stream分页

List<AccessAreaVo> areaVo = vos.stream()
.skip(pageable.getPageSize() * (pageable.getPageNumber() - 1))
.limit(pageable.getPageSize()).collect(Collectors.toList());

 

阿里巴巴nacos源码里面的分页

services = doPage(services, pageNo - 1, pageSize);

private Collection<Service> doPage(Collection<Service> services, int pageNo, int pageSize) {
        if (services.size() < pageSize) {
            return services;
        }
        Collection<Service> result = new LinkedList<>();
        int i = 0;
        for (Service each : services) {
            if (i++ < pageNo * pageSize) {
                continue;
            }
            result.add(each);
            if (result.size() >= pageSize) {
                break;
            }
        }
        return result;
    }

final int startRow = (pageNo - 1) * pageSize;

selectSql = sqlFetchRows + " LIMIT " + startRow + "," + pageSize;

//处理逻辑分页
        List<AnalysisVehicleDuringDayVO> analysisVehicleDuringDayVOS = dayVOList.stream()
                .skip(activityFrequencyParamDTO.getPageSize() * (activityFrequencyParamDTO.getPageNo() - 1))
                .limit(activityFrequencyParamDTO.getPageSize()).collect(Collectors.toList());
        searchCarVOPage.setRecords(analysisVehicleDuringDayVOS).setCurrent(activityFrequencyParamDTO.getPageNo()).setSize(activityFrequencyParamDTO.getPageSize())
                .setTotal(dayVOList.size());
        int totalPage = (dayVOList.size() + activityFrequencyParamDTO.getPageSize() - 1) / activityFrequencyParamDTO.getPageSize();
        searchCarVOPage.setPages(totalPage);
