LocalDateTime相关处理，得到零点以及24点值，最近五分钟点位，与Date互转，时间格式

最近一直使用LocalDateTime，老是忘记怎么转换，仅此记录一下

import java.time.Instant;

import java.time.LocalDateTime;

import java.time.LocalTime;

import java.time.ZoneId;

import java.time.format.DateTimeFormatter;

import java.util.Date;

public class Test {

    public static void main(String[] args) {

        LocalDateTime now = LocalDateTime.now();

        System.out.println("当前时间:  "+now);

        //时间格式

        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");

        System.out.println("formate: "+ now.format(formatter));

        //当天的零点

        System.out.println("当天的零点:  "+LocalDateTime.of(now.toLocalDate(), LocalTime.MIN));

        //当天的最后时间

        System.out.println("当天的最后时间:  "+LocalDateTime.of(now.toLocalDate(), LocalTime.MAX));

        //最近的五分钟点位

        Integer minute = now.getMinute();

        minute = minute/5*5;

        System.out.println("最近的五分钟点位:  "+LocalDateTime.of(now.getYear(), now.getMonth(), now.getDayOfMonth(), now.getHour(), minute, 0));

        //Date转为LocalDateTime

        Date date = new Date();

        Instant instant = date.toInstant();

        ZoneId zoneId = ZoneId.systemDefault();

        System.out.println("Date转为LocalDateTime: "+instant.atZone(zoneId).toLocalDateTime());

    }

}
