健康检查时Spring Boot Admin非法字符

Question

我使用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。但对于其中两个应用程序，我得到了以下错误。你能告诉我这个错误的原因是什么，以及如何缓解这个问题吗。

这个endpoint健康URL由Spring boot actuator提供，健康URL的输出是{“description”：“Spring Cloud Eureka Discovery Client”，“status”：“UP”}

日志中的错误

Answer 1

在URL的末尾有一个额外的空格

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

应该是的

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