SpringCloud使用bootstrap配置Nacos的注册中心和配置中心

导入配置

 <dependencys>
    <dependency>
          <groupId>org.springframework.cloudgroupId>
          <artifactId>spring-cloud-starter-bootstrapartifactId>
      dependency>
 dependencys>

当使用对应的bootstrap进行配置的时候要注意对应的配置的优先级：bootstrap.yml>application.properties>application.yml>外部文件（多文件遵守properties>yml）

开始配置bootstrap.yml

server:
  port: 9090

spring:
  application:
    name: OFOGateway
  profiles:
    # 环境配置
    active: dev

  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848
        namespace: dev
      config:
        server-addr: 127.0.0.1:8848
        namespace: e9d6c1b0-75c6-4d3c-a099-58556a6a5edd
        file-extension: yml
        shared-configs:
          - application-all.${spring.cloud.nacos.config.file-extension}

这里会匹配Nacos的OFOGateway.yml、application-all.yml配置文件
