Spring Cloud - 客户端在 Spring boot 2.5.6 中不使用 spring.config.import 从配置文件服务器获取配置

Question

我完全陷入了配置客户端无法从配置文件服务器获取配置的问题。我正在尝试使用 spring.config.import 通过“新方式”来做到这一点，但看起来我错过了一些东西。

我将属性文件存储在私有 github 存储库中。这是我的配置文件服务器：application.properties：

spring.application.name=config-server
server.port=8888
spring.cloud.config.server.git.uri=https://github.com/Pavello/simple-microservices-app-config-files-repo
spring.cloud.config.server.git.username=//My username
spring.cloud.config.server.git.password=//Here I am using my private token
spring.cloud.config.server.git.default-label=master

management.endpoints.web.exposure.include=busrefresh

spring.rabbitmq.host=localhost
spring.rabbitmq.user=guest
spring.rabbitmq.password=guest
spring.rabbitmq.port=5672

pom.xml：

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

            <version>3.0.4.RELEASE</version>
        </dependency>

我的客户端应用程序如下所示：application.properties：

server.port=${PORT:0}
spring.application.name=user-service
eureka.client.serviceUrl.defaultZone=http://localhost:8010/eureka
eureka.instance.prefer-ip-address=true
eureka.instance.instance-id=${spring.application.name}:${spring.application.instance_id:${random.value}}
spring.h2.console.enabled=true
spring.h2.console.settings.web-allow-others=true

spring.config.import=optional:configserver:http://localhost:8888
management.endpoints.web.exposure.include=*

运行我的配置文件服务器后，我在 /user-service/default 下收到以下响应：

{
"name": "user-service",
"profiles": [
"default"
],
"label": null,
"version": "889d16cb37b5467ed4546d617fc5ba8280c96f2d",

"spring.datasource.username": "postgres",
"spring.datasource.password": "postgres",
"spring.datasource.initialization-mode": "always"
}
},
{
"name": "https://github.com/Pavello/simple-microservices-app-config-files-repo/file:C:\\Users\\PAWEL~1.KAN\\AppData\\Local\\Temp\\config-repo-15000982762999853489\\application.properties",

"spring.datasource.username": "postgres",
"spring.datasource.password": "postgres",
"spring.datasource.initialization-mode": "always"
}
}
]
}

所以看起来它正在正确获取配置，但在客户端我没有这些值，并且收到此错误：

我读过一些与 Spring Boot 和 Spring Cloud 版本不匹配相关的类似问题，但我想我正在使用 Spring Boot (2.5.6) 和 Spring Cloud (2020.0.4) 的最新（目前）版本）。我尝试将 spring cloud bootstrap 依赖项添加到我的用户服务中（尽管我认为没有必要）（就像建议的其他一些问题一样）：

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-bootstrap</artifactId>
    <version>3.0.4</version>
</dependency>

但这也没有帮助。有人可以帮忙吗？
