配置文件

dubbo:
  application:
    name: dubbo-provider
  registry:
    address: localhost:2181
    protocol: zookeeper
    check: false
  protocol:
    name: dubbo

实现类

package com.knife.DubboProviderTest;


import com.alibaba.dubbo.config.annotation.Service;
import com.knife.api.dubboService;

@Service
public class dubboServiceImpl implements dubboService {

	@Override
	public String helloDubbo() {
		// TODO Auto-generated method stub
		
		System.err.println("be called ...");
		
		return "hello dubbo";
	}

}

启动类

package com.knife.DubboProviderTest;

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

import com.alibaba.dubbo.config.spring.context.annotation.EnableDubbo;

@SpringBootApplication
@EnableDubbo
public class App {

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