我正在尝试使用 Heroku 运行 spring-cloud hello world。我正在尝试使用工头，我得到以下堆栈跟踪：

我错过了一个“工头”连接器吗？

好的，我将解释为什么我的问题是荒谬的以及如何“解决它”。

首先， spring-cloud-connectors项目中有一个localconfig-connector 。因此，您可以使用 Main 类 yadiyadiyada 以“旧方式”启动您的 Spring 应用程序。

然而，它只是部分地解决了问题，因为工头仍然应该被用来在本地启动应用程序，“就像 Heroku 一样”。但是，您将需要一个不同的 Procfile 或不同的 .env 文件来设置 JAVA_OPTS 并按照 localconfig-connector 的要求使用 -Dspring.cloud.appId=myappname ，如下所示：

JAVA_OPTS=$JAVA_OPTS -Dspring.cloud.appId=myappname
