本地搭建dubbo实例

来源：互联网发布：个人数据存储编辑：程序博客网时间：2024/05/21 09:07

准备工作

1.这个实例需要maven的项目依赖，如果有需要的博友，请查看我前面的文章：maven项目依赖详细步骤。

2.dubbo下载

3.zookeeper下载

项目代码

三个项目的目录结构，生产者，接口，消费者

其中接口只是提供了接口的方法，无需其他配置。而生产者和消费者需要dubbo.xml配置文件来配置。

各个项目的目录结构

接口inter

SayHelloWorldInter.java

package com.dao.chu.inter;/** *  * 第一个项目的接口 *  * @version  [版本号, 2017年1月24日] * @see  [相关类/方法] * @since  [产品/模块版本] */public interface SayHelloWorldInter{    /**     *      * sayHelloWorld方法     * @see [类、类#方法、类#成员]     */    public void sayHelloWorld();}
