java获取某年内工作日、休息日、节假日，返回json

直接上代码

package com.finesdk.util;import com.alibaba.fastjson.JSON;import java.text.SimpleDateFormat;

import java.util.Calendar;

import java.util.List;public class WorkDayUtil {public static class Day{private String dayStr;//类型 0代表上班 1周末休息 2节假日private Integer type;public String getDayStr() {return dayStr;}public void setDayStr(String dayStr) {this.dayStr = dayStr;}public Integer getType() {return type;}public void setType(Integer type) {this.type = type;}}/*** 获取某年内工作日、休息日、节假日** @param year* @return*/private static List<Day> getDates(int year, List<String> holiday, List<String> makeWork) {List<Day> dates = new ArrayList<Day>();SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");for (int i = 1; i <= 12; i++){Calendar cal = Calendar.getInstance();cal.set(Calendar.YEAR, year);cal.set(Calendar.MONTH, i - 1);cal.set(Calendar.DATE, 1);while (cal.get(Calendar.YEAR) == year && cal.get(Calendar.MONTH) < i) {int day = cal.get(Calendar.DAY_OF_WEEK);if ((day == Calendar.SUNDAY || day == Calendar.SATURDAY)) {Date work = (Date) cal.getTime().clone();Day day1 = new Day();day1.setDayStr(sdf.format(work));day1.setType(1);    //休息日for (String hstr:holiday) {if(hstr.equals(sdf.format(work))){day1.setType(2);    //节假日}}for (String wStr:makeWork) {if(wStr.equals(sdf.format(work))){day1.setType(0);    //补班}}dates.add(day1);}else{Date  work = (Date) cal.getTime().clone();Day day1 = new Day();day1.setDayStr(sdf.format(work));day1.setType(0);for (String hstr:holiday) {if(hstr.equals(sdf.format(work))){day1.setType(2);}}dates.add(day1);}cal.add(Calendar.DATE, 1);}}return dates;}public static void main(String[] args) {//节假日List<String> holiday = new ArrayList<>();//补班List<String> makeWork = new ArrayList<>();//元旦holiday.add("2020-01-01");//春节makeWork.add("2020-01-19");holiday.add("2020-01-24");holiday.add("2020-01-25");holiday.add("2020-01-26");holiday.add("2020-01-27");holiday.add("2020-01-28");holiday.add("2020-01-29");holiday.add("2020-01-30");holiday.add("2020-01-31");holiday.add("2020-02-01");holiday.add("2020-02-02");//清明holiday.add("2020-04-04");holiday.add("2020-04-05");holiday.add("2020-04-06");//五一makeWork.add("2020-04-26");holiday.add("2020-05-01");holiday.add("2020-05-02");holiday.add("2020-05-03");holiday.add("2020-05-04");holiday.add("2020-05-05");makeWork.add("2020-05-09");//端午节holiday.add("2020-06-25");holiday.add("2020-06-26");holiday.add("2020-06-27");makeWork.add("2020-06-28");//十一makeWork.add("2020-09-27");holiday.add("2020-10-01");holiday.add("2020-10-02");holiday.add("2020-10-03");holiday.add("2020-10-04");holiday.add("2020-10-05");holiday.add("2020-10-06");holiday.add("2020-10-07");holiday.add("2020-10-08");makeWork.add("2020-10-10");//生成工作日、周末、节假日List<Day> dates = getDates(2020,holiday,makeWork);System.out.println(dates.size());String s = JSON.toJSONString(dates);System.out.println(s);}
}

节假日holiday 和 补班makeWork 需要手动维护。

最后生成json数据如下图：
