hibernate save (Batch update returned unexpected row count from update [0];)

yeqing219 2011-08-30 12:55:17
这个是保存代码
	public boolean save(UomConversion transientInstance) {

		boolean status=false;

		log.debug("saving UomConversion instance");

		try {

			Session session=getSession();

			Transaction tc=session.beginTransaction();

			session.save(transientInstance);

			tc.commit();

			status=true;

			log.debug("save successful");

		} catch (RuntimeException re) {

			log.error("save failed", re);

			throw re;

		}

		return status;

	}

这个是配置
