1缎脾、將long類型的時間字符串，如：newDate().getTime()遗菠，轉化為“yyyy-MM-dd HH:mm:ss”格式的字符串
public static String longStrToDateStr(String time) {
????????SimpleDateFormat simpleDateFormat =newSimpleDateFormat("yyyy-MM-dd HH:mm:ss");
????????return simpleDateFormat.format(newDate(newLong(time)));
}
2华蜒、將“yyyy-MM-dd HH:mm:ss”格式的時間字符串，轉化為long類型的時間字符串
public static String dateStrToLongStr(String time)throwsParseException {
????????SimpleDateFormat simpleDateFormat =newSimpleDateFormat("yyyy-MM-dd HH:mm:ss");
????????Date date = simpleDateFormat.parse(time);
????????return String.valueOf(date.getTime());
}
