SpringBoot如何调用节假日API

RestTemplate配置自行定义

• 工具类

@Slf4j
@Component
public class HolidayUtils {

    @Resource
    private RestTemplate restTemplate;

    private final static String KEY = "http://tool.bitefu.net/jiari?d=";

    public String getHoliday(long baselineDate) {
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd")
                .withZone(ZoneId.systemDefault());
        String format = formatter.format(Instant.ofEpochMilli(baselineDate));
        String url = String.format("%s%s", KEY, format);
        URI uri = URI.create(url);
        String response = restTemplate.getForObject(uri,String.class);
        return HolidayEnum.getHolidayValue(response);
    }
}

• 返回值对应枚举

@Getter
@AllArgsConstructor
public enum HolidayEnum {

    //工作日
    WEEKDAY("0", "Weekday"),

    //周末
    WEEKEND("1", "Weekend"),

    //节假日
    HOLIDAY("2", "Holiday");

    private final String key;

    private final String value;
}
