java格式化时间到毫秒：

public static void main(String[] args) throws ParseException {
            Date date = DateUtils.parseDate("2020-02-06 01:58:00.000020", "yyyy-MM-dd HH:mm:ss.SSSSSS");
            System.out.println( DateFormatUtils.format(date,"yyyy-MM-dd HH:mm:ss.SSSSSS"));
            System.out.println( DateFormatUtils.format(new Date(),"yyyy-MM-dd HH:mm:ss.SSSSSS"));
    
        }
