问题解决
解决⽅案：先将⽂本字符串⽇期转化为LocalDate类型，再将LocalDate转化为LocalDateTime
LocalDateTimeUtils.parseStringToLocalDateTime(
/**
java时间日期格式转换
* 解析字符串为⽇期
* <p>
* 说明：
* 1. 该⽅法主要解决yyyy-MM-dd格式⽂本字符串⽆法直接转换为LocalDateTime的问题
*
* @param source  需要解析的⽇期字符串
* @param formatPattern ⽇期格式化模式
* @return 格式化后的⽇期
*/
public static LocalDateTime parseStringToLocalDateTime(String source, String formatPattern) {
DateTimeFormatter dateTimeFormatter = DateTimeFormatter.ofPattern(formatPattern);
LocalDate localDate = LocalDate.parse(source, dateTimeFormatter);
return localDate.atStartOfDay();
}
java.time.LocalDate.atStartOfDay()⽅法将此⽇期与午夜时间组合在⼀起，以便在此⽇期开始时创建LocalDateTime
