netflix-eureka - DiscoveryClient 无法刷新其缓存!状态 404

Question

我已经设置了 Intershop Commerce Management 7.8 并且一切正常，除了我在错误日志文件中不断出现错误。

Eureka 正在运行，我可以使用 http://localhost:8760 访问 Eureka UI
应用程序服务器和 Solr 已列出并正在运行。

eureka-client.properties 中的 URL 设置为:
http://localhost:8760/eureka

任何想法这里有什么问题？

这里有一些错误条目:

Answer 1

这个问题有一个简单的解决方案。 eureka 客户端只是有点挑剔:
使用' http://localhost:8760/eureka/ ' 而不是 ' http://localhost:8760/eureka '。
我希望这有帮助。
