java用hibernate向anywhere9中插入一百万条记录

表名：test，只有一个列id varchar(50)；

hibernate.cfg.xml内容：

<?xml version='1.0' encoding='UTF-8'?>

java程序：

import java.text.SimpleDateFormat;

import org.hibernate.Session;
import org.hibernate.Transaction;

public class hibernateConnectAnywhere {

    tableTest.setId("This is message" + i);
    session.save(tableTest);
    if ( i % 50 == 0 ) {//50行提交一次
              session.flush();
              session.clear();//清一级缓存，防止内存溢出
