SpringCloudAlibaba 2021.0.4.0—nacos配置作為服務中心的配置

這裡的SpringCloudAlibaba的版本2021.0.4.0、SpringCloud版本2021.0.5、SpringBoot版本2.6.13,nacos服務端版本2.1.2，一定要做好版本控制，否則服務啟動會出一堆莫名奇妙的錯誤

需要用到的依賴:

<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
</dependency>           

在項目中建立bootstrap.yml作為服務的啟動引導配置，然後在nacos中添加應用的配置

bootstrap.yml的内容：

spring:
  application:
    name: cloud-gateway
  cloud:
    nacos:
      config:
        server-addr: http://192.168.137.18:8848
        file-extension: yaml
  profiles: #多環境配置
    active: dev           

nacos中的應用配置

啟動服務異常：
