java displays 1 second ago, 1 minute ago, 2 minutes ago, 3 days ago

Display the time. If the difference from the current time is less than one day, it will automatically use ** seconds (minutes, hours) ago. If it is greater than one day, it will display in the format specified by format

	 *            时间
	 * @param format
	 *            格式 格式描述:例如:yyyy-MM-dd yyyy-MM-dd HH:mm:ss
	 * @return

You can expand here to meet your specific needs~~

public static void main(String[] args) {
try{
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
System.out.println(showTime(df.parse("2015-02-27 11:31:00"),"yyyy-MM-dd HH:mm:ss"));
}catch (Exception e) {
// TODO: handle exception
}
