本地搭建dubbo实例

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();
}

三个项目的jar包


这里只需要spring,dubbo,zookeeper的jar包。值得注意的是在自己倒入jar包的时候,不要忘记zkclient.jar



提供者product


接口inter



消费者customer



运行步骤


运行zookeeper

zookeeper-3.4.6\bin\zkServer.cmd




运行dubbo

tomcat\bin\startup.bat





打开dubbo注册中心

其实和运行其他javaweb项目一样 :locallhost:8080/ 加项目名称即可访问。

locallhost:8080/dubbo-admin/或127.0.0.1:8080/dubbo-admin






运行生产者product测试类

右键BeginProduct.java->run as ->java application


运行消费者customer测试类

右键BeginCustomer.java->run as ->java application





查看注册中心的应用共有一个提供者,一个消费者,名称和dubbo.xml的配置一样



各自查看提供者和消费者


提供者




消费者
