OpenDaylight開發hello-world項目之功能實現

 

在上一節中將ODL的開發工具都裝好，mvn是生成ODL框架的管理器。在本節中使用mvn構建ODL開發的代碼框架。 

 

一、生成ODL代碼框架

maven工具根據上一節中設置的setting文件生成ODL的框架代碼。使用代碼框架的好處是不用從零開始寫，框架將基礎的代碼寫好，我們只需要關注自己的業務代碼。

mvn archetype:generate -DarchetypeGroupId=org.opendaylight.controller -DarchetypeArtifactId=opendaylight-startup-archetype -DarchetypeVersion=1.3.0-Carbon

root@vm:~# mvn org.apache.maven.plugins:maven-archetype-plugin:2.4:generate -DarchetypeGroupId=org.opendaylight.controller -DarchetypeArtifactId=opendaylight-startup-archetype -DarchetypeRepository=https://nexus.opendaylight.org/content/repositories/public -DarchetypeVersion=1.3.2-Carbon

當命令執行結束之后，會生成一個ODL的代碼框架。具體內容有如下：

 

文件名	功能
api	Yang模型目錄
artifacts	項目組件坐標管理
cli	部署的配置文件
features	feature組織管理目錄
impl	業務邏輯的代碼實現目錄
it	集成測試
karaf	karaf打包目錄
pom.xml	maven項目的基本信息描述文件

 

 

 

 

 

 

 

 

 

 

 

 

 

 

二、編譯ODL框架代碼

將ODL框架代碼編譯之后就能運能一個最簡單的ODL控制器，該控制器沒有任何多余功能。

提示：這個過程會持續半個小時以上時間，並且可能會連接超時而報錯，具體長短取決於你的機器性能和網絡。確保你在執行這個動作之前是在工程的根目錄下。

mvn clean install -DskipTests -Dmaven.javadoc.skip=true -Dcheckstyle.skip=true

 參數:
-DskipTests表示不執行測試用例
-Dmaven.javadoc.skip=true表示跳過javadoc
-Dcheckstyle.skip=true表示跳過checkstyle檢查

  

root@vm:~/topology# pwd
/root/example
root@vm:~/topology# mvn clean install -DskipTests -Dmaven.javadoc.skip=true -Dcheckstyle.skip=true

三、編譯完成

當編譯完成之后，文件夾下會生成target

 

 

啟動ODL控制器

進入bin目錄下，運行./karaf腳本，啟動ODL控制器。

 

 

查看此時安裝的插件，只有簡單的UI，命令行，API等。

 

 

ODL界面

 

  

 

簡單總結一下本篇的內容。本篇主要是下載ODL框架代碼，然后編譯java源碼，生成一個最簡單的ODL控制器。本篇還有到ODL的功能開發，所有該ODL只有最簡單的插件。
