我有一个具有以下配置的非常简单的客户端。 bootstrap.yml ：
static allowedMethods = [show: 'GET', update: 'POST']
我的Spring Boot应用程序如下：
spring:
application:
name: microservice-expedition
cloud:
config:
uri: http://localhost:9101
我正在使用Spring Cloud，并且为此服务推送了此配置。 microservice-expedition.properties ：
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);
}
}
我还有其他客户端可以在相同的配置下正常工作，但是这个客户端不能使用，我也不明白为什么。我总是收到以下错误：
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/
我的服务器配置的配置文件是：
2018-09-03 11:01:02.074 INFO 2784 --- [ main] c.c.c.ConfigServicePropertySourceLocator : Fetching config from server at: http://localhost:9101

我已经在论坛中搜索了几个小时，而我却感到绝望...
有人对此有想法吗？
感谢前进
PS：抱歉，我的英语不是很好...
