尝试使用 Spring Data JPA 创建自定义存储库时，未找到类型错误的属性

我有一个媒体实体，其中包含用户上传的文件的一些基本字段。为了保存上传文件的字节，我想创建一个包含该功能的自定义存储库。按照Spring文档中的步骤，我创建了一个如下所示的界面：

public interface MediaBytesRepository
{
    public byte[] getBytes(Media media) throws IOException;
    public void saveBytes(Media media, byte[] bytes) throws IOException;
    public void appendBytes(Media media, byte[] bytes) throws IOException;
    public void deleteBytes(Media media) throws IOException;
    public boolean bytesExist(Media media) throws IOException;
}

然后，我为这个接口提供了一个实现，称为MediaBytesRepositoryImpl

有了这个，然后我创建了以下界面：

public interface MediaRepository extends JpaRepository<Media, Long>, MediaBytesRepository
{
}

现在，当我启动服务器时，我得到以下堆栈跟踪：

我发现了这篇类似的帖子，但那里的建议（都在同一个包中，命名约定）是我已经在做的事情。我所有的媒体类和接口都在同一个包中，我使用的是“Impl”后缀。

有人可以解释为什么我得到这个错误，以及我如何解决它吗？谢谢。
