我是靠谱客的博主直率狗，最近开发中收集的这篇文章主要介绍LocalDate与Date转化01. java.util.Date --> java.time.LocalDateTime 02. java.util.Date --> java.time.LocalDate 03. java.util.Date --> java.time.LocalTime 04. java.time.LocalDateTime --> java.util.Date 05. java.time.LocalDate --> java.util.Date 06. java.t，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

01. java.util.Date --> java.time.LocalDateTime

 public void uDateToLocalDateTime() {
        java.util.Date date = new java.util.Date();
        Instant instant = date.toInstant();
        ZoneId zone = ZoneId.systemDefault();
        LocalDateTime localDateTime = LocalDateTime.ofInstant(instant, zone);
}

02. java.util.Date --> java.time.LocalDate

 public void uDateToLocalDate() {
        java.util.Date date = new java.util.Date();
        Instant instant = date.toInstant();
        ZoneId zone = ZoneId.systemDefault();
        LocalDateTime localDateTime = LocalDateTime.ofInstant(instant, zone);
        LocalDate localDate = localDateTime.toLocalDate();
 }

03. java.util.Date --> java.time.LocalTime

public void uDateToLocalTime() {
        java.util.Date date = new java.util.Date();
        Instant instant = date.toInstant();
        ZoneId zone = ZoneId.systemDefault();
        LocalDateTime localDateTime = LocalDateTime.ofInstant(instant, zone);
        LocalTime localTime = localDateTime.toLocalTime();
}

04. java.time.LocalDateTime --> java.util.Date

public void localDateTimeToUdate() {
        LocalDateTime localDateTime = LocalDateTime.now();
        ZoneId zone = ZoneId.systemDefault();
        Instant instant = localDateTime.atZone(zone).toInstant();
        java.util.Date date = Date.from(instant);
}

05. java.time.LocalDate --> java.util.Date

public void localDateToUdate() {
        LocalDate localDate = LocalDate.now();
        ZoneId zone = ZoneId.systemDefault();
        Instant instant = localDate.atStartOfDay().atZone(zone).toInstant();
        java.util.Date date = Date.from(instant);
}

06. java.time.LocalTime --> java.util.Date

public void LocalTimeToUdate() {
        LocalTime localTime = LocalTime.now();
        LocalDate localDate = LocalDate.now();
        LocalDateTime localDateTime = LocalDateTime.of(localDate, localTime);
        ZoneId zone = ZoneId.systemDefault();
        Instant instant = localDateTime.atZone(zone).toInstant();
        java.util.Date date = Date.from(instant);
}

示例如下：

   /**
     * String日期时间转换 LocalTime
     * @param strDateTime  2018-09-28 17:07:05
     * @return
     */
    public static LocalTime strDateTime2LocalTime(String strDateTime){
        LocalTime localTime = null;
        if (!StringUtils.isEmpty(strDateTime)){
            SimpleDateFormat df =new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
            try {
                Date date = df.parse(strDateTime);
                System.out.println("时间："+ date);
                Instant instant = date.toInstant();
                ZoneId zone = ZoneId.systemDefault();
                LocalDateTime localDateTime = LocalDateTime.ofInstant(instant, zone);
                localTime = localDateTime.toLocalTime();
                System.out.println(localTime);
            } catch (ParseException e) {
                e.printStackTrace();
            }
        }
        return localTime;
    }
