為 camunda 8 平台執行 spring 示例時出錯

Question

我是一個新手，試圖為 camunda 8 平台執行 spring 示例。 我使用這個 docker-compose文件在本地運行 camunda 8 平台。 附上本地 docker ps 命令的截圖。

克隆項目后，我將 application.local.properties 重命名為 application.properties，以便應用程序可以連接到本地 zeebe 集群（並且我刪除了包含雲屬性的現有 application.properties）但是當我執行 ProcessApplication 類時，我收到錯誤“org.springframework.context.ApplicationContextException：無法啟動 bean 'zeebeClientLifecycle'

下面是詳細的錯誤跟蹤。 我有點驚訝，一個開箱即用的例子沒有奏效。 有人可以指導我進一步解決這個問題嗎？

謝謝。

Answer 1

將 application.properties 文件重命名為 application.yaml 文件后問題得到解決。 應用程序成功啟動。 事實上，在應用程序啟動后，我可以從 yaml 恢復到屬性，它仍然可以工作。

奇怪的問題。
