        <h4>1.LocalDate转Date</h4>

LocalDate nowLocalDate = LocalDate.now();

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

2.LocalDateTime转Date

LocalDateTime localDateTime = LocalDateTime.now();

Date date = Date.from(localDateTime.atZone(ZoneId.systemDefault()).toInstant());

3.Date转LocalDateTime(LocalDate)

Date date = new Date();

LocalDateTime localDateTime = date.toInstant().atZone(ZoneId.systemDefault()).toLocalDateTime();

LocalDate localDate = date.toInstant().atZone(ZoneId.systemDefault()).toLocalDate();

4.LocalDate转时间戳

LocalDate localDate = LocalDate.now();

long timestamp = localDate.atStartOfDay(ZoneId.systemDefault()).toInstant().toEpochMilli();

5.LocalDateTime转时间戳

LocalDateTime localDateTime = LocalDateTime.now();

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

6.时间戳转LocalDateTime(LocalDate)

long timestamp = System.currentTimeMillis();

LocalDate localDate = Instant.ofEpochMilli(timestamp).atZone(ZoneId.systemDefault()).toLocalDate();

LocalDateTime localDateTime = Instant.ofEpochMilli(timestamp).atZone(ZoneId.systemDefault()).toLocalDateTime();
