SpringBoot使用Nacos作为配置中心服务

spring cloud alibaba教程：如何使用nacos作为配置中心

startup.cmd -m standalone

1.下载与解压Nacos压缩包（Nacos安装指南具体教程可查看）
下载地址：https://github.com/alibaba/nacos/tags

2. 在bin目录下进入cmd，输入

startup.cmd -m standalone

即可

3.启动成功，访问测试（默认端口8848，用户名：nacos，密码：nacos）

4.新建一个springboot项目

5.修改pom.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

            </dependency>
        </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>

            </plugin>
        </plugins>
    </build>

</project>

6. 新建bootstrap.yml
   
   bootstrap.yml

spring:
  application:
    name: demo
  cloud:
    nacos:
      config:
        server-addr: 127.0.0.1:8848
        file-extension: yaml
        prefix: demo1
        namespace: 1f5f553b-33d1-4628-99e0-d46c45aaa455
        username: nacos
        password: nacos

#  profiles:
#    active: dev

7.运行，成功，已使用了Nacos配置文件demo1的属性

8.新建controller，输出属性字段

package com.example.demo.controller;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @program: demo
 * @author: daPangDong
 * @create: 2022-04-11 17:01
 */

@RestController
public class testController {

    @Value("${name}")
    private String number;

    @GetMapping("/getNumber")
    public String getNumber(){
        return number;
    }


}

9.成功
