Implement fileUploadGet, fileUploadPost, and fileDeletion (names tbd/discussed)

What is working so far in preliminary tests for dummy get and post feedback from the server, There needs to be some handling of error states as well probably:

@MethodAccessible
@RequestMapping(method = RequestMethod.GET, params = "methodToCall=fileUpload")
public @ResponseBody Map fileUploadGet(@ModelAttribute("KualiForm") UifFormBase form, BindingResult result,
HttpServletRequest request, HttpServletResponse response)

{ List<FileBase> returnObjects = new ArrayList<FileBase>(); // TODO get the files from service/db here and iterate (unique key would id of top level object + property) // fake data for testing FileBase fakeFile = new FileBase(); fakeFile.setName("fakeName.png"); fakeFile.setSize(5000000L); fakeFile.setDeleteUrl("?methodToCall=fileDelete"); returnObjects.add(fakeFile); Map<String, Object> files = new HashMap<String, Object>(); // TODO actual version would use a name passed to the request files.put("files", returnObjects); return files; }

@MethodAccessible
@RequestMapping(method = RequestMethod.POST, params = "methodToCall=fileUpload")
public @ResponseBody Map fileUploadPost(@ModelAttribute("KualiForm") UifFormBase uifForm, BindingResult result,
MultipartHttpServletRequest request, HttpServletResponse response) {
// TODO actual version would use a name passed to the request
List<MultipartFile> uploadedFiles = request.getFiles("files");

List<FileBase> returnObjects = new ArrayList<FileBase>();

for (MultipartFile uploadedFile: uploadedFiles)

{ FileBase fileObject = new FileBase(uploadedFile); String id = UUID.randomUUID().toString() + "_" + uploadedFile.getName(); // TODO Saving to a db/file system would go here // TODO Generation and setting of thumbnail url (when applicable) and file url would go here fileObject.setId(id); fileObject.setDeleteType("DELETE"); // TODO Form key, cache key, view id needs to be added here (probably) fileObject.setDeleteUrl("?methodToCall=fileDelete"); returnObjects.add(fileObject); }

ObjectPropertyUtils.setPropertyValue(uifForm, "files", returnObjects);

Map<String, Object> files = new HashMap<String, Object>();
// TODO actual version would use a name passed to the request
files.put("files", returnObjects);
return files;
}
