LocalDate、LocalDateTime与timestamp、Date的转换

LocalDate转Date

LocalDate nowLocalDate = LocalDate.now(); Date date = Date.from(nowLocalDate.atStartOfDay(ZoneId.systemDefault()).toInstant()) 

LocalTime转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); } 

LocalDateTime转Date

LocalDateTime localDateTime = LocalDateTime.now(); Date date = Date.from(localDateTime.atZone(ZoneOffset.ofHours(8)).toInstant()); 

Date转LocalDateTime(LocalDate)

Date date = new Date(); LocalDateTime localDateTime = date.toInstant().atZone(ZoneOffset.ofHours(8)).toLocalDateTime(); LocalDate localDate = date.toInstant().atZone(ZoneOffset.ofHours(8)).toLocalDate(); 

LocalDate转时间戳

LocalDate localDate = LocalDate.now(); long timestamp = localDate.atStartOfDay(ZoneOffset.ofHours(8)).toInstant().toEpochMilli(); 

LocalDateTime转时间戳

LocalDateTime localDateTime = LocalDateTime.now(); long timestamp = localDateTime.toInstant(ZoneOffset.ofHours(8)).toEpochMilli(); 

时间戳转LocalDateTime(LocalDate)

long timestamp = System.currentTimeMillis(); LocalDate localDate = Instant.ofEpochMilli(timestamp).atZone(ZoneOffset.ofHours(8)).toLocalDate(); LocalDateTime localDateTime = Instant.ofEpochMilli(timestamp).atZone(ZoneOffset.ofHours(8
