Ok the problem is that for executeFind() the return type is List....so there is no way to use uniqueResult() within the callback from executeFind()...may be we should use execute()

上面這段話來自http://forum.springframework.org/showthread.php?t=58370

?

在使用executeFind方法時(shí)，如果返回的不是List類型的數(shù)據(jù)則會(huì)出現(xiàn)引異常

例:
?public Integer findCount(final Class clazz,final String str) {
??return Integer.parseInt(getHibernateTemplate().executeFind(new HibernateCallback()
??{

???@Override
???public Object doInHibernate(Session session)
?????throws HibernateException, SQLException {
????StringBuilder sb=new StringBuilder();
????sb.append("select count(*) from ");
????sb.append(clazz.getName());
????sb.append(" ");
????sb.append(str);
????log.info(sb.toString());
????return session.createQuery(sb.toString()).uniqueResult();
???}
???
??}).toString());
?}

解決方法是把executeFind方法改為execute方法

?public Integer findCount(final Class clazz,final String str) {
??return Integer.parseInt(getHibernateTemplate().execute(new HibernateCallback()
??{

???@Override
???public Object doInHibernate(Session session)
?????throws HibernateException, SQLException {
????StringBuilder sb=new StringBuilder();
????sb.append("select count(*) from ");
????sb.append(clazz.getName());
????sb.append(" ");
????sb.append(str);
????log.info(sb.toString());
????return session.createQuery(sb.toString()).uniqueResult();
???}
???
??}).toString());
?}
