将List用Page进行分页

@Data
public class RequestPage {
    private int page;
    private int size;
    

    /**
     * 初始化分页参数
     */
    public RequestPage(Integer page, Integer size) {
        this.page = page == null || page < 1 ? 0 : page - 1;
        this.size = size == null || size < 1 ? 20 : size;
    }

    /**
     * 对List进行分页处理
     *
     * @param list     list数据集合
     * @param pageable 分页信息
     * @param <T>
     * @return
     */
    public static <T> Page<T> listConvertToPage(List<T> list, Pageable pageable) {
        int start = pageable.getOffset();
        int end = (start + pageable.getPageSize()) > list.size() ? list.size() : (start + pageable.getPageSize());
        return new PageImpl<T>(list.subList(start, end), pageable, list.size());
    }
}

使用：
public Response getInPutOutPut(Integer page, Integer size, Integer warehouseId, Integer applicationType, String startDate, String endDate) {
        List<Application> applications = warehouseService.getInPutOutPut(warehouseId, applicationType, startDate, endDate);
        if (applications != null && applications.size() > 0) {
            RequestPage requestPage = new RequestPage(page, size);
            Pageable pageable = new PageRequest(requestPage.getPage(), requestPage.getSize(), Sort.Direction.DESC, "createDate");
            Page<Application> applicationPage = RequestPage.listConvertToPage(applications, pageable);
            return ResponseUtil.success(applicationPage);
        }
        return ResponseUtil.error(ReturnMsg.NO_DATA);
    }
