## 报错原因 ##

*  项目中的eureka注册配置无效 (http://localhost:8700/eureka)
 *  默认选择使用了springcloud 默认的注册中心地址 (http://localhost:8761/eureka)

### 项目中的配置
    
    spring:
      application:
        name: order-api
    # 配置端口
    server:
      port: 8800
    
    # 指定当前eureka客户端的注册地址，也就是eureka服务的提供方，当前配置的服务的注册服务方
    eureka:
      instance:
        hostname: localhost
      client:
        service-url:
          defaultZone: http://localhost:8700/eureka/ ## 项目启动时没有读取到此相关配置

## 解决方案 ##

### 1、配置有问题 ###

请仔细检查 eureka 的配置是否有误

### 2、没有读取到相关配置文件 ###

请检查配置文件 application.yml , application.properties 是否命名正确, 是否位置正确

> ## 本人错误原因 : ##
> 
> application.yml 配置无误, 但是系统没有读取这个配置文件 .  
> 原因 : idea maven 项目 , resouces 目录为普通文件夹  
> 解决方案 :  
> 选择 resouces 文件夹 , 右键 Mark Directory as \[ Resouce Root \] 即可解决
