Spring Data Neo4j 5 的 EntityScan 在使用 Kotlin 时包含伴随对象
Spring Data Neo4j 5's EntityScan includes companion objects when using Kotlin
我正在通过 Spring Boot 2.0.0.M4 使用 Spring Data 5。
我注意到在使用 @EntityScan 并提供包时，它包括扫描由 Kotlin 生成的 'inner' 类。在我下面的示例中，我只有一个 属性，但我也尝试了 companion object { <property here> }，但它仍然出错。
有没有办法过滤掉 Kotlin 生成的这些内部 类？
这是我得到的异常：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'neo4jMappingContext': Invocation of init method failed; nested exception is java.lang.UnsupportedOperationException: This class is an internal synthetic class generated by the Kotlin compiler, such as an anonymous class for a lambda, a SAM wrapper, a callable reference, etc. It's not a Kotlin class or interface, so the reflection library has no idea what declarations does it have.

此问题已在 Kay 版本中修复。

此问题已在 Kay 版本中修复。 参见 https://jira.spring.io/browse/DATACMNS-1171。 这似乎也与描述 here.
的科特林错误有关升级到 Spring Boot 2.0.0.M5 解决了这个问题。
