Spring Cloud Config-Client cannot get the attribute value of the Config-Server configuration file on github

1. Project environment

 SpringBoot 2.1.7.RELEASE and SpringCloud Greenwich.SR2 are used in the project:

     <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.7.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>


    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Greenwich.SR2</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

2.Config-Server first ensure that it is started normally, and check whether the configuration file on github is correct;

For example: if the configuration content format is incorrect, access here will report an error;

3. Question:

      config-client has been unable to obtain the attribute value of the config-server configuration file on github;

(1). Bootstrap configuration read priority over application

    General application.yml /application.properties Modified bootstrap.yml /bootstrap.properties

(2) Configuration file format on github: (Note: It is easy to encounter pits)

 /{application}/{profile}[/{label}]：

  1： /{application}-{profile}.yml
  2： /{label}/{application}-{profile}.yml
  3： /{application}-{profile}.properties
  4： /{label}/{application}-{profile}.properties

(3) The wrong configuration file I just started:

Error one:

1: config-client 中 的 bootstrap.yml ：

spring:
  cloud:
    config:
      uri: http://localhost:8765
      profile: dev

2:github:

ps: At first I thought that as long as the  following dev is consistent with spring.cloud.config.profile = dev, it turns out that it is not possible;

Error two:

1: config-client 中 的 bootstrap.yml ：

spring:
  cloud:
    config:
      uri: http://localhost:8765
      profile: dev

At first, I thought that the following service name configuration was placed on github, and then read it with config-client, so I just changed the configuration file name format on github to the following, and found that it was still not possible

spring:
  application:
    name: morning-service-order

github: The configuration file is modified as follows: (Attach: yml online to properties )

correct:

My approach is to configure the service name in bootstrap.yml and name the configuration file in github:

Or yml format:
