LocalDateTime使用记录

java8新增LocalDateTime类，相比SimpleDateFormat好用很多

LocalDateTime localDateTime = LocalDateTime.now();
        DateTimeFormatter dateTimeFormatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm");
        String startTime = dateTimeFormatter.format(localDateTime.minusMinutes(5));
        String endTime = dateTimeFormatter.format(localDateTime);
        
        System.out.println(startTime);
        System.out.println(endTime);

输出
