我正在使用 Joda Time 和 Jadira 用户类型库将 Joda LocalTime 保存在我的数据库中。
这是我的实体

正如您在堆栈末尾看到的那样，有
Caused by: org.hibernate.PropertyAccessException: could not set a field value by reflection setter of com.flightfaq.beans.business.Airport.closingTime
但是也
Can not set org.joda.time.LocalTime field com.flightfaq.beans.business.Airport.closingTime to org.joda.time.LocalTime
这是我用来在数据库中输入有问题的机场的 SQL 命令
INSERT INTO `Airport` (`id`, `altitude`, `arrTimeOffset`, `category`, `closingTime`, `comments`, `depTimeOffset`, `latitude`, `longitude`, `nameIATA`, `nameOACI`, `openingTime`, `ssliaLevel`, `taxiTime`) VALUES
(1, 499, '0', 'A', '00:00:00', 'se garer au parking R12', '15', '433806N', '0012204E', 'TLS', 'LFBO', '00:00:00', 4, '0');
我输入了“00:00:00”作为关闭时间。
