開發kettle插件環境搭建

無所不能的Java系列文章，涵蓋了Java的思想，應用開發，設計模式，程序架構等，通過我的經驗去詮釋Java的強大。

說起Java，真的有點不知道從何說起。Java是一門全領域發展的語言，從基礎的來講有4大塊，Java語法，JDK，JVM，第三方類庫。官方又以面向不同應用的角度，又把JDK分爲JavaME，JavaSE，JavaEE三個部分。Java可以做客戶端界面，可以做中間件，可以做手機系統，可以做應用，可以做工具，可以做遊戲，可以做算法…，Java幾乎無所不能。

在Java的世界裏，Java就是一切。

前言

Kettle一個開源的ETL工具，提供了一套界面操作的解決方案，從而代替原有的程序開發。但有時我們還需要開發自己的插件，來滿足我們的業務需求。Kettle基於Eclipse的架構系統，通過JAVA作爲客戶端的實現。強大的ETL功能，和圖形界面的操作，讓Kettle成爲免費的ETL工具的首選。

Kettle插件開發介紹
搭建kettle源代碼環境
在Eclipse中構建kettle項目
在Eclipse中構建插件項目
配置插件到Kettle中
Kettle項目啓動
在kettle項目集成插件源代碼

1. Kettle插件開發介紹

在我們做ETL工作的時候，在某些項目中往往會遇到一些特別的流程任務，kettle原有的流程處理節點已經不能滿足我們的要求，這時候我們就需要定製流程處理節點了。定製流程節點主要是針對數據的管理、數據的驗證和某些特別文件數據的提取。大家通過查看kettle源代碼，就可以知道怎樣去創建你自己的kettle插件了。

Kettle的插件開發，需要依賴於Kettle的源代碼環境。

2. 搭建kettle源代碼環境

1). 我的系統環境

Win7: 64bit desktop
Java: 64bit 1.6.0_45

kettle源在svn上面，我們需要下載SVN工具，然後才能下載源代碼。

2). 下載svn工具:Subversion 1.8.3 (Windows 64-bit), 註冊後下載

http://www.collab.net/downloads/subversion

3). 安裝Subversion

4). 下載kettle源代碼

下載的非常慢，不可以忍了。

查看SVN服務器位置：

~ ping source.pentaho.org
正在 Ping source.pentaho.org [74.205.95.173] 具有 32 字節的數據:
來自 74.205.95.173 的回覆: 字節=32 時間=210ms TTL=50

來自 74.205.95.173 的回覆: 字節=32 時間=210ms TTL=50

發現SVN服務器在美國！！換另外一種思路，下載源代碼！

5). 在github上面做了一個clone版

a. 在一臺美國的vps通過svn下載代碼。(30s下載完成)
b. 在github上面新建一個git項目
c. 增加gitignore屏蔽.svn目錄
d. 上傳到自己的github的庫裏面
e. 在本地的開發環境從github下載代碼

git clone https://github.com/bsspirit/kettle-4.4.0-stable.git

6). 下載完成，執行ant

雖然，有一些警告，但是build成功！！

3. 在Eclipse中構建kettle項目

7). 把kettle項目，導入到Eclipse中。

4. 在Eclipse中構建插件項目

8). 構建插件項目：我可以基於一個模板去構建插件。

下載kettle-TemplatePlugin項目

wget http://www.ahuoo.com/download/TemplateStepPlugin.rar

9). 解壓後導入到eclipse工程：kettle-TemplatePlugin

複製類庫

從kettle項目中，複製lib的*.jar到kettle-TemplatePlugin中的libext目錄
從kettle項目中，複製libswt/win64的swt.js到kettle-TemplatePlugin中的libswt/win64目錄

10). 剛纔複製的類庫加入項目依賴

11). 在kettle-TemplatePlugin項目，執行ant


~ D:\workspace\java\kettle-TemplatePlugin>ant
Buildfile: D:\workspace\java\kettle-TemplatePlugin\build.xml

init:
     [echo] Init...

     [copy] Copying 1 file to D:\workspace\java\kettle-TemplatePlugin\distrib

deploy:
     [echo] deploying plugin...

default:

BUILD SUCCESSFUL
Total time: 0 seconds

12). 修改distrib目錄的文件

icon.png：圖標文件
plugin.xml: 插件的配置文件(4.4以後的版本，可以去掉)
TemplateStepPlugin.jar：是通過ant生成的文件

5. 配置插件到Kettle中

13). 把kettle-TemplatePlugin發佈到kettle中

a. 在kettle是工程增加2個目錄


~ mkdir D:\workspace\java\kettle\distrib\plugins\steps\myPlugin
~ mkdir D:\workspace\java\kettle\plugins\steps\myPlugin

b. 修改kettle-TemplatePlugin的build.xml文件


<property name="deploydir" location="D:\workspace\java\kettle\distrib\plugins\steps\myPlugin"/>
<property name="projectdir" location="D:\workspace\java\kettle\plugins\steps\myPlugin"/>

<fileset dir="${libswt}/win64/" includes="*.jar"/>

<target name="deploy" depends="distrib" description="Deploy distribution..." >
<echo>deploying plugin...</echo>
<copy todir="${deploydir}">
<fileset dir="${distrib}" includes="**/*.*"/>
</copy>

<copy todir="${projectdir}">
<fileset dir="${distrib}" includes="**/*.*"/>
</copy>
</target>

c. kettle-TemplatePlugin項目執行ant


D:\workspace\java\kettle-TemplatePlugin>ant
Buildfile: D:\workspace\java\kettle-TemplatePlugin\build.xml

init:
     [echo] Init...

compile:
     [echo] Compiling Jasper Reporting Plugin...

copy:
     [echo] Copying images etc to classes directory...

     [echo] Generating the Jasper Reporting library TemplateStepPlugin.jar ...

distrib:
     [echo] Copying libraries to distrib directory...

deploy:
     [echo] deploying plugin...
     [copy] Copying 3 files to D:\workspace\java\kettle\distrib\plugins\steps\myPlugin
     [copy] Copying 6 files to D:\workspace\java\kettle\distrib\plugins\steps\myPlugin
     [copy] Copying 3 files to D:\workspace\java\kettle\plugins\steps\myPlugin

default:

BUILD SUCCESSFUL
Total time: 0 seconds

14). 在kettle中查看目錄：D:\workspace\java\kettle\distrib\plugins\steps\myPlugin

kettle-TemplatePlugin項目的3個文件，已經被放到了正確的位置

6. 命令行項目啓動

15). 命令行啓動kettle
a. 修改Spoon啓動命令，不開啓新窗口，直接以JAVA運行


~ vi D:\workspace\java\kettle\distrib\Spoon.bat

@echo on
REM start "Spoon" "%_PENTAHO_JAVA%" %OPT% -jar launcher\launcher.jar -lib ..\%LIBSPATH% %_cmdline%
java %OPT% -jar launcher\launcher.jar -lib ..\%LIBSPATH% %_cmdline%

b. 運行Spoon.bat命令
