org.apache.catalina.connector.RequestFacade问题
org.apache.catalina.connector.RequestFacade cannot be cast to org.springframework.web.multipart.MultipartHttpServletRequest
这个错误怎么解决~
代码如下：
     public String uploadfile(Map<String, Object> modelMap,
HttpServletRequest request, String documentDetails,String documentUploadingMan,
PlatformDocunment platformDocunment,String documentRemark) throws IOException {

MultipartHttpServletRequest multipart = (MultipartHttpServletRequest) request;
MultipartFile file = multipart.getFile("file");

FileUtilImpl fileUpUtil = new FileUtilImpl();
String ext = fileUpUtil.getFileExt(file);
String outFileName = System.currentTimeMillis() + ext;
String dirFile = request.getSession().getServletContext()
.getRealPath("/resource/code/document");//code后加不加/都可以的
// URL relativepath = request.getSession().getServletContext()
// .getResource("/resource/code");

// String relativepathString = relativepath.getFile();
// String relativepathString2 = relativepath.getPath();

fileUpUtil
.upLoadFile(file.getInputStream(), dirFile, outFileName, null);


platformDocunment.setDocumentName(outFileName);
platformDocunment.setDocumentDetails(documentDetails);



platformDocunment.setDocumentUploadingTime(new Timestamp(System
.currentTimeMillis()));
platformDocunment.setDocumentUploadingMan(documentUploadingMan);
platformDocunment.setDocunmentStoreAddress("/resource/code/document/");
platformDocunment.setDocumentRemark(documentRemark);

Transaction transaction = platformImageDAO.getSession()
.beginTransaction();
platformDocunmentDAO.save(platformDocunment);


transaction.commit();

return "manager/success";
    }
}
------最佳解决方案--------------------
是类型转换错误，怎么解决我也不太清楚奥

谢谢了，解决了，这个上传不需要经过后台，提交完成后，才经过后台，直接把页面提交就可以了，O(∩_∩)O~
