Dubbo环境搭建之二 调用者

接口

package com.erlizhinian.demo;

public interface DemoService {

String sayHello(String name2);

}

配置

<!-- 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 -->

调用

package com.erlizhinian.main;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.erlizhinian.demo.DemoService;

public class Consumer {

public static void main(String[] args) throws Exception {

ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(
new String[] { "classpath:consumer.xml" });
context.start();
DemoService demoService = null;
String hello = null;
demoService = (DemoService) context.getBean("demoService"); // 获取远程服务代理
hello = demoService.sayHello("world"); // 执行远程方法
System.out.println(hello); // 显示调用结果

}
