最近写了一篇SpringCloud整合Dubbo的技术贴，本篇内容有点类似，Dubbo本身就是微服务框架，整合SpringBoot之后，可以吸收SpringBoot框架的自动装配功能；

Dubbo集成SpringBoot框架的目的，是为了实现Springcloud的标准，如果想在SpringCloud生态中集成阿里的组件，整合比较复杂，接下来，我们先介绍一下如何整合：

二、代码示例：

1、代码结构：

微服务框架-Dubbo整合SpringBoot框架-宝典

2、创建maven quickstart工程-springboot-dubbo-api ,编写服务端与客户端交互的接口契约，同时安装到Maven私有仓库。

package com.jason.dubbo.springboot;

/**
 * @program: springcloud-dubbo
 * @description
 * @author: 大龄程序猿
 * @create: 2020-08-15 23:59
 **/
public interface ISayHelloService {
      String   hello();
}

3、创建maven quickstart工程-springboot-dubbo-consumer ,根据接口契约，编写客户端的代码

package com.jason.dubbo.springboot;

import org.apache.dubbo.config.annotation.DubboReference;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * Hello world!
 *
 */

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

    @DubboReference
    ISayHelloService  sayHelloService;

    @RequestMapping("/say")
    public String  say()
    {
        return   sayHelloService.hello();
    }
}

application.properties

spring.application.name=spring-boot-dubbo-consumer
server.port=8089
dubbo.registry.address=nacos://192.168.213.102:8848

4、创建Spring web工程-springboot-dubbo-server,根据接口契约，编写接口实现，同时将服务发布到nacos服务注册中心

package com.jason.dubbo.springboot.springbootdubboserver.service;


import com.jason.dubbo.springboot.ISayHelloService;
import org.apache.dubbo.config.annotation.DubboService;
import org.springframework.stereotype.Service;

/**
 * @program: springcloud-dubbo
 * @description
 * @author: 大龄程序猿
 * @create: 2020-08-16 00:44
 **/

@DubboService
public class SayHelloServiceImpl implements ISayHelloService {
    @Override
    public String hello() {
        return   "Say hello  Spring-boot-dubbo";
    }
}


package com.jason.dubbo.springboot.springbootdubboserver;

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

@DubboComponentScan(basePackages = "com.jason.dubbo.springboot.springbootdubboserver.service")
@SpringBootApplication
public class SpringbootDubboServerApplication {

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

}

三、功能调试：

分别启动nacos 注册中心，同时将服务注册到nacos,客户端通过调试URL，完成服务端的接口访问：
