我遇到了一个关于Spring Cloud的问题。使用的版本是，

** Spring Boot 型：2.4.4Spring Cloud版：2020年0月2日**

您的输入将帮助我解决微服务启动问题。
我有一个spring cloud config服务器，它从存储库和端点中提取数据
返回数据。
我正在尝试从微服务读取配置，该微服务无法连接到配置服务器，请参阅以下错误

我看到那个人没有回答，我有两个不同的应用程序。它们有相同的配置和相同的POM，但其中一个给我这个错误。这是两个应用程序的配置，都使用Sping Boot 版本2.4.4，使用Java 11，Spring Cloud 2020.0.2

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

但是第二个函数失败，并显示与上述java.lang.IllegalStateException类似的错误：无法从“optional：configserver：”加载配置数据

确保在pom.xml中具有以下依赖项：

<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-config</artifactId>
    </dependency>

这个问题的主要原因是spring Boot 不知道如何从（比如）github上的repository中读取配置，要解决这个问题，你应该检查一下对应的模块中是否存在以下依赖（版本可以不同）：

implementation 'org.springframework.cloud:spring-cloud-starter-config:3.1.5'

连接此启动器应该可以解决您的问题

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