首先是去nacos官網下載最新的包：Nacos 快速開始 | Nacos

win下啟動命令：startup.cmd -m standalone

這樣就可以訪問你的nacos 了。

添加一個配置，記住你的 DataId,和Group名字。

創建一個pom項目，引入springCloud

更新依賴后，創建一個子模塊。一般就是springboot項目

這里可以看下是否可以跑起來。正常你配個web,和數據庫地址就應該可以起來。并可以正常訪問你的控制器接口。

然后復制這個配置到nacos那個配置。

修改本地配置指向nacos

server:port: 8001
spring:application:# 服務名稱name: bms-cloudprofiles:active: devcloud:nacos:#discovery 服務注冊discovery:server-addr: 192.168.1.166:8848#分組group: DEFAULT_GROUP# 注冊到nacos上的服務名稱，默認{${spring.application.name}service: ${spring.application.name}#config 讀取nacos上的服務配置config:file-extension: yaml#分組group: DEFAULT_GROUPserver-addr: 192.168.1.166:8848

再次啟動就可以看到可以從nacos上獲取配置文件了。
