开发kettle插件 环境搭建

无所不能的Java系列文章，涵盖了Java的思想，应用开发，设计模式，程序架构等，通过我的经验去诠释Java的强大。

说起Java，真的有点不知道从何说起。Java是一门全领域发展的语言，从基础的来讲有4大块，Java语法，JDK，JVM，第三方类库。官方又以面向不同应用的角度，又把JDK分为JavaME，JavaSE，JavaEE三个部分。Java可以做客户端界面，可以做中间件，可以做手机系统，可以做应用，可以做工具，可以做游戏，可以做算法…，Java几乎无所不能。

在Java的世界里，Java就是一切。

前言

Kettle一个开源的ETL工具，提供了一套界面操作的解决方案，从而代替原有的程序开发。但有时我们还需要开发自己的插件，来满足我们的业务需求。Kettle基于Eclipse的架构系统，通过JAVA作为客户端的实现。强大的ETL功能，和图形界面的操作，让Kettle成为免费的ETL工具的首选。

目录

1. Kettle插件开发介绍
2. 搭建kettle源代码环境
3. 在Eclipse中构建kettle项目
4. 在Eclipse中构建插件项目
5. 配置插件到Kettle中
6. Kettle项目启动
7. 在kettle项目集成插件源代码

1. Kettle插件开发介绍

在我们做ETL工作的时候，在某些项目中往往会遇到一些特别的流程任务，kettle原有的流程处理节点已经不能满足我们的要求，这时候我们就需要定制流程处理节点了。定制流程节点主要是针对数据的管理、数据的验证和某些特别文件数据的提取。大家通过查看kettle源代码，就可以知道怎样去创建你自己的kettle插件了。

Kettle的插件开发，需要依赖于Kettle的源代码环境。

2. 搭建kettle源代码环境

1). 我的系统环境

• Win7: 64bit desktop
• Java: 64bit 1.6.0_45

kettle源在svn上面，我们需要下载SVN工具，然后才能下载源代码。

2). 下载svn工具:Subversion 1.8.3 (Windows 64-bit), 注册后下载

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

3). 安装Subversion

4). 下载kettle源代码

~ D:\workspace\java>svn co http://source.pentaho.org/svnkettleroot/Kettle/tags/4.4.0-stable/ kettleA    kettle\.directoryA    kettle\.projectA    kettle\coberturaA    kettle\cobertura\cobertura.jarA    kettle\cobertura\libA    kettle\cobertura\lib\log4j-1.2.9.jarA    kettle\cobertura\lib\LICENSEA    kettle\cobertura\lib\javancss.jarA    kettle\cobertura\lib\junit.jarA    kettle\cobertura\lib\cpl-v10.htmlA    kettle\cobertura\lib\jakarta-oro-2.0.8.jarA    kettle\cobertura\lib\asm-2.1.jarA    kettle\cobertura\lib\ccl.jarA    kettle\srcA    kettle\src\kettle-steps.xmlA    kettle\src\kettle-job-entries.xmlA    kettle\src\kettle-import-rules.xmlA    kettle\src\orgA    kettle\src\org\pentahoA    kettle\src\org\pentaho\xulA    kettle\src\org\pentaho\xul\swtA    kettle\src\org\pentaho\reportingA    kettle\src\org\pentaho\reporting\pluginA    kettle\src\org\pentaho\hadoopA    kettle\src\org\pentaho\hadoop\HadoopCompression.javaA    kettle\src\org\pentaho\diA    kettle\src\org\pentaho\di\repositoryA    kettle\src\org\pentaho\di\repository\kdrA    kettle\src\org\pentaho\di\repository\kdr\KettleDatabaseRepositorySecurityProvider.javaA    kettle\src\org\pentaho\di\repository\kdr\KettleDatabaseRepositoryCreationHelper.javaA    kettle\src\org\pentaho\di\repository\kdr\KettleDatabaseRepositoryMeta.javaA    kettle\src\org\pentaho\di\repository\kdr\KettleDatabaseRepositoryBase.javaA    kettle\src\org\pentaho\di\repository\kdr\KettleDatabaseRepository.javaA    kettle\src\org\pentaho\di\repository\kdr\delegatesA    kettle\src\org\pentaho\di\repository\kdr\delegates\KettleDatabaseRepositoryBaseDelegate.java

下载的非常慢，不可以忍了。

查看SVN服务器位置：

~ ping source.pentaho.org正在 Ping source.pentaho.org [74.205.95.173] 具有 32 字节的数据:来自 74.205.95.173 的回复: 字节=32 时间=210ms TTL=50来自 74.205.95.173 的回复: 字节=32 时间=209ms TTL=50来自 74.205.95.173 的回复: 字节=32 时间=211ms TTL=50来自 74.205.95.173 的回复: 字节=32 时间=210ms TTL=50

发现SVN服务器在美国！！换另外一种思路，下载源代码！

5). 在github上面做了一个clone版

• a. 在一台美国的vps通过svn下载代码。(30s下载完成)
• b. 在github上面新建一个git项目
• c. 增加gitignore屏蔽.svn目录
• d. 上传到自己的github的库里面
• e. 在本地的开发环境从github下载代码

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

6). 下载完成，执行ant

虽然，有一些警告，但是build成功！！

3. 在Eclipse中构建kettle项目

7). 把kettle项目，导入到Eclipse中。

4. 在Eclipse中构建插件项目

8). 构建插件项目：我可以基于一个模板去构建插件。

下载kettle-TemplatePlugin项目

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

9). 解压后导入到eclipse工程：kettle-TemplatePlugin

复制类库

• 从kettle项目中，复制lib的*.jar到kettle-TemplatePlugin中的libext目录
• 从kettle项目中，复制libswt/win64的swt.js到kettle-TemplatePlugin中的libswt/win64目录

10). 刚才复制的类库加入项目依赖

11). 在kettle-TemplatePlugin项目，执行ant

~ D:\workspace\java\kettle-TemplatePlugin>antBuildfile: D:\workspace\java\kettle-TemplatePlugin\build.xmlinit:     [echo] Init...compile:     [echo] Compiling Jasper Reporting Plugin...    [javac] D:\workspace\java\kettle-TemplatePlugin\build.xml:40: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable buildscopy:     [echo] Copying images etc to classes directory...lib:     [echo] Generating the Jasper Reporting library TemplateStepPlugin.jar ...      [jar] Building jar: D:\workspace\java\kettle-TemplatePlugin\lib\TemplateStepPlugin.jardistrib:     [echo] Copying libraries to distrib directory...     [copy] Copying 1 file to D:\workspace\java\kettle-TemplatePlugin\distribdeploy:     [echo] deploying plugin...default:BUILD SUCCESSFULTotal time: 0 seconds

12). 修改distrib目录的文件

• icon.png：图标文件
• plugin.xml: 插件的配置文件(4.4以后的版本，可以去掉)
• TemplateStepPlugin.jar：是通过ant生成的文件

5. 配置插件到Kettle中

13). 把kettle-TemplatePlugin发布到kettle中

a. 在kettle是工程增加2个目录

~ 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项目执行ant

D:\workspace\java\kettle-TemplatePlugin>antBuildfile: D:\workspace\java\kettle-TemplatePlugin\build.xmlinit:     [echo] Init...compile:     [echo] Compiling Jasper Reporting Plugin...    [javac] D:\workspace\java\kettle-TemplatePlugin\build.xml:43: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable buildscopy:     [echo] Copying images etc to classes directory...lib:     [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\myPlugindefault:BUILD SUCCESSFULTotal time: 0 seconds

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

kettle-TemplatePlugin项目的3个文件，已经被放到了正确的位置

6. 命令行项目启动

15). 命令行启动kettle
a. 修改Spoon启动命令，不开启新窗口，直接以JAVA运行

~ vi D:\workspace\java\kettle\distrib\Spoon.bat@echo onREM start "Spoon" "%_PENTAHO_JAVA%" %OPT% -jar launcher\launcher.jar -lib ..\%LIBSPATH% %_cmdline%java %OPT% -jar launcher\launcher.jar -lib ..\%LIBSPATH% %_cmdline%

b. 运行Spoon.bat命令

~ D:\workspace\java\kettle\distrib>Spoon.batDEBUG: Using JAVA_HOMEDEBUG: _PENTAHO_JAVA_HOME=D:\toolkit\java\jdk6DEBUG: _PENTAHO_JAVA=D:\toolkit\java\jdk6\bin\javawD:\workspace\java\kettle\distrib>REM start "Spoon" "D:\toolkit\java\jdk6\bin\javaw" "-Xmx512m" "-XX:MaxPermSize=256m" "-Djava.library.path=libswt\win64" "-DKETTLE_HOME=" "-DKETTLE_REPOSITORY=" "-DKETTLE_USER=" "-DKETTLE_PASSWORD=" "-DKETTLE_PLUGIN_PACKAGES=" "-DKETTLE_LOG_SIZE_LIMIT=" -jar launcher\launcher.jar -lib ..\libswt\win64D:\workspace\java\kettle\distrib>java "-Xmx512m" "-XX:MaxPermSize=256m" "-Djava.library.path=libswt\win64" "-DKETTLE_HOME=" "-DKETTLE_REPOSITORY=" "-DKETTLE_USER=" "-DKETTLE_PASSWORD=" "-DKETTLE_PLUGIN_PACKAGES=" "-DKETTLE_LOG_SIZE_LIMIT="-jar launcher\launcher.jar -lib ..\libswt\win64INFO  21-09 12:26:35,717 - Spoon - Logging goes to file:///C:/Users/ADMINI~1/AppData/Local/Temp/spoon_0042f442-2276-11e3-bf49-6be1282e1ee0.logINFO  21-09 12:26:36,655 - Spoon - 要求资源库INFO  21-09 12:26:36,795 - RepositoriesMeta - Reading repositories XML file: C:\Users\Administrator\.kettle\repositories.xmlINFO  21-09 12:26:37,783 - Version checker - OK

16). 查看kettle-TemplatePlugin 插件

7. 在kettle项目集成插件源代码

17). 通过Eclipse的 link source功能，连接kettle-TemplatePlugin项目
a. 在kettle项目中，选择link source

b. 在kettle项目中编程

18). 通过Eclipse启动kettle
a. 在Eclipse中配置启动Main Class: org.pentaho.di.ui.spoon.Spoon

b.增加64位的swt.jar类库

c. 在Eclipse中启动kettle

19). 通过Eclipse调用kettle-TemplatePlugin
a. 修改TemplateStepDialog.java，找到open方法，增加一行输出

public String open() { System.out.println(“Open a dialog!!!”);...}

b. 在Eclipse中，通过debug启动：org.pentaho.di.ui.spoon.Spoon
双点Template Plugin的图标，看到日志显示”Open a dialog!!!“

这样我们就构建好了，kettle插件的开发环境。接下来，我们就可以进行插件开发了！！

前言

Kettle一个开源的ETL工具，提供了一套界面操作的解决方案，从而代替原有的程序开发。但有时我们还需要开发自己的插件，来满足我们的业务需求。Kettle基于Eclipse的架构系统，通过JAVA作为客户端的实现。强大的ETL功能，和图形界面的操作，让Kettle成为免费的ETL工具的首选。

目录

1. Kettle插件开发介绍
2. 搭建kettle源代码环境
3. 在Eclipse中构建kettle项目
4. 在Eclipse中构建插件项目
5. 配置插件到Kettle中
6. Kettle项目启动
7. 在kettle项目集成插件源代码

1. Kettle插件开发介绍

在我们做ETL工作的时候，在某些项目中往往会遇到一些特别的流程任务，kettle原有的流程处理节点已经不能满足我们的要求，这时候我们就需要定制流程处理节点了。定制流程节点主要是针对数据的管理、数据的验证和某些特别文件数据的提取。大家通过查看kettle源代码，就可以知道怎样去创建你自己的kettle插件了。

Kettle的插件开发，需要依赖于Kettle的源代码环境。

2. 搭建kettle源代码环境

1). 我的系统环境

• Win7: 64bit desktop
• Java: 64bit 1.6.0_45

kettle源在svn上面，我们需要下载SVN工具，然后才能下载源代码。

2). 下载svn工具:Subversion 1.8.3 (Windows 64-bit), 注册后下载

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

3). 安装Subversion

4). 下载kettle源代码

~ D:\workspace\java>svn co http://source.pentaho.org/svnkettleroot/Kettle/tags/4.4.0-stable/ kettleA    kettle\.directoryA    kettle\.projectA    kettle\coberturaA    kettle\cobertura\cobertura.jarA    kettle\cobertura\libA    kettle\cobertura\lib\log4j-1.2.9.jarA    kettle\cobertura\lib\LICENSEA    kettle\cobertura\lib\javancss.jarA    kettle\cobertura\lib\junit.jarA    kettle\cobertura\lib\cpl-v10.htmlA    kettle\cobertura\lib\jakarta-oro-2.0.8.jarA    kettle\cobertura\lib\asm-2.1.jarA    kettle\cobertura\lib\ccl.jarA    kettle\srcA    kettle\src\kettle-steps.xmlA    kettle\src\kettle-job-entries.xmlA    kettle\src\kettle-import-rules.xmlA    kettle\src\orgA    kettle\src\org\pentahoA    kettle\src\org\pentaho\xulA    kettle\src\org\pentaho\xul\swtA    kettle\src\org\pentaho\reportingA    kettle\src\org\pentaho\reporting\pluginA    kettle\src\org\pentaho\hadoopA    kettle\src\org\pentaho\hadoop\HadoopCompression.javaA    kettle\src\org\pentaho\diA    kettle\src\org\pentaho\di\repositoryA    kettle\src\org\pentaho\di\repository\kdrA    kettle\src\org\pentaho\di\repository\kdr\KettleDatabaseRepositorySecurityProvider.javaA    kettle\src\org\pentaho\di\repository\kdr\KettleDatabaseRepositoryCreationHelper.javaA    kettle\src\org\pentaho\di\repository\kdr\KettleDatabaseRepositoryMeta.javaA    kettle\src\org\pentaho\di\repository\kdr\KettleDatabaseRepositoryBase.javaA    kettle\src\org\pentaho\di\repository\kdr\KettleDatabaseRepository.javaA    kettle\src\org\pentaho\di\repository\kdr\delegatesA    kettle\src\org\pentaho\di\repository\kdr\delegates\KettleDatabaseRepositoryBaseDelegate.java

下载的非常慢，不可以忍了。

查看SVN服务器位置：

~ ping source.pentaho.org正在 Ping source.pentaho.org [74.205.95.173] 具有 32 字节的数据:来自 74.205.95.173 的回复: 字节=32 时间=210ms TTL=50来自 74.205.95.173 的回复: 字节=32 时间=209ms TTL=50来自 74.205.95.173 的回复: 字节=32 时间=211ms TTL=50来自 74.205.95.173 的回复: 字节=32 时间=210ms TTL=50

发现SVN服务器在美国！！换另外一种思路，下载源代码！

5). 在github上面做了一个clone版

• a. 在一台美国的vps通过svn下载代码。(30s下载完成)
• b. 在github上面新建一个git项目
• c. 增加gitignore屏蔽.svn目录
• d. 上传到自己的github的库里面
• e. 在本地的开发环境从github下载代码

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

6). 下载完成，执行ant

虽然，有一些警告，但是build成功！！

3. 在Eclipse中构建kettle项目

7). 把kettle项目，导入到Eclipse中。

4. 在Eclipse中构建插件项目

8). 构建插件项目：我可以基于一个模板去构建插件。

下载kettle-TemplatePlugin项目

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

9). 解压后导入到eclipse工程：kettle-TemplatePlugin

复制类库

• 从kettle项目中，复制lib的*.jar到kettle-TemplatePlugin中的libext目录
• 从kettle项目中，复制libswt/win64的swt.js到kettle-TemplatePlugin中的libswt/win64目录

10). 刚才复制的类库加入项目依赖

11). 在kettle-TemplatePlugin项目，执行ant

~ D:\workspace\java\kettle-TemplatePlugin>antBuildfile: D:\workspace\java\kettle-TemplatePlugin\build.xmlinit:     [echo] Init...compile:     [echo] Compiling Jasper Reporting Plugin...    [javac] D:\workspace\java\kettle-TemplatePlugin\build.xml:40: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable buildscopy:     [echo] Copying images etc to classes directory...lib:     [echo] Generating the Jasper Reporting library TemplateStepPlugin.jar ...      [jar] Building jar: D:\workspace\java\kettle-TemplatePlugin\lib\TemplateStepPlugin.jardistrib:     [echo] Copying libraries to distrib directory...     [copy] Copying 1 file to D:\workspace\java\kettle-TemplatePlugin\distribdeploy:     [echo] deploying plugin...default:BUILD SUCCESSFULTotal time: 0 seconds

12). 修改distrib目录的文件

• icon.png：图标文件
• plugin.xml: 插件的配置文件(4.4以后的版本，可以去掉)
• TemplateStepPlugin.jar：是通过ant生成的文件

5. 配置插件到Kettle中

13). 把kettle-TemplatePlugin发布到kettle中

a. 在kettle是工程增加2个目录

~ 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项目执行ant

D:\workspace\java\kettle-TemplatePlugin>antBuildfile: D:\workspace\java\kettle-TemplatePlugin\build.xmlinit:     [echo] Init...compile:     [echo] Compiling Jasper Reporting Plugin...    [javac] D:\workspace\java\kettle-TemplatePlugin\build.xml:43: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable buildscopy:     [echo] Copying images etc to classes directory...lib:     [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\myPlugindefault:BUILD SUCCESSFULTotal time: 0 seconds

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

kettle-TemplatePlugin项目的3个文件，已经被放到了正确的位置

6. 命令行项目启动

15). 命令行启动kettle
a. 修改Spoon启动命令，不开启新窗口，直接以JAVA运行

~ vi D:\workspace\java\kettle\distrib\Spoon.bat@echo onREM start "Spoon" "%_PENTAHO_JAVA%" %OPT% -jar launcher\launcher.jar -lib ..\%LIBSPATH% %_cmdline%java %OPT% -jar launcher\launcher.jar -lib ..\%LIBSPATH% %_cmdline%

b. 运行Spoon.bat命令

~ D:\workspace\java\kettle\distrib>Spoon.batDEBUG: Using JAVA_HOMEDEBUG: _PENTAHO_JAVA_HOME=D:\toolkit\java\jdk6DEBUG: _PENTAHO_JAVA=D:\toolkit\java\jdk6\bin\javawD:\workspace\java\kettle\distrib>REM start "Spoon" "D:\toolkit\java\jdk6\bin\javaw" "-Xmx512m" "-XX:MaxPermSize=256m" "-Djava.library.path=libswt\win64" "-DKETTLE_HOME=" "-DKETTLE_REPOSITORY=" "-DKETTLE_USER=" "-DKETTLE_PASSWORD=" "-DKETTLE_PLUGIN_PACKAGES=" "-DKETTLE_LOG_SIZE_LIMIT=" -jar launcher\launcher.jar -lib ..\libswt\win64D:\workspace\java\kettle\distrib>java "-Xmx512m" "-XX:MaxPermSize=256m" "-Djava.library.path=libswt\win64" "-DKETTLE_HOME=" "-DKETTLE_REPOSITORY=" "-DKETTLE_USER=" "-DKETTLE_PASSWORD=" "-DKETTLE_PLUGIN_PACKAGES=" "-DKETTLE_LOG_SIZE_LIMIT="-jar launcher\launcher.jar -lib ..\libswt\win64INFO  21-09 12:26:35,717 - Spoon - Logging goes to file:///C:/Users/ADMINI~1/AppData/Local/Temp/spoon_0042f442-2276-11e3-bf49-6be1282e1ee0.logINFO  21-09 12:26:36,655 - Spoon - 要求资源库INFO  21-09 12:26:36,795 - RepositoriesMeta - Reading repositories XML file: C:\Users\Administrator\.kettle\repositories.xmlINFO  21-09 12:26:37,783 - Version checker - OK

16). 查看kettle-TemplatePlugin 插件

7. 在kettle项目集成插件源代码

17). 通过Eclipse的 link source功能，连接kettle-TemplatePlugin项目
a. 在kettle项目中，选择link source

b. 在kettle项目中编程

18). 通过Eclipse启动kettle
a. 在Eclipse中配置启动Main Class: org.pentaho.di.ui.spoon.Spoon

b.增加64位的swt.jar类库

c. 在Eclipse中启动kettle

19). 通过Eclipse调用kettle-TemplatePlugin
a. 修改TemplateStepDialog.java，找到open方法，增加一行输出

public String open() { System.out.println(“Open a dialog!!!”);...}

b. 在Eclipse中，通过debug启动：org.pentaho.di.ui.spoon.Spoon
双点Template Plugin的图标，看到日志显示”Open a dialog!!!“

这样我们就构建好了，kettle插件的开发环境。接下来，我们就可以进行插件开发了！！
