Spring Boot, Eureka и Microservice: невозможно выполнить запрос на любом известном сервере

0 голосов
/ 03 сентября 2018

У меня очень простой клиент со следующей конфигурацией. bootstrap.yml : 

spring:
  application:
    name: microservice-expedition
 cloud:
    config:
      uri: http://localhost:9101

Приложение My Spring Boot выглядит следующим образом: 

package com.mexpedition;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@SpringBootApplication
@EnableDiscoveryClient
public class MexpeditionApplication {

    public static void main(String[] args) {
        SpringApplication.run(MexpeditionApplication.class, args);
    }
}

Я использую Spring Cloud и перенес эту конфигурацию для этой службы. microservice-expedition.properties : 

server.port:9003

#Configurations H2
spring.jpa.show-sql=true
spring.h2.console.enabled=true

#définit l'encodage pour data.sql
spring.datasource.sql-script-encoding=UTF-8

#Eureka
eureka.client.serviceUrl.defaultZone: http://localhost:9102/eureka/

У меня есть другие клиенты, которые отлично работают с той же конфигурацией, но этого нет, и я не понимаю, почему. Я всегда получал следующую ошибку: 

2018-09-03 11:01:02.074  INFO 2784 --- [           main] c.c.c.ConfigServicePropertySourceLocator : Fetching config from server at: http://localhost:9101

Файл конфигурации для моей конфигурации сервера: 

spring.application.name=config-server
server.port:9101

spring.cloud.config.server.git.uri=https://github.com/AmarMicroDev/mcommerce-config-repo.git

Я искал в форумах часы и часы, и я дезертирую ...

У кого-нибудь есть идеи по этому поводу?

Спасибо за аванс
