JAVA 利用時間戳來判斷TOKEN是否過時

import java.time.Instant;
import java.time.LocalDateTime;
import java.time.ZoneId;
import java.time.ZoneOffset;
import java.time.format.DateTimeFormatter;

public class Demo01 {
    public static void main(String[] args) {
        LocalDateTime localDateTimeNow = LocalDateTime.now();
        System.out.println(DateUtils.formatDateToParse(DateUtils.localDateTimeConvertDate(localDateTimeNow),DateUtils.DATE_FORMART_YYYY_MM_DD_HH_MM_SS));
        Long milliSecond = getTimestampOfDateTime(localDateTimeNow);
        milliSecond = milliSecond + (7200L * 1000L);
        LocalDateTime dateTime = getDateTimeOfTimestamp(milliSecond);
        System.out.println(DateUtils.formatDateToParse(DateUtils.localDateTimeConvertDate(dateTime),DateUtils.DATE_FORMART_YYYY_MM_DD_HH_MM_SS));
    }
    public static long getTimestampOfDateTime(LocalDateTime localDateTime) {
        ZoneId zone = ZoneId.systemDefault();
        Instant instant = localDateTime.atZone(zone).toInstant();
        return instant.toEpochMilli();
    }
    public static LocalDateTime getDateTimeOfTimestamp(long timestamp) {
        Instant instant = Instant.ofEpochMilli(timestamp);
        ZoneId zone = ZoneId.systemDefault();

    }
}

每每在開發過程當中，交互時，須要頭部設置TOKEN，而這個TOKEN的有效期，該如何設置？以上的案例只是婉轉的舉例說明，7200 * 1000 表明兩個小時，具體的算法是 1*60*60*2，而一秒的等於1000，以上引用了DateUtils,能夠參考http://www.javashuo.com/article/p-vyqqbxam-gm.html
