SimpleDateFormat时间不对&LocalDate和LocalDateTime的区别

private static final DateTimeFormatter SECOND_FORMATTER = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
private static final DateTimeFormatter DAY_FORMATTER = DateTimeFormatter.ofPattern("yyyy-MM-dd");
// 解析字符串为日期
String dateStr = "1990-01-01";
LocalDate dateTime = LocalDate.parse(dateStr, DAY_FORMATTER);
