Java8 Date与LocalDate互转

Java8 日期时间API,新增了LocalDate、LocalDateTime、LocalTime等线程安全类,接下来要说的是LocalDate与java.util.Date之间的转换。

1、LocalDate不包含时间,描述的是日期,如果对时间不关心,可以使用LocalDate

2、Date转LocalDate

    public static void main(String[] args) { Date date = new Date(); LocalDate localDate = LocalDate.now(); LocalDateTime localDateTime = LocalDateTime.now(); System.out.println("date2LocalDate:"+date2LocalDate(date)); } /** * Date转LocalDate * @param date */ public static LocalDate date2LocalDate(Date date) { if(null == date) { return null; } return date.toInstant().atZone(ZoneId.systemDefault()).toLocalDate(); }

控制台输出:

date2LocalDate:2018-06-28

3、LocalDate转Date

    public static void main(String[] args) { Date date = new Date(); LocalDate localDate = LocalDate.now(); LocalDateTime localDateTime = LocalDateTime.now(); System.out.println("localDate2Date:"+localDate2Date(localDate)); }     /** * LocalDate转Date * @param localDate * @return */ public static Date localDate2Date(LocalDate localDate) { if(null == localDate) { return null; } ZonedDateTime zonedDateTime = localDate.atStartOfDay(ZoneId.systemDefault()); return Date.from(zonedDateTime.toInstant()); }

控制台输出:

localDate2Date:Thu Jun 28 00:00:00 CST 2018
