apache poi 转换器的编码问题 [英] Encoding issue with apache poi converter
本文介绍了apache poi 转换器的编码问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个 ms word doc 文件，我正在使用 apache poi 将其转换为 html 文档.
这是我正在运行的代码
InputStream input = new FileInputStream (path);HWPFDocument wordDocument = 新的 HWPFDocument(输入)；WordToHtmlConverter wordToHtmlConverter = new WordToHtmlConverter (DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument());列表<图片>图片 = wordDocument.getPicturesTable().getAllPictures();如果(图片！= null){for (int i = 0; i <pics.size(); i++){图片 pic = (Picture) pics.get (i);尝试{pic.writeImageContent (new FileOutputStream (path + pic.hashCode() + '.' + pic.suggestFileExtension());}catch (FileNotFoundException e){e.printStackTrace();}}}wordToHtmlConverter.setPicturesManager (new PicturesManager(){public String savePicture (byte[] content, PictureType pictureType, StringSuggestName, float widthInches, float heightInches){for(图片图片名称:图片){返回 Integer.toString(picName.hashCode()) + '.'+ picName.suggestFileExtension();}返回空；}});wordToHtmlConverter.processDocument(wordDocument);文档 htmlDocument = wordToHtmlConverter.getDocument();ByteArrayOutputStream outStream = new ByteArrayOutputStream();DOMSource domSource = new DOMSource(htmlDocument);StreamResult streamResult = new StreamResult (outStream);TransformerFactory tf = TransformerFactory.newInstance();变压器序列化器 = tf.newTransformer();serializer.setOutputProperty (OutputKeys.ENCODING, "gbk");serializer.setOutputProperty (OutputKeys.INDENT, "yes");serializer.setOutputProperty (OutputKeys.METHOD, "html");serializer.transform (domSource, streamResult);outStream.close();String html = new String (outStream.toByteArray());代码工作正常，它保留了图像和样式.但是，html 中的某些字符似乎存在问题，它没有正确编码.例如，原始 .doc 文件中的某些项目符号样式无法正确输出.我试过多个字符集(ASCII、UTF-8、gbk ...)都没有正确生成项目符号.
我 %99% 确定由于编码，项目符号显示乱码.有人用apache遇到过这样的问题吗?
解决方案
这不是编码问题，而是字体问题.Word 使用 ANSI 代码和特殊字体作为其默认项目符号列表.例如，第一个项目符号是字体Symbol"中的项目符号.第二个要点是字体Courier New"中的一个圆圈，第三个要点是字体Wingdings"中的一个正方形.
因此，最简单的可能性就是将项目符号文本的 ANSI 代码替换为 unicode.完成后，我们可以对 HTML 使用 UTF-8.
