1.LocalDate转Date

date = LocalDate.of(2006,07,26);
        ZoneId zone = ZoneId.systemDefault();
        Instant instant = date.atStartOfDay().atZone(zone).toInstant();
        java.util.Date da = Date.from(instant);

2.Date转LocalDate

=new Date().toInstant();
           ZoneId zone = ZoneId.systemDefault();
           LocalDateTime localDateTime = LocalDateTime.ofInstant(instant, zone);
           LocalDate localDate= localDateTime.toLocalDate();
