1、引入dubbo的jar

<dependency>
		<groupId>com.alibaba.spring.boot</groupId>
		<artifactId>dubbo-spring-boot-starter</artifactId>
		<version>2.0.0</version>
	</dependency>
	<!-- zookeeper client依赖 -->
	<dependency>
		<groupId>com.101tec</groupId>
		<artifactId>zkclient</artifactId>
		<version>0.10</version>
	</dependency>

2、连接到dubbo注册中心：

spring:
  dubbo:
    application:
      name:  spring-boot-provider
    server: true
    protocol:
      prot: 20880
      name: dubbo
    registry:
      address: 10.10.10.10:2181,10.10.10.11:2181,10.10.10.12:2181
      protocol: zookeeper

3、提供接口

4、启动类加配置

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

@EnableDubboConfiguration
