在项目中有doc/docx转换成html代码，然后渲染到前端的需求，在此之前只是大概了解过poi有这方面的能力，但并未实操过。在实现过程中看过很多教程，也踩了很多坑，但时隔太久忘记了。话不多说，直接贴代码。 pom.xml引入相关jar包 fr.opensagres.xdocreport org.apache.poi.xwpf.converter.xhtml 1.0.6 org.apache.poi ooxml-schemas 1.4 org.apache.poi poi 3.10.1 org.apache.poi poi-scratchpad 3.10.1工具类 package com.common.comm.util; import org.apache.poi.hwpf.HWPFDocument; import org.apache.poi.hwpf.converter.WordToHtmlConverter; import org.apache.poi.hwpf.usermodel.Picture; import org.apache.poi.xwpf.converter.core.FileImageExtractor; import org.apache.poi.xwpf.converter.core.FileURIResolver; import org.apache.poi.xwpf.converter.xhtml.XHTMLConverter; import org.apache.poi.xwpf.converter.xhtml.XHTMLOptions; import org.apache.poi.xwpf.usermodel.XWPFDocument; import javax.servlet.http.HttpServletRequest; import javax.xml.parsers.DocumentBuilderFactory; import javax.xml.parsers.ParserConfigurationException; import javax.xml.transform.OutputKeys; import javax.xml.transform.Transformer; import javax.xml.transform.TransformerException; import javax.xml.transform.TransformerFactory; import javax.xml.transform.dom.DOMSource; import javax.xml.transform.stream.StreamResult; import java.io.*; import java.util.List; public class DocToHtml { private static final String ENCODING = "UTF-8"; /** * * @param path docx文档所在文件夹路径 * @param fileName docx文档名称 * @param request * @return 转换后的html代码 * @throws TransformerException * @throws IOException * @throws ParserConfigurationException */ public static String docToHtml(String path, String fileName, HttpServletRequest request) throws TransformerException, IOException, ParserConfigurationException { if (path == null || "".equals(path) || fileName == null || "".equals(fileName)) { return ""; } File file = new File(path + fileName); if (file.exists() && file.isFile()) { FileInputStream is = new FileInputStream(file); HWPFDocument wordDocument = new HWPFDocument(is); WordToHtmlConverter converter = new WordToHtmlConverter( DocumentBuilderFactory.newInstance().newDocumentBuilder() .newDocument()); String head = request.getRequestURL().toString().startsWith("https")?"https://":"http://"; String port = (request.getServerPort()==80||request.getServerPort()==443)?"":(":"+request.getServerPort()); String domain = head + request.getServerName() + port; converter.setPicturesManager((content, pictureType, suggestedName, widthInches, heightInches) -> domain + "/files/news/temp" + fileName + "/" + suggestedName); converter.processDocument(wordDocument); String basePath = path + "temp/" + fileName + "/"; File dir = new File(basePath); if (!dir.exists()) { dir.mkdirs(); } List pics = wordDocument.getPicturesTable().getAllPictures(); for (Picture pic : pics) { try { pic.writeImageContent(new FileOutputStream(basePath + pic.suggestFullFileName())); } catch (FileNotFoundException e) { e.printStackTrace(); } } StringWriter writer = new StringWriter(); Transformer serializer = TransformerFactory.newInstance().newTransformer(); serializer.setOutputProperty(OutputKeys.ENCODING, ENCODING); serializer.setOutputProperty(OutputKeys.INDENT, "yes"); serializer.setOutputProperty(OutputKeys.METHOD, "html"); serializer.transform( new DOMSource(converter.getDocument()), new StreamResult(writer)); writer.close(); return writer.toString(); } else { return ""; } } /** * docx转html * @param path docx文档所在文件夹路径 * @param fileName docx文档名称 * @return 转换后的html代码 * @throws Throwable */ public static String docxToHtml(String path, String fileName) throws Throwable { String fileOutName = path + "temp/" + fileName + ".html"; XWPFDocument document = new XWPFDocument(new FileInputStream(path + fileName)); XHTMLOptions options = XHTMLOptions.create(); // Extract image File imageFolder = new File(path + "/images/" + fileName); options.setExtractor(new FileImageExtractor(imageFolder)); // URI resolver options.URIResolver(new FileURIResolver(imageFolder)); OutputStream out = new FileOutputStream(new File(fileOutName)); XHTMLConverter.getInstance().convert(document, out, options); StringBuilder content = new StringBuilder(); File file = new File(fileOutName); try (BufferedReader reader = new BufferedReader(new FileReader(file))) { String tempString; while ((tempString = reader.readLine()) != null) { content.append(tempString); } reader.close(); out.close(); file.delete(); } catch (IOException e) { e.printStackTrace(); } return content.toString().replace(path, "/files/news/"); } }项目环境：JDK1.8、Spring 4.0.2.RELEASE（不知道会不会有影响，写上来以防万一） |
