初识Dubbo及工程(一)

本章节将会介绍dubbo 2.7.1的项目工程结构，以及一个简单的helloworld来运行，让读者对dubbo有一个更加直观的了解。

项目结构：

dubbo-common	公共逻辑子项目，定义了各子项目中通用的组件和工具类，如：IO、日志、配置处理等。
dubbo-rpc	分布式协调服务框架的核心，该模块定义了 RPC 相关的组件，包括服务发布、服务调用代理、远程调用结果、RPC 调用网络协议，RPC 调用监听器和过滤器等等。该模块提供了默认的基于 dubbo 协议的实现，还提供了 hessian、http、rmi、及 webservice 等协议的实现，能够满足绝大多数项目的使用需求，另外还提供了对自定义协议的扩展。
dubbo-registry	注册中心子项目，它是 RPC 中 consumer 服务消费者和 provider 服务提供者两个重要角色的协调者，该子项目定义了核心的注册中心组件，提供了 mutilcast、redis 和 zookeeper 等多种方式的注册中心实现，用于不同的使用场景。当然，几乎所有的项目都会选择基于 zookeeper 的实现。
dubbo-remoting	远程通讯子项目，RPC 的实现基础就是远程通讯，consmer 要调用 provider 的远程方法必须通过远程通讯实现。该模块定义了远程传输器、endpoint 终端、客户端、服务端、编码解码器、数据交换、缓冲区、通讯异常定义等核心组件。他是对于远程网络通讯的抽象，提供了诸如 netty、mina、http 等协议和技术框架的实现方式。
dubbo-monitor	监控子项目，该模块可以监控服务调用的各种信息，例如调用耗时、调用量、调用结果等等，监控中心在调用过程中收集调用的信息，发送到监控服务，在监控服务中可以存储这些信息，对这些数据进行统计分析和展示。dubbo 默认提供了一个实现，该实现非常简单，只是作为默认的实现范例，生产环境使用价值不高，往往需要自行实现。
dubbo-container	容器子项目，是一个独立的容器，以简单的 Main(类) 加载 Spring 启动，因为服务通常不需要 Tomcat/JBoss 等 Web 容器的特性，没必要用 Web 容器去加载服务。
dubbo-config	配置中心子项目，该模块通过配置信息，将 dubbo 组件的各个模块整合在一起，给框架的使用者提供可配置的、易用的分布式服务框架。它定义了面向 dubbo 使用者的各种信息配置，比如服务发布配置、方法发布配置、服务消费配置、应用程序配置、注册中心配置、协议配置、监控配置等等。
dubbo-cluster	集群子项目，将多个服务提供方伪装为一个提供方，包括：负载均衡、容错、路由等，集群的地址列表可以是静态配置的，也可以是由注册中心下发。
dubbo-admin	该子项目是一个 web 应用，可以独立部署，用于管理 dubbo 服务，该管理应用可以连接注册中心，读取和更新注册中心中的内容。

Demo

1 安装zk

安装且启动成功后：

2 在dubbo-demo下的dubbo-demo-api下面分别写一个服务提供者和服务消费者

服务提供者

package com.alibaba.dubbo.config;

import com.alibaba.dubbo.config.api.DemoService;
import com.alibaba.dubbo.config.provider.impl.DemoServiceImpl;

import java.io.IOException;

public class DubboDemoForProvider {

    public static void main(String[] args) throws IOException {
        ServiceConfig<DemoServiceImpl> service = new ServiceConfig<DemoServiceImpl>();
        service.setApplication(new ApplicationConfig("dubbo-demo-api-provider"));
        service.setRegistry(new RegistryConfig("zookeeper://127.0.0.1:2181"));
        service.setInterface(DemoService.class);
        service.setRef(new DemoServiceImpl());
        service.export();
        System.in.read();
    }
}

服务消费者

package com.alibaba.dubbo.config;

import com.alibaba.dubbo.config.api.DemoService;

public class DubboDemoForConsumer {
    public static void main(String[] args) {
        ReferenceConfig<DemoService> reference = new ReferenceConfig<DemoService>();
        reference.setApplication(new ApplicationConfig("dubbo-demo-api-consumer"));
        reference.setRegistry(new RegistryConfig("zookeeper://localhost:2181"));
        reference.setInterface(DemoService.class);
        DemoService service = reference.get();
        String message = service.sayName("dubbo");
        System.out.println(message);
    }
}

服务提供者运行日志
