Android POI操作office文档


一、添加POI的依赖:

//由于使用Apache官网下的包导入使用过程经常出错,发现用xdocreport里的包可以使用
//解析XML用到
implementation 'com.fasterxml:aalto-xml:1.0.0'
//docx文件转html用到
implementation 'fr.opensagres.xdocreport:fr.opensagres.poi.xwpf.converter.xhtml:2.0.1'
//poi的相关包
implementation 'fr.opensagres.xdocreport:document:2.0.1'
//doc转html
implementation 'org.apache.poi:poi-scratchpad:3.15-beta2'

二、部分功能代码:(代码为参考网上别人写的)

a、doc转html:

public void doc2Html(String fileName, String outPutFile)
            throws TransformerException, IOException,
            ParserConfigurationException {

        HWPFDocument wordDocument = new HWPFDocument(new FileInputStream(fileName));
        WordToHtmlConverter wordToHtmlConverter = new WordToHtmlConverter(
                DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument());

        //设置图片路径
        wordToHtmlConverter.setPicturesManager(new PicturesManager() {
            @Override
            public String savePicture(byte[] content, PictureType pictureType, String suggestedName, float widthInches, float heightInches) {
                String name = docName.substring(0, docName.indexOf("."));
                return name + "/" + suggestedName;
            }
        });

        //保存图片
        List pics = wordDocument.getPicturesTable().getAllPictures();
        if (pics != null) {
            for (int i = 0; i < pics.size(); i++) {
                Picture pic = (Picture) pics.get(i);
                System.out.println(pic.suggestFullFileName());
                try {
                    String name = docName.substring(0, docName.indexOf("."));
                    pic.writeImageContent(new FileOutputStream(savePath + name + "/"
                            + pic.suggestFullFileName()));
                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                }
            }
        }
        wordToHtmlConverter.processDocument(wordDocument);
        Document htmlDocument = wordToHtmlConverter.getDocument();
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        DOMSource domSource = new DOMSource(htmlDocument);
        StreamResult streamResult = new StreamResult(out);

        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);
        out.close();
        //保存html文件
        writeFile(new String(out.toByteArray()), outPutFile);
    }

public void writeFile(String content, String path) {
        FileOutputStream fos = null;
        BufferedWriter bw = null;
        try {
            File file = new File(path);
            if (!file.exists()) {
                file.createNewFile();
            }
            fos = new FileOutputStream(file);
            bw = new BufferedWriter(new OutputStreamWriter(fos, "utf-8"));
            bw.write(content);
        } catch (FileNotFoundException fnfe) {
            fnfe.printStackTrace();
        } catch (IOException ioe) {
            ioe.printStackTrace();
        } finally {
            try {
                if (bw != null)
                    bw.close();
                if (fos != null)
                    fos.close();
            } catch (IOException ie) {
            }
        }
    }

b、docx转html:

 private void docx2Html(String fileName, String outPutFile) {
        try {
            XWPFDocument document = new XWPFDocument(new FileInputStream(fileName));
            XHTMLOptions options = XHTMLOptions.create().indent(4);
            // 导出图片
            String name = docName.substring(0, docName.indexOf("."));
            File imageFolder = new File(savePath + name + "/");
            options.setExtractor(new FileImageExtractor(imageFolder));
            // URI resolver
            options.URIResolver(new FileURIResolver(imageFolder));
            options.setIgnoreStylesIfUnused(true);
            options.setOmitHeaderFooterPages(true);
            File outFile = new File(outPutFile);
            outFile.getParentFile().mkdirs();
            OutputStream out = new FileOutputStream(outFile);
            XHTMLConverter.getInstance().convert(document, out, options);
            out.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

c、excel转html:

private void excel2Html(String fileName, String outPutFile) {
        InputStream is = null;
        String htmlExcel = null;
        try {
            File sourcefile = new File(fileName);
            is = new FileInputStream(sourcefile);
            Workbook wb = WorkbookFactory.create(is);
            if (wb instanceof XSSFWorkbook) {
                XSSFWorkbook xWb = (XSSFWorkbook) wb;
                htmlExcel = getExcelInfo(xWb, true);
            } else if (wb instanceof HSSFWorkbook) {
                HSSFWorkbook hWb = (HSSFWorkbook) wb;
                htmlExcel = getExcelInfo(hWb, true);
            }
            htmlExcel = "" + fileName + "
