Spring Data Neo4j 5的EntityScan在使用Kotlin时包含了伴随对象

我通过Spring Boot 2.0.0.M4使用Spring Data 5。

我注意到当使用@EntityScan并提供一个包时，它包括扫描由Kotlin生成的“内部”类。 在我的例子中，我只有一个属性，但我也尝试过companion object { <property here> } ，它仍然出错。

是否有过滤掉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. Please use Java reflection to inspect this class: class com.mybusinessincorp.mbitest.model.Store$properties$3

Full Stacktrace：

Answer 1

这个问题已经在Kay版本中解决了。 请参阅https://jira.spring.io/browse/DATACMNS-1171 。 这似乎也与这里描述的一个kotlin错误有关。

升级到Spring Boot 2.0.0.M5修复了这个问题。
