dubbo源码编译和打包

本文以dubbo2.4.11源码编译和打包例

dubbo官网：http://dubbo.io/

源码：https://github.com/alibaba/dubbo

用户指南：http://dubbo.io/User+Guide-zh.htm

开发指南：http://dubbo.io/Developer+Guide-zh.htm

按官方说明2.4.X是GA稳定版本，去https://github.com/alibaba/dubbo/releases下载最新的2.4.11

解压到D:\project\dubbo\dubbo-dubbo-2.4.11

在编译dubbo前，先执行下面操作

1、opensesame依赖问题，可能会报Non-resolvable parent POM: Could not transfer artifact com.alibaba:opensesame:pom:2.0 from/to opensesame.releases (http://code.alibabatech.com/mvn/releases)

的错误。

打开https://github.com/alibaba/opensesame，下载opensesame（主要是pom.xml文件），解压在D:\project\dubbo\opensesame-master目录

在D:\project\dubbo\opensesame-master目录下，cmd命令行执行
mvn clean install -Dmaven.test.skip

编译完成后，修改D:\project\dubbo\opensesame-master\pom.xml,把版本2.0修改为1.0，
com.alibaba
    opensesame
   
    1.0
    pom

相同目录再编译一次opensesame
mvn clean install -Dmaven.test.skip

2、fastjson依赖包，可能报[ERROR] Failed to execute goal on project dubbo-common: Could not resolve dependencies for project com.alibaba:dubbo-common:jar:2.5.4-SNAPSHOT: Could not find artifact com.alibaba:fastjson:jar:1.1.8 in ibiblio.org (http://mirrors.ibiblio.org/pub/mirrors/maven2) -> [Help 1]错误

修改D:\project\dubbo\dubbo-dubbo-2.4.11\pom.xml,找到 1.1.8，将1.1.8修改为1.1.39，参考https://github.com/alibaba/dubbo/issues/22

3、注释D:\project\dubbo\dubbo-dubbo-2.4.11\pom.xml下边的内容
  
   
     opensesame.releases
     http://code.alibabatech.com/mvn/releases
    
      true
    
    
      false
    
   
 

4、hessian-lite依赖包，Unable to find resource 'com.alibaba:hessian-lite:jar:3.2.1-fixed-2' in repository central.repo (http://repo1.maven.org/maven2)

从github的dubbo主库中下载hessian-lite，当前最新的dubbo源码中已带有hessian-lite源码，可以直接取出来加到dubbo 2.4.11中编译（https://github.com/alibaba/dubbo，https://github.com/alibaba/dubbo/tree/master/hessian-lite）

把hessian-lite拷贝到D:\project\dubbo\dubbo-dubbo-2.4.11，

修改D:\project\dubbo\dubbo-dubbo-2.4.11\pom.xml，增加hessian-lite编译

    
     hessian-lite
 
    dubbo-common
    dubbo-container
    dubbo-remoting
    dubbo-rpc
    dubbo-filter
    dubbo-cluster
    dubbo-registry
    dubbo-monitor
    dubbo-config
    dubbo
  

修改D:\project\dubbo\dubbo-2.4.11\hessian-lite\pom.xml
  
        com.alibaba
        dubbo-parent
       
     2.4.11
   

5、增加编译dubbo管理控制台，这一步不是必须的，主要是官方的dubbo管理控制台下载不了，直接自己编译一个，默认下不编译打包dubbo-admin,需要自己增加。

修改D:\project\dubbo\dubbo-2.4.11\dubbo-admin\pom.xml文件，把版本号改为2.4.11
 
   com.alibaba
   dubbo-parent
  
   2.4.11
 

修改D:\project\dubbo\dubbo-dubbo-2.4.11\pom.xml，增加dubbo-admin编译

  hessian-lite
  dubbo-common
  dubbo-container
  dubbo-remoting
  dubbo-rpc
  dubbo-filter
  dubbo-cluster
  dubbo-registry
  dubbo-monitor
  dubbo-config
  dubbo
 
  dubbo-admin
 

6、正式编译dubbo

1)cmd命令行，在D:\project\dubbo\dubbo-dubbo-2.4.11目录下执行命令：

先设置maven内存，否则编译时会报内存不足错误
set MAVEN_OPTS=-Xmx1024m -XX:MaxPermSize=512m
mvn clean install -Dmaven.test.skip

7、添加eclipse支持

在D:\project\dubbo\dubbo-dubbo-2.4.11目录下执行命令：
mvn eclipse:eclipse

可以直接在eclipse运行下边几个程序

dubbo-demo-provider/src/test/java/com.alibaba.dubbo.demo.provider.DemoProvider

dubbo-demo-consumer/src/test/java/com.alibaba.dubbo.demo.consumer.DemoConsumer

dubbo-monitor-simple/src/test/java/com.alibaba.dubbo.monitor.simple.SimpleMonitor

dubbo-registry-simple/src/test/java/com.alibaba.dubbo.registry.simple.SimpleRegistry

8、dubbo-admin管理控制台安装

第6步执行完成后，D:\project\dubbo\dubbo-2.4.11\dubbo-admin\target目录会生成dubbo-admin-2.4.11.war，

war包解压到webapps/ROOT目录下，修改WEB-INF\dubbo.properties，
dubbo.registry.address=zookeeper://127.0.0.1:2181
dubbo.admin.root.password=root
dubbo.admin.guest.password=guest

dubbo.properties配置zookeeper的注册中心地址（zookeeper的安装配置忽略）

注意：确定zookeeper启动后再去启动tomcat。
