我遇到了一个问题,即我不能坚持使用Hibernate的Map<UUID, Integer>。 我不敢确定如何适当注意到这一收集,以便适当将其绘制成我们的数据库。 我们控制了图谋,因此,任何工作都将受到罚款。 我是否需要具体说明关键用户如何在我的地图上? 我是否需要? 我知道每个领域使用的是类型说明。 也许不是收集? 我在请<代码>session.flush()时收到以下例外情况。
java.lang.ClassCastException: java.lang。 不能 Str。 UUID
@ElementCollection
@Type(type="org.hibernate.type.UUIDCharType")
private Map<UUID, Boolean> orderCount = new HashMap<UUID, Integer>();
I believe you will have to write a UserType to handle Map<UUID, Boolean> .. This UserType should then use org.hibernate.type.UUIDCharType to map the key column.
