POI转HTML（仅针对doc）：

package com.vito.demo.test;        import java.io.ByteArrayOutputStream;        import java.io.File;        import java.io.FileInputStream;        import java.io.FileNotFoundException;        import java.io.FileOutputStream;        import java.io.InputStream;        import java.util.List;        import javax.xml.parsers.DocumentBuilderFactory;        import javax.xml.transform.OutputKeys;        import javax.xml.transform.Transformer;        import javax.xml.transform.TransformerFactory;        import javax.xml.transform.dom.DOMSource;        import javax.xml.transform.stream.StreamResult;        import org.apache.commons.io.FileUtils;        import org.apache.poi.hwpf.HWPFDocument;        import org.apache.poi.hwpf.converter.PicturesManager;        import org.apache.poi.hwpf.converter.WordToHtmlConverter;        import org.apache.poi.hwpf.usermodel.Picture;        import org.apache.poi.hwpf.usermodel.PictureType;        import org.w3c.dom.Document;public class PoiWordToHtml {    public static void main(String[] args) throws Throwable {        final String path = "G:\\doc\\";        final String file = "客户需求文档.doc";InputStream input = new FileInputStream(path + file);HWPFDocument wordDocument = new HWPFDocument(input);WordToHtmlConverter wordToHtmlConverter = new WordToHtmlConverter(                DocumentBuilderFactory.newInstance().newDocumentBuilder()                        .newDocument());wordToHtmlConverter.setPicturesManager(new PicturesManager() {            public String savePicture(byte[] content, PictureType pictureType,String suggestedName, float widthInches, float heightInches) {                return suggestedName;}        });wordToHtmlConverter.processDocument(wordDocument);List pics = wordDocument.getPicturesTable().getAllPictures();        if (pics != null) {            for (int i = 0; i < pics.size(); i++) {                Picture pic = (Picture) pics.get(i);                try {                    pic.writeImageContent(new FileOutputStream(path                            + pic.suggestFullFileName()));} catch (FileNotFoundException e) {                    e.printStackTrace();}            }        }        Document htmlDocument = wordToHtmlConverter.getDocument();ByteArrayOutputStream outStream = new ByteArrayOutputStream();DOMSource domSource = new DOMSource(htmlDocument);StreamResult streamResult = new StreamResult(outStream);TransformerFactory tf = TransformerFactory.newInstance();Transformer serializer = tf.newTransformer();serializer.setOutputProperty(OutputKeys.ENCODING, "utf-8");serializer.setOutputProperty(OutputKeys.INDENT, "yes");serializer.setOutputProperty(OutputKeys.METHOD, "html");serializer.transform(domSource, streamResult);outStream.close();String content = new String(outStream.toByteArray());FileUtils.write(new File(path, "1.html"), content, "utf-8");}}

html转word：

public void htmlToWord2() throws Exception {    InputStream bodyIs = new FileInputStream("f:\\1.html");InputStream cssIs = new FileInputStream("f:\\1.css");String body = this.getContent(bodyIs);String css = this.getContent(cssIs);//拼一个标准的HTML格式文档String content = "<html><head><style>" + css + "</style></head><body>" + body + "</body></html>";InputStream is = new ByteArrayInputStream(content.getBytes("GBK"));OutputStream os = new FileOutputStream("f:\\1.doc");    this.inputStreamToWord(is, os);}/** * 把is写入到对应的word输出流os中 * 不考虑异常的捕获，直接抛出 * @param is* @param os* @throws IOException */private void inputStreamToWord(InputStream is, OutputStream os) throws IOException {    POIFSFileSystem fs = new POIFSFileSystem();//对应于org.apache.poi.hdf.extractor.WordDocumentfs.createDocument(is, "WordDocument");fs.writeFilesystem(os);os.close();is.close();}/** * 把输入流里面的内容以UTF-8编码当文本取出。 * 不考虑异常，直接抛出 * @param ises* @return* @throws IOException */private String getContent(InputStream... ises) throws IOException {    if (ises != null) {        StringBuilder result = new StringBuilder();BufferedReader br;String line;        for (InputStream is : ises) {            br = new BufferedReader(new InputStreamReader(is, "UTF-8"));            while ((line=br.readLine()) != null) {                result.append(line);}        }        return result.toString();}    return null;}
