利用DateTimeFormatter 来格式化时间时,报 : Text ‘2018-3-15 00:00:00’ could not be parsed at index 5 异常
Exception in thread "main" java.time.format.DateTimeParseException: Text '2018-3-15 00:00:00' could not be parsed at index 5

原因:当month小于10时,’MM’ 解析失败,前面加上0则解析成功.
public static void main(String[] args) {
getInstants((),15);
}
private static Instant[] getInstants(LocalDate localDate, int day) {
int month = ().getValue();
int year = ();
// String monthStr = month < 10 ? ("0" + month) : month + "";
String monthStr = (month);
String dateStringStart = ("%d-%s-%d 00:00:00", year, monthStr, day);
String dateStringEnd = ("%d-%s-%d 23:59:59", year, monthStr, day);
DateTimeFormatter dateTimeFormatter = ("yyyy-MM-dd HH:mm:ss");
LocalDateTime start = (dateStringStart, dateTimeFormatter);
LocalDateTime end = (dateStringEnd, dateTimeFormatter);
//解析日期
Instant[] instant = new Instant[2];
instant[0] = ((8));
instant[1] = ((8));
return instant;
}
