# 1.首先搭建nacos #

参考文章 : [docker 安装 nacos 1.X][docker _ nacos 1.X]

# 2.项目结构 #

*  使用依赖
 *  springboot 2.2.2.RELEASE
 *  springcloud Hoxton.RELEASE
 *  springcloud alibaba 2.1.1.RELEASE

# 3.父工程创建 #

# 4.创建服务端子工程 alibaba-nacos-discovery-server #

pom.xml  工程文件

                <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
            </dependency>
        </dependencies>

application.yml   配置文件

spring:
      application:
        # 应用名称
        name: alibaba-nacos-discovery-server
      cloud:
        nacos:
          discovery:
            # nacos注册中心地址
            server-addr: 192.168.1.141:8848
    server:
      port: 8001

TestApplication.java  启动类

@EnableDiscoveryClient //启动注册中心客户端 注册到nacos
    @SpringBootApplication
    public class TestApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(TestApplication.class, args);
        }
    
    }

TestController.java  测试类(供客户端调用的接口编写)

@Slf4j
    @RestController
    public class TestController {
    
        @GetMapping("/test")
        public String hello(@RequestParam String name) {
            log.info("调用 name => " + name);
            return "参数 => " + name;
        }
    
    }

启动server端后查看nacos服务列表是否注册成功

nacos服务列表  服务名与我们设置的一致  表示注册成功

接下来调用服务端暴露的业务接口

返回值正确  nacos服务端完成
