如何按获取列排序？

我的谓词:

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

如何通过ConnectionResearch.pullforce获取列设置选择查询顺序？

解决方案:

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