Java8常用日期格式化&字符串日期相互转换

 LocalDateTime localDateTime=LocalDateTime.now();    //格式化日期时间类型为字符串    DateTimeFormatter dateTimeFormatter=DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");    String ss = dateTimeFormatter.format(localDateTime).toString();    System.out.println(ss);    //日期时间字符串类型转 LocalDateTime    DateTimeFormatter df = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");    LocalDateTime yy = LocalDateTime.parse("2017-09-28 21:22:33", df);    System.out.println(yy);    //日期字符串转日期类型    LocalDate localDate=LocalDate.parse("2019-12-10",DateTimeFormatter.ofPattern("yyyy-MM-dd"));    System.out.println(localDate.toString());}
