1.jdk8的時間api非常好用责鳍，但是為了與老的Date時間兼容挡鞍，也是非常難受
1).Date -> LocalDate
/**
* Date -> LocalDate
* @param date
* @return
*/
public LocalDate transDateToLocalDate(Date date) {
return date.toInstant().atZone(ZoneId.systemDefault()).toLocalDate();
}
2).Date -> LocalDateTime
/**
* Date -> LocalDateTime
* @param date
* @return
*/
public static LocalDateTime transDateToLocalDateTime(Date date) {
// return date.toInstant().atZone(ZoneId.systemDefault()).toLocalDateTime();
return LocalDateTime.ofInstant(date.toInstant(), ZoneId.systemDefault());
}
3).Date -> LocalTime
/**
* Date -> LocalTime
* @param date
* @return
*/
public LocalTime transDateToLocalTime(Date date) {
return date.toInstant().atZone(ZoneId.systemDefault()).toLocalTime();
}
4).LocalDate->Date
/**
* LocalDate->Date
* @param localDate
* @return
*/
public Date transLocalDateToDate(LocalDate localDate) {
return Date.from( localDate.atStartOfDay(ZoneId.systemDefault()).toInstant());
}
5).LocalDateTime -> Date
/**
* LocalDateTime -> Date
* @param localDateTime
* @return
*/
private Date transLocalDateTimeToDate(LocalDateTime localDateTime) {
return Date.from(localDateTime.atZone(ZoneId.systemDefault()).toInstant());
}
6).LocalTime -> Date
/**
* LocalTime -> Date
* @param localTime
* @return
*/
private Date transLocalTimeToDate(LocalTime localTime) {
return Date.from(LocalDateTime.of(LocalDate.now(),localTime)
.atZone(ZoneId.systemDefault()).toInstant());
}
