1.LocalDateTime以及DateTimeFormatter

public static void main(String[] args) {
	LocalDate date = LocalDate.now();
	LocalTime time = LocalTime.now();
	LocalDateTime dateTime = LocalDateTime.now();
	System.out.println(date);    //2020-05-21
	System.out.println(time);    //18:54:01.650
	System.out.println(dateTime);//2020-05-21T18:54:01.650
	
	DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
	//字符串转LocalDateTime
	dateTime = LocalDateTime.parse("2020-02-23 11:23:55",formatter);
	//LocalDateTime转字符串
	System.out.println(dateTime.format(formatter));//2020-02-23 11:23:55
}
