使用 Hibernate 持久化 List>

我有以下 Java 集合，

List<Map<String, Object>>

我编写了一个自定义转换器类，它可以将其扁平化为 MyEntity 列表（其中 MyEntity 基本上是 String、Value、Java 类型，父集合）并将其重新组装回一个 Map，但我想知道……

是否可以注释该列表，以便 Hibernate 可以保留这些映射的列表？我简要查看了 collectionOfElements 注释，我知道由于 Hibernate 需要转换为有效的数据库类型，因此 Object 值会出现问题。

任何想法都感激不尽:)

I have the following Java Collection

List<Map<String, Object>>

I've written a custom converter class which can flatten this down to a List of MyEntity (where MyEntity is basically String, Value, Java type, parent collection) and re-assemble it back to a Map but I was wondering......

Is it possible to annotate the List such that Hibernate can persist a List of these Maps? I've had a brief look at the collectionOfElements annotation and I know there will be problems with the Object value due to Hibernate needed to convert to a valid database type.

Any ideas gratefully received :)
