最近在spring cloud 部署的時候，發現之前可以從git/github/gitlab中獲取資料庫資訊，但是現在不可以，可有的服務又可以，發現可以從git/github/gitlab中獲取資料庫資訊的微服務，在啟動的時候，列印Spring boot圖示的下面，會打印出從git獲取配置資訊的如下：

但是有的微服務就不能打印出上面的資訊，尋找其中的區別，發現pom.xml檔案中必須引入：spring-cloud-starter-config

    <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-config</artifactId>
        </dependency>

這樣就可以獲取資料庫配置資訊了！

具體如何配置資訊，請參考文章：
