众所周知，我们想要word预览，要么转成pdf、要么成html！
POI提供了execl、word的转换方式，但是内容复杂而且容易出错！并且转换的也不完整！
还有一种方式，是直接在Linux服务器上装openOfiice插件，这样只需写一些简单的代码就很容易就能转换！
但是今天介绍第三种方式，
aspose.cells aspose.words只要加入这两个包，就能转换，而且 代码非常简单，在Linux和windows上都能用，废话不多说，直接上代码
package aspose; import com.aspose.cells.*; import com.aspose.words.Document; import com.aspose.words.ExportHeadersFootersMode; import com.aspose.words.FontSettings; import woldpdf.FontProvider; import javax.crypto.Cipher; import java.io.*; /** * @ClassName wordPDF * @Description TODO * @Author zhurongfei * @Data 2020/6/22 9:45 * Version 1.0 **/ public class wordPDF { /** * 获取license许可凭证 * @return */ private static boolean getLicense() { boolean result = false; try { String licenseStr = "<License>\n" + " <Data>\n" + " <Products>\n" + " <Product>Aspose.Total for Java</Product>\n" + " <Product>Aspose.Words for Java</Product>\n" + " </Products>\n" + " <EditionType>Enterprise</EditionType>\n" + " <SubscriptionExpiry>20991231</SubscriptionExpiry>\n" + " <LicenseExpiry>20991231</LicenseExpiry>\n" + " <SerialNumber>8bfe198c-7f0c-4ef8-8ff0-acc3237bf0d7</SerialNumber>\n" + " </Data>\n" + " <Signature>0nRuwNEddXwLfXB7pw66G71MS93gW8mNzJ7vuh3Sf4VAEOBfpxtHLCotymv1PoeukxYe31K441Ivq0Pkvx1yZZG4O1KCv3Omdbs7uqzUB4xXHlOub4VsTODzDJ5MWHqlRCB1HHcGjlyT2sVGiovLt0Grvqw5+QXBuinoBY0suX0=</Signature>\n" + "</License>"; InputStream license = new ByteArrayInputStream(licenseStr.getBytes("UTF-8")); License asposeLic = new License(); asposeLic.setLicense(license); result = true; } catch (Exception e) { e.printStackTrace(); } return result; } /** * word文档 转换为 PDF * @param inPath 源文件 * @param outPath 目标文件 */ public static void doc2pdf(String inPath, String outPath) { //验证License，获取许可凭证 if (!getLicense()) { return; } try { //新建一个PDF文档 File file = new File(outPath); if(!file.exists()){ file.createNewFile(); } //新建一个IO输出流 FileOutputStream os = new FileOutputStream(file); //获取将要被转化的word文档 FileInputStream inputStream = new FileInputStream(new File(inPath)); Document doc = new Document(inputStream); // HtmlSaveOptions hso = new HtmlSaveOptions(); // hso.setExportRoundtripInformation(true); // String filePath = FontProvider.class.getClassLoader().getResource("simsunb.ttf").getFile(); // FontSettings.getDefaultInstance().setFontsFolder(filePath, false); // 全面支持DOC, DOCX,OOXML, RTF HTML,OpenDocument,PDF, EPUB, XPS,SWF 相互转换 doc.save(os, com.aspose.words.SaveFormat.PDF); os.close(); } catch (Exception e) { e.printStackTrace(); } } /// <summary> /// excel转pdf /// </summary> /// <param name="path">文件地址</param> /// <param name="newFilePath">转换后的文件地址</param> /// <returns></returns> public static void ExcelToPdf(String path, String newFilePath) throws Exception { //验证License，获取许可凭证 if (!getLicense()) { return; } // FTPClient ftpClient = new FTPClient(); Workbook wb = new Workbook(path);// 原始excel路径 HtmlSaveOptions options = new HtmlSaveOptions(); options.setExportDocumentProperties(false); options.setExportWorkbookProperties(false); options.setExportWorksheetProperties(false); options.setExportSimilarBorderStyle(true); options.setExportImagesAsBase64(false); options.setExcludeUnusedStyles(true); options.setExportHiddenWorksheet(false); options.setWidthScalable(false); options.setPresentationPreference(false); options.setHtmlCrossStringType(HtmlCrossType.CROSS_HIDE_RIGHT); FileOutputStream fileOS = new FileOutputStream(newFilePath); wb.calculateFormula(); wb.save(fileOS, options); fileOS.close(); } public static void main(String[] args) throws Exception { ExcelToPdf("C:\\Users\\98790\\Desktop\\a.xlsx", "C:\\Users\\98790\\Desktop\\a.html"); // doc2pdf("C:\\Users\\98790\\Desktop\\a.docx", "C:\\Users\\98790\\Desktop\\a.pdf"); } }不过我写execl只能转换简单的html，复杂的如有多个execl的sheet，就会报错，具体还不知道怎么搞，有兴趣的话可以讨论
