我已经使用 spring cloud Netflix OSS 部署了几个 Spring boot 应用程序，并配置了 Spring boot Admin 来监控那些连接到 Eureka 服务器的应用程序。但是对于其中两个应用程序，我遇到了错误。您能否让我知道导致此错误的原因以及如何缓解此错误。

此端点健康 URL 由 Spring 引导执行器提供，并且健康 URL 的输出是{"description":"Spring Cloud Eureka Discovery Client","status":"UP"}

日志中的错误

URL 末尾有一个额外的空格

eureka.instance.healthCheckUrlPath=${management.context-path}/health

它应该是

eureka.instance.healthCheckUrlPath=${management.context-path}/health
