provider的application.yml配置文件

server:
  port: 9000

spring:
  application:
    name: *-provider

dubbo:
  application:
    name: dubbo-*-provider
  protocol:
    name: dubbo
    port: 20880
  registry:
    protocol: zookeeper
    address: 127.0.0.1:2181
    timeout: 20000
    file: ./dubbo-provider-*
  version: 1.0.0
  scan:
    base-packages:
      - com.milky.provider
  enable-file-cache: false

consumer的application.yml配置文件

server:
  port: 8088

spring:
  application:
    name: *-webadmin

dubbo:
  application:
    name: dubbo-consumer-webadmin
    enable-file-cache: false
  registry:
    protocol: zookeeper
    address: 127.0.0.1:2181
    timeout: 60000
    file: ./dubbo-consumer-webadmin
  version: 1.0.0
  scan:
    base-packages:
      - com.milky.webadmin

provider的启动类

package com.milky.provider;

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

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

consumer的启动类

package com.milky.webadmin;

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

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

一些注意事项

启动类需要加@EnableDubbo
服务实现类需要加@DubboService，指定向注册中心暴露该类，消费者可以调用其中的方法
订阅service要用到@DubboReference注入api模块的接口
