dubbo源码编译

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，先执行下面操做

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修改成1.0，

<groupId>com.alibaba</groupId>
    <artifactId>opensesame</artifactId>
    <!-- 2.0修改成1.0 -->
    <version>1.0</version> 
    <packaging>pom</packaging>

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 <fastjson_version>1.1.8</fastjson_version>，将1.1.8修改成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

        <repositories>
        <repository>
            <id>opensesame.releases</id>
            <url>http://code.alibabatech.com/mvn/releases</url>
            <releases>
                <enabled>true</enabled>
            </releases>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
        </repository>
    </repositories>

 

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，能够直接取出来加到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，增长<module>hessian-lite</module>编译

<modules>
        <!-- 增长 hessian-lite-->
        <module>hessian-lite</module>
        
        <module>dubbo-common</module>
        <module>dubbo-container</module>
        <module>dubbo-remoting</module>
        <module>dubbo-rpc</module>
        <module>dubbo-filter</module>
        <module>dubbo-cluster</module>
        <module>dubbo-registry</module>
        <module>dubbo-monitor</module>
        <module>dubbo-config</module>
        <module>dubbo</module>
    </modules>

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

<parent>
        <groupId>com.alibaba</groupId>
        <artifactId>dubbo-parent</artifactId>
        <!--<version>2.5.4-SNAPSHOT</version> 把版本号改成2.4.11，须要与当前dubbo版本号一致-->
        <version>2.4.11</version>
    </parent>

 

5、增长编译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，直接本身编译一个，默认下不编译打包dubbo-admin,须要本身增长。

修改D:\project\dubbo\dubbo-2.4.11\dubbo-admin\pom.xml文件，把版本号改成2.4.11

<parent>
        <groupId>com.alibaba</groupId>
        <artifactId>dubbo-parent</artifactId>
        <!-- <version>2.4.10</version> 版本号修改成2.4.11 -->
        <version>2.4.11</version>
    </parent>

修改D:\project\dubbo\dubbo-dubbo-2.4.11\pom.xml，增长<module>dubbo-admin</module>编译

<modules>
        <module>hessian-lite</module>
        <module>dubbo-common</module>
        <module>dubbo-container</module>
        <module>dubbo-remoting</module>
        <module>dubbo-rpc</module>
        <module>dubbo-filter</module>
        <module>dubbo-cluster</module>
        <module>dubbo-registry</module>
        <module>dubbo-monitor</module>
        <module>dubbo-config</module>
        <module>dubbo</module>
        <!-- 增长编译dubbo-admin管理控制台，dubbo-simple、dubbo-demo可自行决定是否编译 -->
        <module>dubbo-admin</module>
    </modules>

 

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，不然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

能够直接在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：肯定zookeeper启动后再去启动tomcat。
