            kryo-serializers
            0.45
        
    

6. 创建接口DubboDemo

 

package com.sunrd.service;

public interface DubboDemo {
    /**
     * 测试接口
     * @return
     */
    String sayHello();
}

7. dubbo-provider引入dubbo-client

    
        com.sunrd
        dubbo-client
        1.0-SNAPSHOT
    

8. 创建DubboDemo的实现类DubboDemoImpl

package com.sunrd.service.impl;

import com.sunrd.service.DubboDemo;

/**
 * @author sunrd
 * @description
 * @date 2020/7/28
 */
public class DubboDemoImpl implements DubboDemo {
    @Override
    public String sayHello() {
        return "hello, dubbo";
    }
}

9. 在实现类上添加注解@DubboService

@DubboService(interfaceClass = DubboDemo.class)
public class DubboDemoImpl implements DubboDemo {
    @Override
    public String sayHello() {
        return "hello, dubbo";
    }
}

10. 在resources中创建配置文件application.yml

spring:
  application:
    name: DUBBO-PROVIDER
dubbo:
  protocol:
    name: dubbo
    serialization: kryo
    port: 20980
  registry:
    address: nacos://192.168.5.3:8848 # 自己的nacos地址
    check: false
    group: noncore
    version: 1.0
    protocol: nacos
    parameters:
      namespace: dev
  provider:
    version: 1.0
    group: noncore

11. 创建启动类

package com.sunrd.service;

import org.apache.dubbo.config.spring.context.annotation.DubboComponentScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * @author sunrd
 * @description
 * @date 2020/7/28
 */
@SpringBootApplication
// dubbo服务扫描的包
@DubboComponentScan(basePackages = {
    "com.sunrd.service.impl"
})
public class ProviderApplication {
    public static void main(String[] args) {
        SpringApplication.run(ProviderApplication.class, args);
    }
}

12. 创建消费者工程dubbo-consumer

13. 引入pom坐标

    
        springboot-dubbo
        com.sunrd
        1.0-SNAPSHOT
    
    4.0.0

    dubbo-consumer

    
        
            com.sunrd
            dubbo-client
            1.0-SNAPSHOT
        
        
            org.springframework.boot
            spring-boot-starter-web
        
    

14. 在resources下创建application.yml

spring:
  application:
    name: DUBBO-CONCUMER
dubbo:
  protocol:
    name: dubbo
    serialization: kryo
    port: 20980
  registry:
    address: nacos://42.194.181.247:8848 # 自己的nacos地址
    check: false
    group: noncore
    version: 1.0
    protocol: nacos
    parameters:
      namespace: dev
  consumer:
    group: noncore
    check: false
    version: 1.0

15. 创建controller进行消费

package com.sunrd.controller;

import com.sunrd.service.DubboDemo;
import org.apache.dubbo.config.annotation.DubboReference;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author sunrd
 * @description
 * @date 2020/7/28
 */
@RestController
public class DubboTestController {
    @DubboReference
    private DubboDemo dubboDemo;

    @RequestMapping("/hello")
    public String sayHello(){
        return dubboDemo.sayHello();
    }
}

16. 创建启动类ConsumerApplication

package com.sunrd.controller;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * @author sunrd
 * @description
 * @date 2020/7/28
 */
@SpringBootApplication
public class ConsumerApplication {
    public static void main(String[] args) {
        SpringApplication.run(ConsumerApplication.class, args);
    }
}

17. 启动dubbo-provider和dubbo-consumer，查看nacos

18. 测试访问：localhost:8080/hello
