aspose pdf 转成html,利用Aspose将office转换成HTML、PDF格式

一、重要转换代码：

@Override

public void transform(InputStream in, OutputStream out, String fileName) throws IOException {

UUID uuid = UUID.randomUUID();

this.cacheFileName = fileName.substring(0, fileName.lastIndexOf(".")) + "-" + uuid;

// 设置本地缓存的路径

String tmpPath = localHtmlCachePath + IOUtils.DIR_SEPARATOR + this.cacheFileName + ".pdf";

String lowerFileName = fileName.toLowerCase();

try {

if (!new File(tmpPath).exists()) {

if (lowerFileName.endsWith(".xls") || lowerFileName.endsWith(".xlsx")

|| lowerFileName.endsWith(".csv")) {

com.aspose.cells.Workbook workbook = new com.aspose.cells.Workbook(in);

workbook.save(tmpPath, com.aspose.cells.SaveFormat.PDF);

} else if (lowerFileName.endsWith(".doc") || lowerFileName.endsWith(".docx")

|| lowerFileName.endsWith(".rtf")) {

com.aspose.words.Document doc = new com.aspose.words.Document(in);

doc.save(tmpPath, com.aspose.words.SaveFormat.PDF);

} else if (lowerFileName.endsWith(".ppt") || lowerFileName.endsWith(".pptx")

|| lowerFileName.endsWith(".pps") || lowerFileName.endsWith(".ppsx")) {

com.aspose.slides.Presentation ppt = new com.aspose.slides.Presentation(in);

ppt.save(tmpPath, com.aspose.slides.SaveFormat.Pdf);

} else if (lowerFileName.endsWith(".vdx") || lowerFileName.endsWith(".vsx")

|| lowerFileName.endsWith(".vtx") || lowerFileName.endsWith(".vsd")

|| lowerFileName.endsWith(".vsdx")) {

com.aspose.diagram.Diagram visio = new com.aspose.diagram.Diagram(in);

visio.save(tmpPath, com.aspose.diagram.SaveFileFormat.PDF);

} else if (lowerFileName.endsWith(".pdf")) {

com.aspose.pdf.Document pdf = new com.aspose.pdf.Document(in);

pdf.save(tmpPath, com.aspose.pdf.SaveFormat.Pdf);

}

}

if (out instanceof ResponseOutputStream) {

HttpServletResponse response = ((ResponseOutputStream) out).getResponse();

response.sendRedirect("/filePreview/officeHtmlFileViwer/" + this.cacheFileName + ".pdf");

}

} catch (Exception ex) {

throw new RuntimeException(ex);

}

}

二、创建了一个maven 项目，用到的相关jar如下：

三、遇到问题：

1、缓存文件夹不存在则创建：

// 文件夹不存在则创建

if (!new File(localHtmlCachePath).exists()) {

new File(localHtmlCachePath).mkdirs();

}

2、有水印：获取lic有问题：不能图省事，要以此次的获取InputStream(setLicense方法执行完可能是把InputStream给close了)

3、response.sendRedirect("/preview/officeHtmlFileViwer/" + this.cacheFileName + ".html");执行之后没有打开新页面

原因：不能close，因为还有请求在跑。
