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

下载的非常慢,不可以忍了。

查看SVN服务器位置:

kettle-svn

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。

    kettle-eclipse

    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

    kettle-eclipse-template

    11). 在kettle-TemplatePlugin项目,执行ant

    
    ~ D:\workspace\java\kettle-TemplatePlugin>ant
    Buildfile: D:\workspace\java\kettle-TemplatePlugin\build.xml
    
    init:
         [echo] Init...
    
    compile:
         [echo] Compiling Jasper Reporting Plugin...
        [javac] D:\workspace\java\kettle-TemplatePlugin\build.xml:40: warning: 'includeantruntime' was not set, defaulting t
    o build.sysclasspath=last; set to false for repeatable builds
    
    copy:
         [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.jar
    
    distrib:
         [echo] Copying libraries to distrib directory...
         [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>ant
    Buildfile: D:\workspace\java\kettle-TemplatePlugin\build.xml
    
    init:
         [echo] Init...
    
    compile:
         [echo] Compiling Jasper Reporting Plugin...
        [javac] D:\workspace\java\kettle-TemplatePlugin\build.xml:43: warning: 'includeantruntime' was not set, defaulting t
    o build.sysclasspath=last; set to false for repeatable builds
    
    copy:
         [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\myPlugin
    
    default:
    
    BUILD SUCCESSFUL
    Total time: 0 seconds
    

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

    kettle-dist

    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 on
    REM 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.bat
    
    DEBUG: Using JAVA_HOME
    DEBUG: _PENTAHO_JAVA_HOME=D:\toolkit\java\jdk6
    DEBUG: _PENTAHO_JAVA=D:\toolkit\java\jdk6\bin\javaw
    
    D:\workspace\java\kettle\distrib>REM start "Spoon" "D:\toolkit\java\jdk6\bin\javaw" "-Xmx512m" "-XX:MaxPermSize=256m" "-

    16). 查看kettle-TemplatePlugin 插件
    kettle-debug1

    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
    kettle-link-source

    b. 在kettle项目中编程
    kettle-source

    18). 通过Eclipse启动kettle
    a. 在Eclipse中配置启动Main Class: org.pentaho.di.ui.spoon.Spoon
    kettle-run1

    b.增加64位的swt.jar类库
    kettle-run2

    c. 在Eclipse中启动kettle
    kettle-run3

    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!!!“

    kettle-debug1

    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!!
