我正在尝试使用以下属性运行我的 Spring 启动应用程序，我希望它会继续重试从配置服务器加载属性 50 次，在任何两次尝试之间等待 6 秒，即使在它无法连接到配置服务器之后，它应该恢复启动或退出（我对重试后 Spring 启动能够执行的任何操作都无动于衷）。但它的行为似乎不像预期的那样。
我的启动命令 -
java -jar -Dspring.application.name=maas-gateway -Dspring.cloud.config.uri=http://localhost:8888 -Dspring.cloud.config.failFast=false -Dspring.cloud.config.retry.initialInterval=5000 -Dspring.cloud.config.retry.maxInterval=7000 -Dspring.cloud.config.retry.maxAttempts=50 maas-gateway-1.0-SNAPSHOT.jar
但是我遇到以下错误，因为它在一次尝试后恢复启动。

描述：
无法确定数据库类型无的嵌入式数据库驱动程序类
操作：
如果你想要一个嵌入式数据库，请在类路径上放一个受支持的数据库。如果要从特定配置文件加载数据库设置，则可能需要激活它（当前没有配置文件处于活动状态）。
添加spring-retry作为依赖项。
