transaction tx = session.beginTransaction();
//get Connction from Session
session.doWork(new Work() {
       @Override
       public void execute(Connection conn) throws sqlException {
          PreparedStatement pstmt = null;
          try{
           String sqlInsert = "insert into sampletbl (name) values (?) ";
           pstmt = conn.prepareStatement(sqlInsert );
           int i=0;
           for(String name : list){
               pstmt .setString(1,name);
               pstmt .addBatch();

               //20 : JDBC batch size
             if ( i % 20 == 0 ) { 
                pstmt .executeBatch();
              }
              i++;
           }
           pstmt .executeBatch();
         }
         finally{
           pstmt .close();
         }                                
     }
});
tx.commit();
session.close();
