2021-09-01 LocalDateTime用法

LocalDateTime只获取年月日

//获取当前时间
LocalDateTime localDateTime = LocalDateTime.now();

localDateTime.format(DateTimeFormatter.ofPattern(“yyyy-MM-dd”)

字符串传LocalDateTime
LocalDateTime localDateTime = LocalDateTime.parse(“2021-01-28 13:12:11”, DateTimeFormatter.ofPattern(“yyyy-MM-dd HH:mm:ss”));
