一 、关于Kettle
Kettle是一款国外开源的ETL工具，纯java编写，数据抽取高效稳定的数据迁移工具。Kettle中有两种脚本文件，transformation和job，transformation完成针对数据的基础转换，job则完成整个工作流程的控制。易于使用，学习成本低。
二、本示例目的
能完成ASCii编码到UTF8编码的转换。
可高效的完成批量数据的转移。
能记录、查看（最好能给出分析）转移过程中失败的数据。
学会Kettle基本使用操作
三、软件获取
在官网http://kettle.pentaho.com/下载，该软件为绿色版，解压后点击Spoon.bat运行，需要JRE环境支持。（此文档中使用4.2.0 stable版本示例）
四、主要操作区
Kettle左侧的功能区有“主对象树”和“核心对象”两个面板。其中“核心对象”较为常用。右侧为对象的属性编辑区。可以将左侧的对象拖动到右侧编辑区。同时按键盘shift键在两个对象上画线，可连接两个对象。多个对象连接成为一个transformation。
五、具体demo实现，
不写了，直接去下载附件吧~
