不能将字符串对象强制转换为日期-时间对象。这些类型是不相关的。
您可以要求日期-时间对象生成文本。
永远不要使用有严重缺陷的遗留日期时间类型，如java.sql.Date。仅使用java.time类。
要从类似于SQL标准类型DATE的列中检索值，请使用java.time.LocalDate。
LocalDate ld = myResultSet.getObject( … , LocalDate.class ) ;
生成标准ISO 8601格式的文本：YYYY-MM-DD。
String output = ld.toString() ;
要生成其他格式的文本，请使用DateTimeFormatter和DateTimeFormatterBuilder类。这些已经被广泛报道，所以搜索了解更多。
