LocalDate时间比较

  boolean flag = LocalDate.parse("2023-05-09").isAfter(LocalDate.now().plusDays(4));
  System.out.println("++++++++++++++" + LocalDate.now().minusDays(3));     // 当前时间-3天
  System.out.println("++++++++++++++" + LocalDate.now().plusDays(3));    // 当前时间+3天
  System.out.println("++++++++++++++" + flag);        // true
