我有四个实体 RoomNight、BookingCorporateDetails、BookingDiscountDetails 和 BookingDetails，其中 BookingCorporateDetails、BookingDiscountDetails 和 BookingDetails 引用列 (room_night_booking_id) 上的 RoomNight。
我正在尝试在 BookingCorporateDetails、BookingDiscountDetails 和 BookingDetails 上创建外键联接，以便一起保存/获取/删除所有数据。我能够将数据保存到数据库中，但是当我尝试检索时，我得到 Hibernate PropertyAccessException。实体表结构为-

PS:我在 MySQL 5.7 上使用 Spring Data JPA 1.10.7.RELEASE 和 Hibernate 5.1.0.Final。
最佳答案
检查 RoomNightEntity 表中 room_night_booking_id 列的类型(room_night 如果我能正确看到它)。它不应该是数字类型。
看起来Java尝试将类解析为Long，然后尝试将Long分配给String属性。
关于java - 一对一映射期间的 Hibernate PropertyAccessException，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/42175538/
