前言

本篇将通过搭建简单demo来讲解dubbo的使用。
官方文档

在这里插入图片描述

环境要求：

apache-zookeeper-3.5.6 :dubbo的注册中心

dubbo-2.4.9

dubbo-admin :查看服务的提供方与消费方

项目结构图

在这里插入图片描述

dubbo-api ：接口定义模块
dubbo-provider :服务提供方模块
dubbo-consumer:服务消费者模块

一、搭建项目

建立TestService接口类

package com.yi;

/**
 * 接口
 */
public interface TestService {

    String SayHello(String word);
}

在这里插入图片描述

建立TestServiceImpl实现类，对dubbo-api中接口进行实现。

package com.yi;

import org.springframework.stereotype.Service;

@Service("testService")
public class TestServiceImpl implements TestService {

    @Override
    public String SayHello(String word) {
        return word;
    }
}

在这里插入图片描述

dubbo-provider.xml

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       http://code.alibabatech.com/schema/dubbo
       http://code.alibabatech.com/schema/dubbo/dubbo.xsd">

<!-- 提供方应用信息，当前项目在整个分布式架构里面的唯一名称,用于计算依赖关系 -->
    <dubbo:application name="dubbo_provider" owner="yi">
        <dubbo:parameter key="qos.enable" value="true"/>
        <dubbo:parameter key="qos.accept.foreign.ip" value="false"/>
        <dubbo:parameter key="qos.port" value="55555"/>
    </dubbo:application>

    <!--dubbo这个服务所要暴露的服务地址所对应的注册中心-->
    <!-- 使用zookeeper注册中心暴露服务地址 -->
    <dubbo:registry address="zookeeper://127.0.0.1:2181" />

    <!--N/A 表示由 dubbo 自动分配地址 ,这里也可以通过直连的方式，不通过注册中心-->
    <!--<dubbo:registry address="N/A" />-->

    <!--当前服务发布所依赖的协议；支持多种协议：webserovice、Thrift、Hessain、http-->
    <!-- 这里采用dubbo协议在20880端口暴露服务 -->
    <dubbo:protocol name="dubbo" port="20880" />

    <!-- 声明需要暴露的服务接口 -->
    <dubbo:service interface="com.yi.TestService" ref="testService" />
</beans>

① dubbo配置文件类型spring配置

② 节点：dubbo:application 就是整个项目在分布式架构中的唯一名称，可以在 name 属性中配置，另外还可以配置 owner 字段，表示属于谁。 下面的参数是可以不配置的，这里配置是因为出现了端口的冲突，所以配置。

③ 节点：dubbo:monitor 监控中心配置， 用于配置连接监控中心相关信息，可以不配置，不是必须的参数。

④ 节点：dubbo:registry 配置注册中心的信息，比如，这里我们可以配置 zookeeper 作为我们的注册中心。 address 是注册中心的地址，这里我们配置的是 N/A 表示由 dubbo 自动分配地址。或者说是一种直连的方式，不通过注册中心。

⑤ 节点：dubbo:protocol 服务发布的时候 dubbo 依赖什么协议，可以配置 dubbo、webserovice、Thrift、Hessain、http等协议。

⑥ 节点：dubbo:service 这个节点就是我们的重点了，当我们服务发布的时候，我们就是通过这个配置将我们的服务发布出去的。 interface 是接口的包路径， ref 是第 ⑦ 点配置的接口的 bean。

⑦ 最后，我们需要像配置 spring 的接口一样，配置接口的 bean。

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

        context.start();
        System.out.println("dubbo_provider 已启动！");
        try {
            System.in.read();	// 按任意键退出
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

启动dubbo-admin
