2025年小强源码分析系列-Dubbo-源码分析1---调试环境搭建

大家好，我是讯享网，很高兴认识大家。

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

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

讯享网

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:

在这里插入图片描述
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。

启动成功,编译正常，开始吧。
