java - Hibernate-search 无法在映射组件中找到字段

Question

我有一个包含地址的用户类。我已将地址映射为组件。 User 中的 Address 变量定义为 @IndexEmbedded，Address 类本身定义为 @Embeddable。数据库中的用户表也包含地址字段的列。我可以保存用户并确认它确实保存了地址字段。我可以在用户字段中使用 Hibernate 搜索查询进行搜索，这会提供预期的结果。但是，在地址中搜索字段会出现以下错误:

我正在使用以下版本:

• hibernate-4.3.5

不确定这是否有用，但数据库是 MySql 5.6

欢迎任何为我指明解决此问题的正确方向的帮助。我发现了对这样的问题的引用 here ，但从我在那里读到的内容来看，我使用的版本应该修复了该错误。

Answer 1

@IndexedEmbedded 可能在编译类型 Address 上求值，该类型没有 place 属性。 AddressImpl 有，但 hibernate 搜索可能不会查看运行时类型。

一般来说，我不会在实体模型类上使用接口(interface)。

使用 luke，您还可以查看索引并查看哪些字段可用。
