一，我們需要引用的包（nacos需對應springboot的2.3.6.RELEASE這個版本）

    <dependency>
        <groupId>com.alibaba.cloud</groupId>
        <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
        <version>2.2.3.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>com.alibaba.cloud</groupId>
        <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        <version>2.2
 
.3.RELEASE</version>
    </dependency>

二，啟動類的配置

package com.nl;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@SpringBootApplication
@EnableDiscoveryClient
 
public class NacosApplication {
    public static void main(String[] args) {
        System.out.println("test");
        SpringApplication.run(NacosApplication.class, args);
    }
}

三，配置檔案（需注意的點，配置必須在bootstrap.yml這裡新增）

spring:
  profiles:
    active: dev
  application:
    name: test
  cloud:
    nacos:
      config:
        
 
namespace: dev
        file-extension: yaml
        server-addr: https://nacos.test.com
        username: nacos_devtest
        password: 123456
      discovery:
        namespace: dev
        server-addr: https://nacos.test.com
        username: nacos_devtest
        password: 123456

四，測試

import com.nl.NacosApplication;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest(classes = NacosApplication.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class NaocsTest {
    @Value("${test.name}")
    private String Name;

    @Test
    public void NacosTest() {
        System.out.println("Test" + Name);
    }
}
