nacos-dubbo-springboot整合

先啟動nacos服務

服務端程式碼：

• 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檔案配置：

 <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>
    </properties>

        </dependency>

        <!-- Dubbo Nacos registry dependency -->

            <artifactId>dubbo-registry-nacos</artifactId>

                </exclusion>
            </exclusions>
        </dependency>

    </dependencies>

• 啟動類:

@SpringBootApplication
@NacosPropertySource(dataId = "example", autoRefreshed = true)
public class NacosConfigApplication {

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

• 定義dubbo介面：

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);
}

• 註冊dubbo服務：

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";
    }
}

• 啟動服務端，登陸nacos控制檯，可以看到服務已經註冊：
  

客戶端程式碼：

• application.properties配置，pom檔案配置與服務端相同，
• 啟動類：

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

• 測試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);
    }
}

• 啟動客戶端，
  
• 介面測試 ：
  http://localhost:8082/consumer/test
• 結果：
  test001
  說明服務正常呼叫
