Apache POI 解析 microsoft word 图片文字都不放过
项目需要 ，写了个 ms word 解析器，贴出来分享！
Apache POI 组件主要用来  解析 microsoft word,ppt,excel,Visio 文档 ，具体介绍看下面吧！
Overview
The following are components of the entire POI project and a brief summary of their purpose.
POIFS for OLE 2 Documents
POIFS is the oldest and most stable part of the project. It is our port of the OLE 2 Compound Document Format to pure Java. It supports both read and write functionality. All of our components ultimately rely on it by definition. Please see the POIFS project page for more information.
HSSF for Excel Documents
HSSF is our port of the Microsoft Excel 97(-2003) file format (BIFF8) to pure Java. It supports read and write capability. (Support for Excel 2007 .xlsx files is in progress). Please see the HSSF project page for more information.
HWPF for Word Documents
HWPF is our port of the Microsoft Word 97 file format to pure Java. It supports read, and limited write capabilities. Please see the HWPF project page for more information. This component is in the early stages of development. It can already read and write simple files.
Presently we are looking for a contributor to foster the HWPF development. Jump in!
HSLF for PowerPoint Documents
HSLF is our port of the Microsoft PowerPoint 97(-2003) file format to pure Java. It supports read and write capabilities. Please see the HSLF project page for more information.
HDGF for Visio Documents
HDGF is our port of the Microsoft Viso 97(-2003) file format to pure Java. It currently only supports reading at a very low level, and simple text extraction. Please see the HDGF project page for more information.
HPSF for Document Properties
HPSF is our port of the OLE 2 property set format to pure Java. Property sets are mostly use to store a document's properties (title, author, date of last modification etc.), but they can be used for application-specific purposes as well.
HPSF supports reading and writing of properties. However, you will need to be using version 3.0 of POI to utilise the write support.
Please see the HPSF project page for more information.
