方法一:通过String.substring()方法将最后的三位去掉
1/** 2 * 获取精确到秒的时间戳 3 * @return 4 */ 5public static int getSecondTimestamp(Date date){ if (null == date) { return 0; } String timestamp = String.valueOf(date.getTime()); int length = timestamp.length(); if (length > 3) { return Integer.valueOf(timestamp.substring(0,length-3)); } else { return 0; } }
方法二:通过整除将最后的三位去掉
1/** 2 * 获取精确到秒的时间戳 3 * @param date 4 * @return 5 */ 6public static int getSecondTimestampTwo(Date date){ if (null == date) { return 0; } String timestamp = String.valueOf(date.getTime()/1000); return Integer.valueOf(timestamp); }
