ProjectionList projList = Projections.projectionList();
projList.add(Projections.property("request.requestId"));
projList.add(Projections.property("request.createdDate"));
projList.add(Projections.property("request.tripType"));
projList.add(Projections.property("request.origin"));
projList.add(Projections.property("request.destination"));
projList.add(Projections.property("request.noOfAdult"));
projList.add(Projections.property("request.noOfChild"));
projList.add(Projections.property("request.noOfInfant"));
projList.add(Projections.property("request.requestStatus"));
projList.add(Projections.property("request.paymentStatus"));
projList.add(Projections.property("request.totalFare"));
projList.add(Projections.property("request.lastUpdatedDate"));
projList.add(Projections.property("request.total"));
criteria.setProjection(Projections.distinct(projList));
criteria.addOrder(Order.desc("request.totalCount"));
现在我想根据request.noOfAdult，request.noOfChild，request.noOfInfant的总和对这些记录进行排序。
如果我需要对任何一个字段进行排序，那么我可以执行criteria.addOrder（Order.asc（“request.noOfAdult”）），但我需要对这三个字段的总和进行...
我如何才能实现此功能？
