停止Spring Boot应用程序的启动，直到spring cloud config server启动

Question

我试图运行我的spring boot应用程序，设置了以下属性，我希望它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，即使在此之后，它不能连接到配置服务器，它应该恢复启动或退出（我对重试后spring boot能够做的事情无所谓）。但它似乎并不像预期的那样表现。

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

如果您想要一个嵌入式数据库，请在类路径上放置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。
