• 創(chuàng)建 application.yml文件（main - resources文件夾下），ip改改就好了

## 服務端口
server:
  port: 8002

## spring
spring:
  application:
    ## 服務名稱
    name: service01
  cloud:
    nacos:
      discovery:
        ## nacos ip
        server-addr: localhost:8848
  datasource:
    url: jdbc:mysql://127.0.0.1:3306/excel_demo?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT

    password: password
  # redis配置

    # 鏈接超時時間
    timeout: 5000
    jedis:

        min-idle: 0

• 創(chuàng)建服務啟動類

package com.wyh;

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

@SpringBootApplication
@EnableDiscoveryClient
public class Services01 {
    public static void main(String[] args) {
        SpringApplication.run(Services01.class, args);
    }

}

3、驗證

啟動 service01 服務（如果啟動失敗，報JDK沒有設置等錯誤，項目close掉，刪除父項目下的idea文件夾，然后選擇父pom重新導入一下分布式項目就ok，筆者使用2020版本的idea，這個版本自動遞歸導入子項目，之前的版本可以勾選遞歸導入）
