SpringBoot整合Dubbo超简单 -provider

springBoot整合dubbo的好处是可以放弃xml配置，可以使用注解的方式配置dubbo

DubboStarter分两个版本，旧版的io.dubbo.springboot,还有基于Apache的org.apache.dubbo，这里是用的最新版Apache的DubboStarter

application.properties

dubbo.application.name=provider dubbo.registry.address=zookeeper://127.0.0.1:2181 dubbo.protocol.name=dubbo dubbo.protocol.port=20880

暴露的接口

package com.startup.service;

public interface ISayService {

    String sayHello();
}

package com.startup.service;

import org.apache.dubbo.config.annotation.DubboService;

@DubboService
public class SayServiceImpl implements ISayService {
    public String sayHello() {
        return "hello..........";
    }
}

直接启动就OK了，先启动Zookeeper

package com.startup;

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

import java.util.concurrent.CountDownLatch;

@SpringBootApplication
@EnableDubbo(scanBasePackages = {"com.startup.service"})
public class Application {

    public static void main(String[] args) throws InterruptedException {
        SpringApplication.run(Application.class,args);
        System.out.println("dubbo service started");
        new CountDownLatch(1).await();
    }
}
