LocalDate、LocalTime、LocalDateTime类是Java1.8开始对时间类进行的一次大更新,它是在java.time包中,功能十分强大。 LocalDate:用来获取日期格式(年月日) LocalTime:用来获取时间格式(时分秒) LocalDateTime:用来获取日期+时间的格式 LocalDate localDate = LocalDate.now(); LocalTime localTime = LocalTime.now()...

在平常时开发过程中,总有很多奇奇怪怪的时间需要互相转换,比如 Date to String , Date to DateTime , String to Date , String to DateTime ,Date to TimeStamp等等……,中间就算对JavaApi再熟悉也难免会搞混,还不如做一些简单的记录,方便日后需要用到之时直接复制出来使用即可。
