小强源码分析系列-Dubbo-源码分析1---调试环境搭建
- 1.下载Dubbo源码
- 2.编译源码
- 3.编译完成:
- 4.代码总览:
- 5.调试入口:
1.下载Dubbo源码
fork源码到自己github仓库: [Dubbo](https://github.com/apache/incubator-dubbo)
fork源码到仓库可以随意修改代码注解,方便阅读整理。
git clone https://github.com/xxxxxxxx/incubator-dubbo.git
也可以指定下载那个分支版本
git clone --branch dubbo-2.6.6 https://github.com/xxxxxxxx/incubator-dubbo.git
2.编译源码
注：maven版本要求v3.5以上,版本比较低的可以升级下maven版本。
项目根目录输入 ：mvn install -Dmaven.test.skip=true
经过漫长的等待终于编译成功,国外maven仓库的下载速度实在是太慢啦，改成阿里云maven仓库速度便飞了起来。
3.编译完成:
生成idea项目需要命令 mvn idea:idea
生成eclipse命令需要 mvn eclipse:eclipse
启动IDE工具导入源码。
4.代码总览:
如要还没有成功，多试几次就可以了。
5.调试入口:
- 我们来打开 dubbo-demo 项目的 dubbo-demo-provider下的Provider 类，直接右键 Debug 运行main方法运行生产者。
- 我们来打开 dubbo-demo 项目的 dubbo-demo-consumer下的Consumer 类，直接右键 Debug 运行main方法运行消费者。
编译完成

3.注册中心
Demo项目中默认情况下注册中心使用的是Multicast Registry,生产环境使用的是Zookeeper Registry作为注册中心.
如果使用组播协议做为注册发现，不需要启动任何节点，只需要地址相同，就可以相互发现,可以跳过下面内容，用来调试代码一般不需要修改注册中心配置。
如果使用Zookeeper作为注册中心:
1.需要搭建Zookeeper ，启动Zookeeper服务.
2.修改 dubbo-demo-provider.xml ，启动 Provider
3.修改 dubbo-demo-consumer.xml ，启动 Consumer
启动成功后就可以调试了。
2019新的开始，新的里程碑。此系列将会持续更新，敬请关注。
