Dubbo入门实例

1.概述

Dubbo是一个分布式服务框架，致力于提供高性能和透明化的RPC远程服务调用方案，以及SOA服务治理方案

主要核心部件

Remoting: 网络通信框架，实现了sync-over-async 和 request-response 消息机制.

RPC: 一个远程过程调用的抽象，支持负载均衡、容灾和集群功能

Registry: 服务目录框架用于服务的注册和服务事件发布和订阅。

Dubbo采用全Spring配置方式，透明化接入应用，对应用没有任何API侵入，只需用Spring加载Dubbo的配置即可，Dubbo基于Spring的Schema扩展进行加载。

2.简单实例

首先maven项目增加dubbo的jar依赖，因为要用到zookeeper注册中心，也要依赖但是要去掉自带的log4j不然会默认的版本依赖jms-1.1.jarjmxtools-1.2.1.jarjmxri-1.2.1.jar等3个包，下载挺麻烦，当然如果个人已经在自己的仓库中有了就无所谓了。

com.alibaba
dubbo
2.0.13


org.apache.zookeeper
zookeeper
3.3.6


log4j
log4j




log4j
log4j
1.2.16

Spring的依赖自己添加就好了

因为要增加zookeeper的注册管理，所以如果有可用的zookeeper就用可用的zookeeper，没有可以按照如下的安装去本地安装一个。
