我正试图将Travis CI用于我的春季启动api，但在尝试构建时遇到了以下错误。

执行时不会出现错误/mvnw-test-B本地。
如果需要，我可以发布完整的日志文件。
我是构建Spring应用程序的新手，所以如果有明显的问题，请原谅我！
原因是Spring无法连接到地址为bodify-shard-00-01-o8kg0.mongodb.net:27017的远程MongoDB实例，并且在30秒后超时。
MongoDB管理系统允许连接到本地计算机的IP地址进行开发，这就是为什么可以建立连接的原因。
然而，Travis CI在不同的IP地址和服务器上运行，因此您必须根据远程集群(或实例(的MongoDB管理系统中的操作系统明确允许其IP地址。
以下是相关的Travis CI文档：IP地址。还有一种说法是：
Travis CI使用的构建机器的IP地址在您需要将其安全列出以访问内部资源时会很有帮助。由于构建在各种不同的基础设施中运行，因此安全列表的IP范围取决于构建运行的基础设施。
将MongoDB的IP地址列入白名单的方法，您需要遵循提供商的说明。
