需求要对集合List<Map<String,Object>>进行一个分页：
/**
* 利用subList方法进行分页
*
* @param list 分页数据
* @param pagesize 页面大小
* @param currentPage 当前页面(从0开始计算)
*/
public static List<Map<String,Object>> pageBySubList(List list, int pagesize, int currentPage) {
List<Map<String,Object>> subList = new ArrayList<>();
try {
int totalcount = list.size();
currentPage = currentPage + 1;
int pagecount = 0;
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));
}
}
} catch (Exception e) {
}
return subList;
}
