Question

我遇到了 Spring Cloud 的问题。使用的版本是，

Spring 启动版本：2.4.4 Spring Cloud 版本：2020.0.2

您的意见将帮助我解决微服务启动问题。

我有一个 Spring Cloud 配置服务器，它从存储库和端点中选择数据

http://localhost:8888/xyz-service/default 返回数据。

我正在尝试从无法连接到配置服务器的微服务读取配置，请参考以下错误

Answer 1

我看到那个人没有回答，我有两个不同的应用程序。它们具有相同的配置和相同的 POM，但其中一个给了我这个错误。这是两个应用程序的配置，都使用spring boot 2.4.4版本，使用java 11，spring cloud 2020.0.2

spring.cloud.config.enabled=false
spring.jmx.enabled=true
management.endpoints.web.exposure.include=*

但第二个失败，错误与上面类似 java.lang.IllegalStateException: 无法从 'optional:configserver:' 加载配置数据

java.lang.IllegalStateException：无法从“http://localhost:8888”加载配置数据
