在Hibernate 6.2中使用Java-Records作为@Embeddable

Hibernate 6.2 introduced support for Java records用于@Embeddable。（所以这个问题不是Using Java records as JPA embeddables的重复）。
但是，我不能让它与Sping Boot 3.1一起工作。Hibernate确实有一个测试用例，所以它应该确实是可能的。

@Entity(name = "MyEntity")
public class MyEntity {
    @Id
    Long id;

    @Embedded
    MyRecord record;

    public MyEntity() {}

    public MyEntity(Long id, MyRecord record) {
        this.id = id;
        this.record = record;
    }

    public Long getId() {
        return id;
    }

    public MyRecord getRecord() {
        return record;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public void setRecord(MyRecord record) {
        this.record = record;
    }
}

@Embeddable
public static record MyRecord(String name, String description) {}
}

@Repository
public interface MyEntityRepository extends JpaRepository<MyEntity, Long> {}

调用MyEntityRepository.save()将给予以下异常：

有一个开放的Bug HHH-16759解决了这个问题。目前，此功能仅适用于EntityManager.persist()，而EntityManager.merge()正在被Sping Boot 调用。一旦问题得到解决，它应该可以按预期工作。
