SpringBoot与Dubbo2.7.5及Nacos整合实战:以Alibaba Nacos为注册中心

项目结果如下图：

SSO-Search-Dubbo-Nacos-api 为服务接口

package com.search.dubbo.springcloud.nacos.api;

/**
 * Hello world!
 *
 */
public interface IHelloService {
    String sayHello(String name);
}

SSO-Search-Dubbo-Nacos-provider  为服务提供者

maven构建：

pom.xml配置如下

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

 启动服务提供者：查看是否nacos注册中心是否有该服务

服务消费者:
