最近发现HIBERNATE可以动态更换表名，真不简单，下面把原代码贴出来供参考：
public class ReportDBApi {
private SessionFactory sessionFactory = null;
public ReportDBApi(){
createSession();
}
public void createSession(){
Date date = new Date();
SimpleDateFormat simpledateformat = new SimpleDateFormat("yyyyMMdd");
String now_time = simpledateformat.format(date);
String tablename = "TBL_REPORT_STATUS_20050707";
tablename = "TBL_REPORT_STATUS_" + now_time;
try {
Configuration cfg = new Configuration().addClass(cn.sports.vas.sms.unicom.TblReportStatus.class).configure();
Table table = cfg.getClassMapping(TblReportStatus.class).getTable();
table.setName(tablename);
cfg.getClassMapping(TblReportStatus.class).setTable(table);
sessionFactory = cfg.buildSessionFactory();
}
catch (MappingException ex) {
ex.printStackTrace();
}catch (HibernateException ex) {
ex.printStackTrace();
}
}
public void insertPO(TblReportStatus po) throws HibernateException {
Session session = sessionFactory.openSession();
Transaction tx = session.beginTransaction();
session.save(po);
tx.commit();
session.close();
}
public void closeSession() throws HibernateException {
sessionFactory.close();
}
}
这个类是每天新建一张表，并往里写数据。
