我正在尝试从Spring Boot 2.7迁移到Spring Boot 3.0。
我的实体使用Joined继承类型和抽象超类类型的JpaRepository，它们处于一个等级关系中。自从迁移以来，当我尝试在JpaRepository上运行方法findByKey（）时，我的集成测试失败，如下面的例子所示：

在调试代码时，我发现Hibernate试图将子类的属性设置为抽象超类EntityMetamodel，但失败了。为了在Hibernate 6中工作，应该做哪些更改？
实体层次结构：
x一个一个一个一个x一个一个二个一个x一个一个三个一个
Jpa存储库

public interface JpaRequestRepository extends JpaRepository<JpaRequest, Long> {

    JpaRequest findByKey(String key);
