java利⽤第三⽅jar实现excel,word,ppt,txt转pdf格式如果遇到利⽤aspose 把excel转pdf遇到复杂⽂件被拆分成多页的情况，添加如下代码：
PdfSaveOptions pOptions = new PdfSaveOptions();
pOptions.setAllColumnsInOnePagePerSheet(true);
excel.save(destFilePath,pOptions);
⽂件上传代码：
public String fileUpload(HttpServletRequest request, HttpServletResponse response) {
String saveDirectory = ServletContext().getRealPath("/upload");//上传路径
// 将当前上下⽂初始化给 CommonsMutipartResolver （多部分解析器）
CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver(
if (multipartResolver.isMultipart(request)) {
// 将request变成多部分request
MultipartHttpServletRequest multiRequest = (MultipartHttpServletRequest) request;
// 获取multiRequest 中所有的⽂件名
Iterator iter = FileNames();
String extName = "";// 扩展名
while (iter.hasNext()) {
// ⼀次遍历所有⽂件
MultipartFile file = ().toString());
if (file != null) {
try {
InputStream is = InputStream();
//获取⽂件md5值判断是否有重复，如果有⽂件就不上传，直接读取
String fileHashCode = MD5Util.md5HashCode32(is);
String originalFileName = OriginalFilename();
//获取扩展名
extName = originalFileName.substring(originalFileName.lastIndexOf("."));
//源⽂件上传地址
String sourceFilePath = saveDirectory + File.separator + fileHashCode + extName;
//⽣成的⽬标⽂件地址
String destinatFilePath = RealPath("/convert")+File.separator+fileHashCode + ".pdf";
// 表⽰⽂件已存在不需要上传
if (new File(sourceFilePath).exists()) {
continue;//跳出本次循环
} else {
// ⽂件转换⼯具⽤于转换⽂件，最好新开线程，对⽂件较⼤的需要等待时间。参数（源⽂件路径，⽬标⽂件路径） vert(sourceFilePath, destinatFilePath);
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
return "请选择⽂件上传！";
}
return "⽂件上传请求配置错误！";
}
定义函数⽤于判断调⽤哪个转换函数：
public class FileConvertUtils {
public static final Logger log = Logger(FileConvertUtils.class);
public static void convert(final String sourceFilePath ,final String destFilePath){
String fileType = sourceFilePath.substring(sourceFilePath.lastIndexOf("."));
ExecutorService executor = wCachedThreadPool() ;
executor.submit(() -> {
try {
//要执⾏的业务代码，
if(!"".equals(fileType)&&fileType!=null){
if(".doc".equals(fileType)||".docx".equals(fileType)||".wps".equals(fileType)){
OfficeToPdfUtils.word2Pdf(sourceFilePath,destFilePath);
}else if(".txt".equals(fileType)){
OfficeToPdfUtils.word2Pdf(sourceFilePath,destFilePath);
}else if(".xls".equals(fileType)||".xlsx".equals(fileType)){
}else if(".ppt".equals(fileType)||".pptx".equals(fileType)){
OfficeToPdfUtils.ppt2Pdf(sourceFilePath,destFilePath);
}else if(".pdf".equals(fileType)){
}
}
}catch(Exception e) {
e.printStackTrace();
throw new RuntimeException("报错啦！！");
}
});
}
}
