### 1，安装nacos ###

**从 Github 上下载源码方式**

git clone https://github.com/alibaba/nacos.git
    cd nacos/
    mvn -Prelease-nacos -Dmaven.test.skip=true clean install -U  
    ls -al distribution/target/
    
    // change the $version to your actual path
    cd distribution/target/nacos-server-$version/nacos/bin

**下载编译后压缩包方式**  
下载地址：https://github.com/alibaba/nacos/releases

unzip nacos-server-$version.zip 或者 tar -xvf nacos-server-$version.tar.gz
      cd nacos/bin

**启动服务器**  
Linux/Unix/Mac  
启动命令(standalone代表着单机模式运行，非集群模式):

sh startup.sh -m standalone

如果您使用的是ubuntu系统，或者运行脚本报错提示\[\[符号找不到，可尝试如下运行：

bash startup.sh -m standalone

Windows  
启动命令：

cmd startup.cmd

或者双击startup.cmd运行文件。

**nacos控制台界面**  
http://ip:port/nacos/index.html  
默认用户名：nacos  
默认密码：nacos

### 2，项目框架结构 ###

*  api：接口部分，对外提供接口使用
 *  provider：服务的提供者
 *  consumer：服务的消费者

### 3，springboot整合dubbo ###

**1，父工程pom**

        <groupId>person.david</groupId>
        <artifactId>springboot-nacos-dubbo</artifactId>
        <packaging>pom</packaging>
        <version>1.0</version>
        <modules>
            <module>provider</module>
            <module>consumer</module>
            <module>api</module>
        </modules>
    
        <parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-parent</artifactId>
            <version>2.2.2.RELEASE</version>
        </parent>
    
    </project>

**2，api模块**  
TestApi.class

/**
     * @author David
     * @className TestApi
     * @date 2020/4/7 16:47
     */
    public interface TestApi {
        
    
        String sayHello(String name);
    }

**3，provider提供者模块**

SayHelloProvider.class

import org.apache.dubbo.config.annotation.Service;
    import person.david.api.TestApi;
    
    /**
     * @author Administrator
     * @create 2020/4/7
     * @since 1.0.0
     */
    @Service
    public class SayHelloProvider implements TestApi {
        
    
        @Override
        public String sayHello(String name) {
        
            return "收到提供者返回的消息========>Hello,"+name;
        }
    }

ProviderStart.class

import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    /**
     * @author Administrator
     * @create 2020/4/7
     * @since 1.0.0
     */
    @SpringBootApplication
    public class ProviderStart {
        
    
        public static void main(String[] args) {
        
            SpringApplication.run(ProviderStart.class, args);
        }
    }

application.yml

spring:
      application:
        name: nacos-provider
    dubbo:
      scan:
        base-packages: person.david.provider
      protocol:
        name: dubbo
        port: 12345
      registry:
        address: nacos://120.75.70.231:8848
    server:
      port: 10000

**4，consumer消费者模块**  
SayHelloController.class

import org.apache.dubbo.config.annotation.Reference;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    import person.david.api.TestApi;
    
    /**
     * @author Administrator
     * @create 2020/4/7
     * @since 1.0.0
     */
    @RestController
    @RequestMapping("/nacos")
    public class SayHelloController {
        
    
        @Reference
        private TestApi testApi;
    
        @RequestMapping("/sayHello")
        public String SayHello(){
        
    
            return testApi.sayHello("nacos");
        }
    }

ConsumerStart.class

import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    /**
     * @author Administrator
     * @create 2020/4/7
     * @since 1.0.0
     */
    @SpringBootApplication
    public class ConsumerStart {
        
    
        public static void main(String[] args) {
        
            SpringApplication.run(ConsumerStart.class, args);
        }
    }

application.yml

spring:
      application:
        name: nacos-consumer
    dubbo:
      registry:
        address: nacos://120.75.70.231:8848
        username: nacos
        password: nacos
    server:
      port: 10001

### 4，启动提供者，消费者服务 ###
