Nacos（1.2）- nacos 服务注册

在注册服务前先保证 nacos-server 启动，控制台地址为：http://127.0.0.1:8848/nacos/index.html

未注册任何服务，此时服务列表栏为空。

①创建 springboot 工程 nacos_demo
定义相关依赖

<properties>
    <java.version>1.8</java.version>
     <spring-cloud.version>Finchley.RELEASE</spring-cloud.version>
 </properties>
<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
                <version>0.2.2.RELEASE</version>
            </dependency>
            <dependency>
                <groupId>com.alibaba.nacos</groupId>
                <artifactId>nacos-client</artifactId>
                <version>1.1.0</version>
            </dependency>
        </dependencies>
    </dependencyManagement>

② 创建子模块 nacos_demo_provider ，引入相关依赖

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        <exclusions>
            <exclusion>
                <groupId>com.alibaba.nacos</groupId>
                <artifactId>nacos-client</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>com.alibaba.nacos</groupId>
        <artifactId>nacos-client</artifactId>
    </dependency>
</dependencies>

③ 配置需要向nacos注册的服务，其中127.0.0.1:8848为nacos-server地址

server:
  port: 9091

spring:
  application:
    name: nacos-provider
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848

④ 编写启动类

package com.hs.nacos_demo.provider;

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

@SpringBootApplication
@EnableDiscoveryClient
public class NacosDemoProviderApplication {

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

}

⑤ 启动服务测试，如下 nacos 服务端已经监听到 nacos-provider 注册进来

同一个服务可以运行多个实例，如下：
