【问题描述】：
我正在使用 Spring 框架提供的 @DateTimeFormat 注释从 URL 参数解析字符串到日期，但无法使用这种格式进行解析：" MM-dd-yyyykk:mm:ss"
例如。 “01-14-202100:40:30”、“01-14-202100:44:07”、“01-14-202100:49:00”...
得到以下异常。
org.springframework.web.method.annotation.MethodArgumentTypeMismatchException: Failed to convert value of type 'java.lang.String' to required type 'java.util.Date'; nested exception is org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.lang.String] to type [@org.springframework.web.bind.annotation.PathVariable @org.springframework.format.annotation.DateTimeFormat java.util.Date] for value '01-14-202100:40:30'; nested exception is java.lang.IllegalArgumentException: Parse attempt failed for value [01-14-202100:40:30]

错误消息说您正在使用
java.util.Date。不。该课程设计不良且早已过时。而是使用来自java.time, the modern Java date and time API 的LocalDateTime。
