JAVA读取WORD,EXCEL,POWERPOINT,PDF文件的方法
http://blog.sina.com.cn/u/54c1567b010008vh
OFFICE文档使用POI控件,PDF可以使用PDFBOX0.7.3控件,完全支持中文,用XPDF也行,不过感觉PDFBOX比较好,而且作者也在更新。水平有限,万望各位指正
WORD:

public
Document getDocument(Index index, String url, String title, InputStream is)
throws
DocCenterException
...
{
String bodyText = null;
try ...{
WordExtractor ex = new WordExtractor(is);//is是WORD文件的InputStream
bodyText = ex.getText();
if(!bodyText.equals(""))...{
index.AddIndex(url, title, bodyText);
}
}catch (DocCenterException e) ...{
throw new DocCenterException("无法从该Mocriosoft Word文档中提取内容", e);

代码复制可能出错,不过代码经过测试,绝对能用,POI为3.0-rc4,PDFBOX为0.7.3
