我正在尝试将我的spring启动应用程序“config test”连接到springframework的云配置服务器。它没有选择应用程序的配置,而是回答一个错误并中止应用程序(因为fail fast选项):
Could not extract response: no suitable HttpMessageConverter found for response type [class org.springframework.cloud.config.environment.Environment] and content type [text/html;charset=UTF-8]
连接到配置服务器时显示:

我已经在bootstrap.yml属性文件中定义了云配置服务器的uri。bootstrap.yml是:
spring:
cloud:
config:
name: config-test
uri: http://localhost:8081
fail-fast: true
logging:
level:
com.harry.potter.logging_test: trace
我有一个“application.properties”文件,可以在运行时启用配置客户端的/refresh功能:
management.endpoints.web.exposure.include=*

当通过请求(使用curl)激活时,config服务器按预期工作,将本地文件的配置内容组织为git存储库。
我做错什么了?

这里的问题是,配置客户机请求配置服务器时没有凭据(或者凭据错误)。
在本例中,spring的configservicepropertysourcelocator抛出上述异常,并显示一条相当误导性的消息:
关于凭证和云配置服务器,baeldung教程“springcloud简介”说:
我们还需要为application.properties中的基本身份验证设置用户名和密码,以避免每次重新启动应用程序时自动生成密码。
每次配置客户端向服务器查询配置时,都需要这些凭据。我已将凭据添加到“bootstrap.yml”属性文件:
成功了。
