写了一个手动分页的功能，可以直接用，分享一下

/*
currentPage: 当前页数
pageSize：每页条数
list：要执行分页的数组 
*/
public static <T> PageInfo<T> getPageInfo(int currentPage, int pageSize, List<T> list) {
        int total = list.size();
        if (total > pageSize) {
            int toIndex = pageSize * currentPage;
            if (toIndex > total) {
                toIndex = total;
            }
            int totalPage = total % pageSize == 0 ? (total/pageSize) : (total/pageSize)+1;
            if (totalPage < currentPage){
                list = new ArrayList<>();
            }else {
                list = list.subList(pageSize * (currentPage - 1), toIndex);
            }
        }
        Page<T> page = new Page<>(currentPage, pageSize);
        page.addAll(list);
        page.setPages((total + pageSize - 1) / pageSize);
        page.setTotal(total);

        return new PageInfo<>(page);
}
