先[启动nacos服务][nacos]

###### 服务端代码： ######

*  application.properties配置：

nacos.config.server-addr=127.0.0.1:8848
    
     endpoint http://localhost:8080/actuator/nacos-config
     health http://localhost:8080/actuator/health
    management.endpoints.web.exposure.include=*
    management.endpoint.health.show-details=always
    
    ##dubbo config
    spring.application.name=test
    dubbo.registry.address=nacos://127.0.0.1:8848
    dubbo.application.name=spring-boot-nacos
    dubbo.scan.basePackages=com.alibaba.nacos.example.spring.boot.service
    dubbo.protocol.name=dubbo
    dubbo.protocol.port=-1

*  pom文件配置：

<properties>
            <spring-boot.version>2.0.3.RELEASE</spring-boot.version>
            <nacos-config-spring-boot.version>0.2.1</nacos-config-spring-boot.version>
            <netty-all.version>4.0.35.Final</netty-all.version>

                    <exclusion>
                    <groupId>com.alibaba</groupId>
                    <artifactId>dubbo</artifactId>

                </exclusions>
            </dependency>
    
        </dependencies>

*  启动类:

@SpringBootApplication
    @NacosPropertySource(dataId = "example", autoRefreshed = true)
    public class NacosConfigApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(NacosConfigApplication.class, args);
        }
    }

*  定义dubbo接口：

package com.alibaba.nacos.interfaces;
    
    /**
     * @author yanming
     * @version 1.0.0
     * @description
     * @date 2019/02/20 18:51
     **/
    public interface ITestNacos {
        String getOrderFormat(Integer integer);
    }

*  注册dubbo服务：

import com.alibaba.dubbo.config.annotation.Service;
    import com.alibaba.nacos.interfaces.ITestNacos;
    
    @Service(group = "test-nacos2", retries = 0, timeout = 10000)
    public class TestNacosService implements ITestNacos {
    
        @Override
        public String getOrderFormat(Integer integer) {
           return "test001";
        }
    }

*  启动服务端，登陆nacos控制台，可以看到服务已经注册：

###### 客户端代码： ######

*  application.properties配置，pom文件配置与服务端相同，
 *  启动类：

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

*  测试demo:

import com.alibaba.dubbo.config.annotation.Reference;
    import com.alibaba.nacos.interfaces.ITestNacos;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    /**
     * @author yanming
     * @version 1.0.0
     * @description
     * @date 2019/02/21 9:46
     **/
    @Controller
    @RequestMapping("consumer")
    public class TestNacosConsumer {
    
        @Reference(group = "test-nacos2")
        ITestNacos iTestNacos;
    
        @RequestMapping(value = "test",method = RequestMethod.GET)
        @ResponseBody
        public String getCounsumerTest(){
            return iTestNacos.getOrderFormat(1);
        }
    }

*  启动客户端，  
    ![在这里插入图片描述][20190221160539653.png]
 *  接口测试 ：  
    [http://localhost:8082/consumer/test][http_localhost_8082_consumer_test]
 *  结果：  
    test001  
    说明服务正常调用
