对list进行分页_domain 对象中list属性如何分页显示

package com.demo.domain.utils;
 
import com.alibaba.fastjson.JSONObject;
import com.google.common.collect.Lists;
 
import java.util.ArrayList;
import java.util.List;
import java.util.stream.Collectors;
 
/**

public class ListUtils {
 
    /**

     * @Date 2022/3/10 11:01
     * @Param [nlist, pageNum]
     * @return
     **/
    public static <T> List<List<T>> getPageData(List<T> nlist, int pageNum) {
        if (nlist == null || nlist.size() == 0) {
            return null;
        }
        List<List<T>> result = new ArrayList<>();
        if (pageNum < 1) {
            result.add(nlist);
            return result;
        }
 
        for (int i = 0; i < Math.ceil((double)nlist.size() / pageNum); i++) {
            List<T> tempList = nlist.stream().skip(i * pageNum).limit(pageNum).collect(Collectors.toList());
            result.add(tempList);
        }
        return result;
    }
 
    public static void main(String[] args) {
        List<String> list = Lists.newArrayList("1","2","3","4","5","6","7","8","9");
        List<List<String>> pageData = getPageData(list, 3);
        for (List<String> data : pageData) {
            System.out.println(JSONObject.toJSONString(data));
        }
    }
 
}

运行main方法：

["1","2","3"]
["4","5","6"]
["7","8","9"]
