教你怎麼用Java獲取國傢法定節假日

Posted on by

前言

此節假日為嚴格按照國傢要求的雙休和法定節假日並且包含節假日的補班信息，大傢可根據自己的需求自定義處理哦。

以下為Maven配置，是程序用到的依賴。版本的話，可以用最新的。

Maven配置

<!-- okhttp -->
        <dependency>
            <groupId>com.squareup.okhttp</groupId>
            <artifactId>okhttp</artifactId>
            <version>${okhttp.version}</version>
        </dependency>
 
        <!-- fastjson -->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>${fastjson.version}</version>
        </dependency>

public class TestDate {
 
    public static void main(String[] args) {
        System.out.println(getJjr(2021, 4));
        System.out.println(getMonthWekDay(2021, 4));

    }
 
    /**

        //http://timor.tech/api/holiday api文檔地址
        Map jjr = getJjr(year, month + 1);
        Integer code = (Integer) jjr.get("code");
        if (code != 0) {
            return monthWekDay;
        }
        Map<String, Map<String, Object>> holiday = (Map<String, Map<String, Object>>) jjr.get("holiday");
        Set<String> strings = holiday.keySet();
        for (String str : strings) {
            Map<String, Object> stringObjectMap = holiday.get(str);
            Integer wage = (Integer) stringObjectMap.get("wage");
            String date = (String) stringObjectMap.get("date");
            //篩選掉補班
            if (wage.equals(1)) {
                monthWekDay.remove(date);
            } else {
                monthWekDay.add(date);

        }
        return JSONObject.parseObject(rsa, Map.class);
    }
 
    /**

    public static Set<String> getMonthWekDay(int year, int mouth) {
        Set<String> dateList = new HashSet<>();
        SimpleDateFormat simdf = new SimpleDateFormat("yyyy-MM-dd");
        Calendar calendar = new GregorianCalendar(year, mouth, 1);
        Calendar endCalendar = new GregorianCalendar(year, mouth, 1);
        endCalendar.add(Calendar.MONTH, 1);
        while (true) {
            int weekday = calendar.get(Calendar.DAY_OF_WEEK);
            if (weekday == 1 || weekday == 7) {
                dateList.add(simdf.format(calendar.getTime()));
            }
            calendar.add(Calendar.DATE, 1);
            if (calendar.getTimeInMillis() >= endCalendar.getTimeInMillis()) {
                break;
            }
        }
        return dateList;
    }
 
}

以上方法可以拿來即用，當然也可以根據自己的需求自定義。

以下是我自己業務需求，將調用API接口獲取的節假日信息保存到本地數據庫中，如果不感興趣可以跳過以下內容哦~~~~
