map排序

map  = list.stream().collect(
                    Collectors.groupingBy(ClueRule::getCrScore ,Collectors.toList()))
                    .entrySet().stream()
                    .sorted(Map.Entry.comparingByKey())
                    .collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue,
                            (oldValue, newValue) -> oldValue, LinkedHashMap::new));
