今天，小編發(fā)現(xiàn)一篇關(guān)于使用Java來實現(xiàn)獲取國家法定節(jié)假日的小程序，來和大家分享一下。有興趣的小伙伴可以一起來閱讀，嘗試一下。
前言
此節(jié)假日為嚴(yán)格按照國家要求的雙休和法定節(jié)假日并且包含節(jié)假日的補(bǔ)班信息，大家可根據(jù)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

public class TestDate {

//獲取所有的周末

//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(bǔ)班
if (wage.equals(1)) {
monthWekDay.remove(date);
} else {
monthWekDay.add(date);
}
}
return monthWekDay;
}
/**

private static Map getJjr(int year, int month) {
String url = "http://timor.tech/api/holiday/year/";
OkHttpClient client = new OkHttpClient();
Response response;
//解密數(shù)據(jù)
String rsa = null;
Request request = new Request.Builder()
.url(url)
.get()
.addHeader("Content-Type", "application/x-www-form-urlencoded")
.build();
try {
response = client.newCall(request).execute();
rsa = response.body().string();
} catch (IOException e) {
e.printStackTrace();
}
return JSONObject.parseObject(rsa, Map.class);
}
/**
* 獲取周末 月從0開始
*
* @param year
* @param mouth
* @return
*/
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(dāng)然也可以根據(jù)自己的需求自定義。
以下是我自己業(yè)務(wù)需求，將調(diào)用API接口獲取的節(jié)假日信息保存到本地數(shù)據(jù)庫中，如果不感興趣可以跳過以下內(nèi)容哦~~~~
