     * /
    公共静态无效的主要（字串[] args）{
        // TODO自动生成方法存根        POIFSFileSystem FS =无效;
         文档的文档=新的文件（）;         尝试{
             的System.out.println（开始测试）;
             FS =新POIFSFileSystem（新的FileInputStream（/文件/ test2.doc））;             HWPFDocument DOC =新HWPFDocument（FS）;
             WordExtractor我们=新WordExtractor（DOC）;             OutputStream的文件=新的FileOutputStream（新文件（/文件/的test.pdf））;             PdfWriter作家= PdfWriter.getInstance（文档，文件）;             范围范围= doc.getRange（）;
             document.open（）;
             writer.setPageEmpty（真）;
             document.newPage（）;
             writer.setPageEmpty（真）;             的String [] =段we.getParagraphText（）;
             的for（int i = 0; I＆LT; paragraphs.length;我++）{                 org.apache.poi.hwpf.usermodel.Paragraph PR = range.getParagraph（ⅰ）;
                // CharacterRun运行= pr.getCharacterRun（I）
