public static void main(String[] args) { int MAX_SEND = 500; List list = new ArrayList<>(); for(int i=0;i<1000;i++){ list.add(i); int limit = (list.size() + MAX_SEND - 1) / MAX_SEND; List> mglist = new ArrayList<>(); Stream.iterate(0, n -> n + 1).limit(limit).forEach(i -> { mglist.add(list.stream().skip(i * MAX_SEND).limit(MAX_SEND).collect(Collectors.toList())); List> splitList = Stream.iterate(0, n -> n + 1).limit(limit).parallel().map(a -> list.stream().skip(a * MAX_SEND).limit(MAX_SEND).parallel().collect(Collectors.toList())).collect(Collectors.toList()); for(List list1:splitList){ System.out.println("---------------------------------------------"); System.out.println(JSON.toJSONString(list1));

方法2 :直接使用公共方法操作

        List<List<Map<String,Object>>> lists = ListUtils.partition(editList,1000);
        for(List<Map<String,Object>> sublist: lists){
            //todo sublist
