前端套了ruoyi，使用com.jfinal.cos 2020.4正常，升级为2022.2。会在cotroller使用getFile（）时，调用Cotroller.class 的 new MultipartRequest强制转换报错：
Caused by: java.lang.NoSuchMethodError: com.oreilly.servlet.MultipartRequest.<init>(Ljavax/servlet/http/HttpServletRequest;Ljava/lang/String;ILjava/lang/String;Lcom/oreilly/servlet/multipart/FileRenamePolicy;)V

自定义UploadController.java
uploadFile = getFile("file", UploadService.uploadTempPath, UploadService.imageMaxSize);Cotroller.class：
List<UploadFile> () {
(!(.MultipartRequest)) {
.= MultipartRequest(.)}
((MultipartRequest).).getFiles()}前端js
(fileobj) {
data = ()data.(file)data.()data.().({
