HQL帮忙排错，谢谢前辈
String hql ="update Cmis_quality_cul_news set state=:state and audittimes=：audittimes where id=:id";

[解决办法]
String hql ="update Cmis_quality_cul_news set state=:state and audittimes=：audittimes where id=:id";

String hql ="update Cmis_quality_cul_news set state=:state, audittimes=:audittimes where id=:id";

set字段值，多个用逗号（半角）分隔，不是and。
注意冒号也是半角的。
