Spring Cloud Config Server - array vazio para chaves atualizadas

Question

Eu tenho um servidor de configuração do Spring Cloud como neste repo E um cliente neste repo a seguir é meu arquivo POM

application.yml do servidor de configuração

server:
  port: 8081
spring:
  application:
    name: cloud-config-server
  cloud:
    config:
      server:
        monitor:
          github:
            enabled: true
          gitee:
            enabled: true
        git:
          password: ${PASSWORD}
          username: ${USERNAME}
          uri: https://github.com/Ali-Wassouf/springcloudconfigrepo
          search-paths: '{application}'

O repo de configuração que este servidor atende tem a seguinte estrutura

.
+-- serviceA
|   +-- application-dev.properties
|   +-- application-prod.properties
+-- serviceB
|   +-- application-dev.properties
|   +-- application-prod.properties

Eu tenho um webhook configurado para o repo de configuração. Eu também tenho uma imagem rabbitMQ rodando localmente.

Quando envio minhas alterações para o repositório de configuração, recebo essas linhas no console

o.s.c.c.monitor.PropertyPathEndpoint     : Refresh for: *:prod
s.c.a.AnnotationConfigApplicationContext : Refreshing org.springframework.context.annotation.AnnotationConfigApplicationContext@2c943d8f: startup date [Mon Nov 23 18:55:19 CET 2020]; root of context hierarchy

o.s.cloud.bus.event.RefreshListener      : Received remote refresh request. Keys refreshed []

A matriz de chaves atualizadas está vazia. Tentei mudar para uma versão mais antiga do Spring Boot / Cloud, bem como uma versão mais recente, mas não funcionou.

Eu vi perguntas semelhantes ao meu caso, mas nenhum deles tinha qualquer resposta.

Answer 1

Em seu application.ymlvocê definiu a spring.cloud.config.server.git.search-pathschave de configuração. No entanto, olhando para este documento da documentação oficial do spring, a chave parece ter sido searchPaths(snakeCase, sem travessão). Portanto, acho que você application.ymldeve ser assim:

server:
  port: 8081
spring:
  application:
    name: cloud-config-server
  cloud:
    config:
      server:
        monitor:
          github:
            enabled: true
          gitee:
            enabled: true
        git:
          password: ${PASSWORD} username: ${USERNAME}
          uri: https://github.com/Ali-Wassouf/springcloudconfigrepo
          searchPaths: '{application}'

Answer 2

O problema estava no cliente, estava faltando a configuração do Spring Cloud, bem como o gerenciamento de dependência para o Spring Cloud, adicionando esta dependência ao código do cliente

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

e adicionando este gerenciamento de dependência também

<dependencyManagement>
       <dependencies>
           <dependency>
               <groupId>org.springframework.cloud</groupId>
               <artifactId>spring-cloud-dependencies</artifactId>
               <version>${spring-cloud.version}</version>
               <type>pom</type>
               <scope>import</scope>
           </dependency>
       </dependencies>
</dependencyManagement>

Resolvido o problema.
