/** * 利用subList办法进行分页 * * @param list        分页数据 * @param pagesize    页面大小 * @param currentPage 以后页面 */private List pageBySubList(List list, int pagesize, int currentPage) {    int totalcount = list.size();    int pagecount = 0;    List<String> subList;    int m = totalcount % pagesize;    if (m > 0) {        pagecount = totalcount / pagesize + 1;    } else {        pagecount = totalcount / pagesize;    }    if (m == 0) {        subList = list.subList((currentPage - 1) * pagesize, pagesize * (currentPage));    } else {        if (currentPage == pagecount) {            subList = list.subList((currentPage - 1) * pagesize, totalcount);        } else {            subList = list.subList((currentPage - 1) * pagesize, pagesize * (currentPage));        }    }    return subList;}
