本文详细介绍如何在SpringBoot环境中整合Dubbo微服务框架，包括项目搭建、接口定义、服务提供与消费等步骤，实现远程服务调用。

软件版本：

Springboot2.0

Dubbo2.6

zookeeper3.4.6

废话少说，正式开始。

Step1：创建项目：使用maven新建一个DubboExample的pom工程，然后在这个parent项目下面创建三个module项目，一个DubboProvider，一个DubboConsumer，一个DubboCommon。

上图：创建DubboExample父项目

上图：创建好后的项目。

右键点击DubboExample项目，创建maven的module项目

重复上面的动作创建DubboConsumer，创建好后如下图：

Step2：DubboExample工程的pom文件修改如下：

<project xmlns="https://maven.apache.org/POM/4.0.0" xmlns:xsi="https://www.w3.org/2001/XMLSchema-instance" xsi:schemalocation="https://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

<modelversion>4.0.0</modelversion>

<parent>

<groupid>org.springframework.boot</groupid>

spring-boot-starter-parent</artifactid>

<version>2.0.3.RELEASE</version>

</parent>

<groupid>com.example</groupid>

DubboExample</artifactid>

<version>1.0.0</version>

<packaging>pom</packaging>

<name>DubboExample</name>

<description>DubboExample</description>

<modules>

<module>DubboProvider</module>

<module>DubboConsumer</module>

<module>DubboCommon</module>

</modules>

<dependencies>

<dependency>

<groupid>org.springframework.boot</groupid>

spring-boot-starter</artifactid>

</dependency>

<dependency>

<groupid>org.springframework.boot</groupid>

spring-boot-starter-test</artifactid>

<scope>test</scope>

</dependency>

<dependency>

<groupid>org.springframework.boot</groupid>

spring-boot-starter-web</artifactid>

</dependency>

<dependency>

<groupid>com.alibaba.spring.boot</groupid>

dubbo-spring-boot-starter</artifactid>

<version>2.0.0</version>

</dependency>

<dependency>

<groupid>com.101tec</groupid>

zkclient</artifactid>

<version>0.10</version>

</dependency>

</dependencies>

</project>

Step3：DubboProvider和DubboConsumer工程的pom分别添加如下内容(依赖DubboCommon工程)。

<dependencies>

<dependency>

<groupid>com.example</groupid>

DubboCommon</artifactid>

<version>0.0.1-SNAPSHOT</version>

</dependency>

</dependencies>

Step4：DubboCommon工程添加Service接口如下：

DemoService接口

DemoService.java

package com.example.service;

public interface DemoService {

public String getDemoString();

}

Step5：我们看看服务的提供者DubboProvider

ApplicationProvider.java

package com.example.provider.service;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.context.annotation.ComponentScan;

import com.alibaba.dubbo.spring.boot.annotation.EnableDubboConfiguration;

@SpringBootApplication

@ComponentScan("com.example")

@EnableDubboConfiguration

public class ApplicationProvider {

public static void main(String[] args) {

SpringApplication.run(ApplicationProvider.class, args);

}

DemoServiceImpl.java

1	`package` `com.example.provider.service;`

import org.springframework.stereotype.Component;

import com.alibaba.dubbo.config.annotation.Service;

import com.example.service.DemoService;

@Service

@Component //这个必须要加

public class DemoServiceImpl implements DemoService {

@Override

public String getDemoString() {

return "Hello Dubbo!";

}

application.properties

server.port=9092

spring.dubbo.scan.basePackages = com.example.provider.service

spring.dubbo.application.id = dubbo-dustin-demo

spring.dubbo.application.name = dubbo-dustin-demo

spring.dubbo.protocol.id = dubbo

spring.dubbo.protocol.name = dubbo

spring.dubbo.protocol.port = 12345

spring.dubbo.registry.id = my-registry

spring.dubbo.registry.address = zookeeper://127.0.0.1:2181

Step6：我们看看服务的提供者DubboConsumer

DemoController.java

package com.example.controller;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RestController;

import com.example.service.DemoService;

@RestController

@RequestMapping("demo")

public class DemoController {

@Autowired

private DemoService demoService;

@RequestMapping("index")

public String index(){

return demoService.getDemoString();

}

ApplicationConsumer.java

package com.example.system;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.context.annotation.ImportResource;

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

@SpringBootApplication

@EnableDubboConfig

@ComponentScan("com.example")

@ImportResource(locations= {"classpath:spring-dubbo.xml"}) //加载dubbo配置文件

public class ApplicationConsumer {

public static void main(String[] args) {

SpringApplication.run(ApplicationConsumer.class, args);

}

application.properties

1	`server.port=9093`

spring-dubbo.xml

<beans xmlns="https://www.springframework.org/schema/beans" xmlns:dubbo="https://code.alibabatech.com/schema/dubbo" xmlns:xsi="https://www.w3.org/2001/XMLSchema-instance" xsi:schemalocation="https://www.springframework.org/schema/beans

https://www.springframework.org/schema/beans/spring-beans.xsd

https://code.alibabatech.com/schema/dubbo

https://code.alibabatech.com/schema/dubbo/dubbo.xsd">

<dubbo:application id="dubbo-consumer-demo" name="dubbo-consumer-demo">

<dubbo:registry address="zookeeper://127.0.0.1:2181">

<dubbo:protocol id="dubbo" name="dubbo" port="12345">

<dubbo:reference id="demoService" interface="com.example.service.DemoService">

</dubbo:reference></dubbo:protocol></dubbo:registry></dubbo:application></beans>

Step7：启动zookeeper

安装启动参考文章?zookeeper安装和使用（Windows环境）

Step8：启动DubboProvider

Step8：启动DubboConsumer

Step8：测试

在搜索栏输入localhost:9093/demo/index，查看结果
