Spring-cloud-alibaba-nacos（注册中心）快速入门

1、引入依赖

            <dependency>
                <groupId>com.alibaba.cloud</groupId>
                <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
                <version>2.1.0.RELEASE</version>
            </dependency>

2、配置文件配置

spring:
  cloud:
    nacos:
      discovery:
        server-addr: 120.77.181.202:8848 #nacos地址
  application:
    name: coupon # 注册的服务名 必须加，否则不能注册

3、启动类加@EnableDiscoveryClient 开启服务的注册与发现

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