如何通過獲取列進行排序？

我斷言：

CriteriaQuery<Connection> cquery = (CriteriaQuery<Connection>) query; 
Fetch<Connection, ConnectionResearch> researches = root.fetch(Connection_.researches, JoinType.INNER); 
cquery.orderBy(cb.asc(/* researches.get(ConnectionResearch_.pullforce) */)); 

如何通過ConnectionResearch.pullforce設置選擇查詢順序讀取列？

解決方案：

Join<Connection, ConnectionResearch> researches = (Join<Connection, ConnectionResearch>) root.fetch(Connection_.researches); 
cquery.orderBy(cb.asc(researches.get(ConnectionResearch_.pullForce)));
