这个错误是由于在创建名为'newsController'的bean时出现了依赖问题。具体来说，'newsController'依赖于'newsService'，而'newsService'又依赖于'newsRepository'。错误消息中提到了在创建'newsRepository'时出现了问题。

根据错误信息，看起来是无法连接到Elasticsearch引起的问题。可能的原因是Elasticsearch服务没有启动或者连接配置有误。

请确保Elasticsearch服务已经正确启动，并且在Spring Boot应用程序的配置文件中正确配置了Elasticsearch连接信息。您可以检查连接URL、主机和端口等参数是否正确设置。

另外，请确保您的Spring Boot项目中已经引入了适当的Elasticsearch依赖项，并且版本与您正在使用的Elasticsearch服务器版本兼容。

如果问题仍然存在，请检查网络连接和防火墙设置，确保应用程序能够与Elasticsearch建立正常的连接。

希望这些信息能对您有所帮助，如果问题仍然存在，请提供更多的错误日志和代码细节，以便我们更好地帮助您解决问题。
