dubbo2.4.11源碼編譯

本文以dubbo2.4.11源碼編譯和打包例

dubbo官網：http://dubbo.io/

源碼：https://github.com/alibaba/dubbo

用戶指南：http://dubbo.io/User+Guide-zh.htm

開發指南：http://dubbo.io/Developer+Guide-zh.htm

按官方說明2.4.X是GA穩定版本，去https://github.com/alibaba/dubbo/releases下載最新的2.4.11

解壓到D:\project\dubbo\dubbo-dubbo-2.4.11

在編譯dubbo前，先執行下面操做

1、opensesame依賴問題，可能會報Non-resolvable parent POM: Could not transfer artifact com.alibaba:opensesame:pom:2.0 from/to opensesame.releases (http://code.alibabatech.com/mvn/releases)

的錯誤。

打開https://github.com/alibaba/opensesame，下載opensesame（主要是pom.xml文件），解壓在D:\project\dubbo\opensesame-master目錄

在D:\project\dubbo\opensesame-master目錄下，cmd命令行執行

mvn clean install -Dmaven.test.skip

編譯完成後，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>

相同目錄再編譯一次opensesame

mvn clean install -Dmaven.test.skip

2、fastjson依賴包，可能報[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]錯誤

修改D:\project\dubbo\dubbo-dubbo-2.4.11\pom.xml,找到 <fastjson_version>1.1.8</fastjson_version>，將1.1.8修改成1.1.39，參考https://github.com/alibaba/dubbo/issues/22

3、註釋D:\project\dubbo\dubbo-dubbo-2.4.11\pom.xml下邊的內容

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

從github的dubbo主庫中下載hessian-lite，當前最新的dubbo源碼中已帶有hessian-lite源碼，能夠直接取出來加到dubbo 2.4.11中編譯（https://github.com/alibaba/dubbo，https://github.com/alibaba/dubbo/tree/master/hessian-lite）

把hessian-lite拷貝到D:\project\dubbo\dubbo-dubbo-2.4.11，

修改D:\project\dubbo\dubbo-dubbo-2.4.11\pom.xml，增長<module>hessian-lite</module>編譯

<modules>
	    <!-- 增長 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> 把版本號改成2.4.11，須要與當前dubbo版本號一致-->
		<version>2.4.11</version>
    </parent>

5、增長編譯dubbo管理控制檯，這一步不是必須的，主要是官方的dubbo管理控制檯下載不了，直接本身編譯一個，默認下不編譯打包dubbo-admin,須要本身增長。

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

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

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

<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>
		<!-- 增長編譯dubbo-admin管理控制檯，dubbo-simple、dubbo-demo可自行決定是否編譯 -->
		<module>dubbo-admin</module>
	</modules>

6、正式編譯dubbo

1)cmd命令行，在D:\project\dubbo\dubbo-dubbo-2.4.11目錄下執行命令：

先設置maven內存，不然編譯時會報內存不足錯誤

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目錄下執行命令：

mvn eclipse:eclipse

能夠直接在eclipse運行下邊幾個程序

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管理控制檯安裝

第6步執行完成後，D:\project\dubbo\dubbo-2.4.11\dubbo-admin\target目錄會生成dubbo-admin-2.4.11.war，

war包解壓到webapps/ROOT目錄下，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的註冊中心地址（zookeeper的安裝配置忽略）

注意：肯定zookeeper啓動後再去啓動tomcat。
