我正在尝试将我的 AstraDatabase (Cassandra) 与我的 Spring Boot 应用程序连接起来。我已经完成了运行它时所需的所有配置。它向我显示异常：创建名称为“org.springframework.boot.autoconfigure.data.cassandra.CassandraDataAutoConfiguration”的bean时出错：通过构造函数参数0表达的依赖关系不满足。 它显示 “config.json” 文件丢失，尽管它作为绝对位置存在于资源中的 secure-bundle.zip 中。

您是否在 cassandra 中创建了 keyspace ，如果您的 keypsace =main 未创建，您将收到此错误。
请找到工作示例
这也让我很困扰，但是当我给它一个 ZIP 文件本身而不是解压缩的文件夹的引用时，它工作得很好。
