标题: JAVA读取WORD,EXCEL,POWERPOINT,PDF文件的方法
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: import org.apache.lucene.document.Document; import org.apache.lucene.document.Field; import org.apache.poi.hwpf.extractor.WordExtractor;

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);
