问题描述
Spring Cloud 的应用原本正常运行，但是重新发布了一次应用后，发现使用 Service Bus 服务的应用都无法启动并报 BeanInstantiationException 异常

问题解析
因为 Spring Cloud 应用程序 pom.xml 文件中定义的依赖 spring-cloud-starter-azure-spring-cloud-client 与当前版本 Azure Spring Cloud 的依赖冲突，导致 Configuration Service 初始化失败，进而导致应用无法启动。移除该依赖( spring-cloud-starter-azure-spring-cloud-client )后, 应用启动成功。
