java8 Stream排序字段為空排序方法

minPriceList.stream().sorted(Comparator.comparing(l -> l.getCreateDate(), Comparator.nullsLast(Date::compareTo))).findFirst().get();

List<EnterpriseRankVo> result = enterpriseRankVoList.stream().sorted((Comparator.comparing(EnterpriseRankVo::getRank).reversed())).skip(pageable.getSize() * (pageable.getCurrent() - 1))
        .limit(pageable.getSize()).collect(Collectors.toList());
iPage.setCurrent(pageable.getCurrent()).setSize(pageable.getSize()).setRecords(result).setTotal(result.size()).setPages(Pageable.getPagation(result.size(), pageable.getSize()));
