快速搭建

1. 构建工具地址:http://start.aliyun.com
   
2. 选最基本依赖
   

代码

1. 把IDEA自动生成的代码删除，只留下启动类,我把修改bootstrap.properties文件格式改成了bootstrap.yml，代码修改如下:

spring:
  application:
    name: demo-dubbo-service
  cloud:
    nacos:
      server-addr: localhost:8848
      config:
        file-extension: yml

2. 添加nacos配置，spring.application.name和file-extension两个属性跟nacos配置中心的写法是有关的。nacos配置的data Id就是 spring.application.name+file-extension作为后缀
   
3. 启动类打印，可以成功获取到test.t1这个配置

package com.lwb.demo.dubbo;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

import javax.annotation.PostConstruct;

@SpringBootApplication
public class DemoDubboApplication {
    
    

    @Value("${test.t1}")
    String value;

    @PostConstruct
    public void init() {
    
    
        System.out.println(value);
    }

    public static void main(String[] args) {
    
    
        SpringApplication.run(DemoDubboApplication.class, args);
    }

}
