新建dubbo-demo-consumer.xml

    <!--消费方应用名，用于计算依赖关系，不是匹配条件，不要与提供方一样 -->
    <dubbo:application name="demo-consumer"/>

    <!--使用zookeeper注册中心暴露服务地址 -->

Java代码

DemoProviderService.java

package service;

/**
 * 服务提供者接口
 *
 * @author LeDao
 * @company
 * @create 2021-08-10 2:02
 */
public interface DemoProviderService {

    /**
     * 测试接口
     *
     * @param name
     * @return
     */
    String sayHello(String name);
}

测试代码

import org.springframework.context.support.ClassPathXmlApplicationContext;
import service.DemoProviderService;

import java.io.IOException;

/**
 * @author LeDao
 * @company
 * @create 2021-08-10 2:03

public class Test {

    public static void main(String[] args) {

        context.start();
        DemoProviderService demoProviderService = (DemoProviderService) context.getBean("demoProviderService");
        String result = demoProviderService.sayHello("小米");
        System.out.println("远程调用的结果：" + result);
        try {
            System.in.read();
        } catch (IOException e) {
            e.printStackTrace();
        }
        context.close();
    }
}
