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
