I am trying to upload an audio file using the following code on server.Right now, it works perfectly well for image files but not for audios.I think MultipartFile should work with audio files as well.Can any one tell me what is wrong here?
I am getting "The server refused this request because the request entity is in a format not supported by the requested resource for the requested method." error.
Does MultipartFile not work with audio files?If no what is an alternative?
#Transactional
public BaseVO uploadImage(MultipartFile file, long userId){
Map<String, Object> alertParams = new HashMap<String, Object>();
try{
if (!file.isEmpty()) {
Image profileImage = imageRepository.findByUserId(userId);
if(profileImage == null){
profileImage = new Image();
profileImage.setUserId(userId);
}
File dir = null;
String realPath;
if(liveBuild == "true"){
realPath = liveImageUploadRepository;
dir = new File(realPath);
}else{
HttpServletRequest request = ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getRequest();
realPath = request.getSession().getServletContext().getRealPath("/") + devImageUploadRepository;
dir = new File(realPath);
}
if (!dir.exists()) {
dir.mkdirs();
}
String finalFileStorePath = realPath + "/" + userId + ".jpg";
File path = new File(finalFileStorePath);
file.transferTo(path);
profileImage.setImagePath(realPath);
//profileImage.setImageName(userId + ".jpg");
profileImage.setImageName(userId+"");
profileImage.setImageType(".jpg");

alertParams.put("id", profileImage.getId());

This is re-worded from a previous question (which was probably a bit unclear).
I want to download a text file via FTP from a remote server, read the contents of the text file into a string and then discard the file. I don't need to actually save the file.
I am using the Apache Commons library so I have:
import org.apache.commons.net.ftp.FTPClient;
Can anyone help please, without simply redirecting me to a page with lots of possible answers on?
Not going to do the work for you, but once you have your connection established, you can call retrieveFile and pass it an OutputStream. You can google around and find the rest...
FTPClient ftp = new FTPClient();
...
ByteArrayOutputStream myVar = new ByteArrayOutputStream();
ftp.retrieveFile("remoteFileName.txt", myVar);
ByteArrayOutputStream
retrieveFile
Normally I'd leave a comment asking 'What have you tried?'. But now I'm feeling more generous :-)
Here you go:
private void ftpDownload() {
FTPClient ftp = null;
try {
ftp = new FTPClient();
ftp.connect(mServer);
try {
int reply = ftp.getReplyCode();
if (!FTPReply.isPositiveCompletion(reply)) {
throw new Exception("Connect failed: " + ftp.getReplyString());
}
if (!ftp.login(mUser, mPassword)) {
throw new Exception("Login failed: " + ftp.getReplyString());
}
try {
ftp.enterLocalPassiveMode();
if (!ftp.setFileType(FTP.BINARY_FILE_TYPE)) {
Log.e(TAG, "Setting binary file type failed.");
}
transferFile(ftp);
} catch(Exception e) {
handleThrowable(e);
} finally {
if (!ftp.logout()) {
Log.e(TAG, "Logout failed.");
}
}
} catch(Exception e) {
handleThrowable(e);
} finally {
ftp.disconnect();
}
} catch(Exception e) {
handleThrowable(e);
}
}
private void transferFile(FTPClient ftp) throws Exception {
long fileSize = getFileSize(ftp, mFilePath);
InputStream is = retrieveFileStream(ftp, mFilePath);
downloadFile(is, buffer, fileSize);
is.close();
if (!ftp.completePendingCommand()) {
throw new Exception("Pending command failed: " + ftp.getReplyString());
}
}
private InputStream retrieveFileStream(FTPClient ftp, String filePath)
throws Exception {
InputStream is = ftp.retrieveFileStream(filePath);
int reply = ftp.getReplyCode();
if (is == null
|| (!FTPReply.isPositivePreliminary(reply)
&& !FTPReply.isPositiveCompletion(reply))) {
throw new Exception(ftp.getReplyString());
}
return is;
}
private byte[] downloadFile(InputStream is, long fileSize)
throws Exception {
byte[] buffer = new byte[fileSize];
if (is.read(buffer, 0, buffer.length)) == -1) {
return null;
}
return buffer; // <-- Here is your file's contents !!!
}
private long getFileSize(FTPClient ftp, String filePath) throws Exception {
long fileSize = 0;
FTPFile[] files = ftp.listFiles(filePath);
if (files.length == 1 && files[0].isFile()) {
fileSize = files[0].getSize();
}
Log.i(TAG, "File size = " + fileSize);
return fileSize;
}
You can just skip the download to local filesystem part and do:
FTPClient ftpClient = new FTPClient();
try {
ftpClient.connect(server, port);
ftpClient.login(user, pass);
ftpClient.enterLocalPassiveMode();
ftpClient.setFileType(FTP.BINARY_FILE_TYPE);
InputStream inputStream = ftpClient.retrieveFileStream("/folder/file.dat");
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream, "Cp1252"));
while(reader.ready()) {
System.out.println(reader.readLine()); // Or whatever
}
inputStream.close();
} catch (IOException ex) {
ex.printStackTrace();
} finally {
try {
if (ftpClient.isConnected()) {
ftpClient.logout();
ftpClient.disconnect();
}
} catch (IOException ex) {
ex.printStackTrace();
}
}
I've done uploading and displaying images with Vuetify and Spring.
It's work, but I'm not sure that I did it correctly. I am not sure that I have implemented the correct approach to solving this problem. Can you check it and say what you think?
On side Vuetify I use v-file-input component and axios for sending image to the server:
<v-file-input
v-model="selectedLogo"
accept="image/png, image/jpeg, image/bmp"
placeholder="Выберите Логотип"
prepend-icon="mdi-camera"
label="Логотип"
show-size
>
<template v-slot:append-outer>
<v-btn small #click="uploadLogo">
<v-icon dense>mdi-upload</v-icon>
</v-btn>
</template>
</v-file-input>
//...
uploadLogo(){
uploadLogo(this.$axios, this.company.id, this.selectedLogo)
}
//...
export const uploadLogo = function ($axios, id, logo) {
let formData = new FormData()
formData.append("logo", logo)
return $axios.post(url+ `/${id}/logo`,
formData,
{
headers: {
'Content-Type': 'multipart/form-data'
}
})
}
In Spring I have RestController:
#RestController
#RequestMapping("/api/")
public class FileController {
#Autowired
private FileStorageService fileStorageService;
#PostMapping("companies/{id}/logo")
public ResponseEntity<Object> uploadFile(#PathVariable Long id, #RequestParam("logo") MultipartFile logo) {
String fileName = fileStorageService.uploadLogo(id, logo);
return new ResponseEntity<>(HttpStatus.OK);
}
#GetMapping("/companies/{id}/logo")
public ResponseEntity<Resource> downloadLogo(#PathVariable Long id, HttpServletRequest request) {
Resource resource = fileStorageService.loadLogoAsResource(id);
String contentType = null;
try {
contentType = request.getServletContext().getMimeType(resource.getFile().getAbsolutePath());
} catch (IOException ex) {
contentType = "application/octet-stream";
}
return ResponseEntity.ok()
.contentType(MediaType.parseMediaType(contentType))
.header(HttpHeaders.CONTENT_DISPOSITION, "attachment; filename=\"" + resource.getFilename() + "\"")
.body(resource);
}
}
fileStorageService:
#Service
public class FileStorageService {
private final Path logoStorageLocation;
#Autowired
public FileStorageService(FileStorageProperties fileStorageProperties) {
this.logoStorageLocation = Paths.get(fileStorageProperties.getLogoDir())
.toAbsolutePath().normalize();
try {
Files.createDirectories(this.logoStorageLocation);
} catch (Exception ex) {
throw new FileStorageException("Could not create the directory where the uploaded files will be stored.", ex);
}
}
public String uploadLogo(Long id, MultipartFile file) {
String fileExtension = StringUtils.getFilenameExtension(file.getOriginalFilename());
String fileName = id.toString() + "." + fileExtension;
try {
if(fileName.contains("..")) {
throw new FileStorageException("Sorry! Filename contains invalid path sequence " + fileName);
}
Path targetLocation = this.logoStorageLocation.resolve(fileName);
Files.copy(file.getInputStream(), targetLocation, StandardCopyOption.REPLACE_EXISTING);
return fileName;
} catch (IOException ex) {
throw new FileStorageException("Could not store file " + fileName + ". Please try again!", ex);
}
}
public Resource loadLogoAsResource(Long id) {
String fileName = id.toString() + ".png";
try {
Path filePath = this.logoStorageLocation.resolve(fileName).normalize();
Resource resource = new UrlResource(filePath.toUri());
if(resource.exists()) {
return resource;
} else {
throw new FileNotFoundException("File not found " + fileName);
}
} catch (MalformedURLException ex) {
throw new FileNotFoundException("File not found " + fileName, ex);
}
}
}
My idea is uploading/displaying images by URL http://server/api/companies/{id}/logo without knowing the name of the logo file.
For displaying I use v-img component:
<v-img :src="'http://localhost:8081/api/companies/' + company.id +'/logo'"></v-img>
Questions:
What do you think about my solution?
Here I use RestController for displaying images.
I thought that I can get image directly by its location on the server. Without using RestController for #GetMapping. For example, if my images are stored in the folder with path /images/companies/logo on the server, I can get my images by URL with path http://server/images/companies/logo/namelogo.png
In this way, I should know name of the file on the server.
How can I display the image without using RestController for #GetMapping?
I use spring mvc I want to uplaod image to jsp form so I add enctype="multipart/form-data" to the form tag but when i add this, modelAttribute values equals null in the controller
This is my form in jsp page:
<form:form action="saveContact" method="post" modelAttribute="Contacting" id="container" enctype="multipart/form-data">
This is the header of the function in controller:
#RequestMapping(value = "/saveContact", method = RequestMethod.POST)
public ModelAndView saveContact(#ModelAttribute ("Contacting") Contacting Contacting,ModelAndView modelndView,HttpServletRequest request ,HttpServletResponse response
) throws Exception {............}
#ModelAttribute ("Contacting") Contacting Contacting all values are null. and When I erease the enctype="multipart/form-data" from form tag its work well but I cant upload the image
this is the uplaud function:
public void uplaodImages(String url,HttpServletRequest request) {
// configures upload settings
DiskFileItemFactory factory = new DiskFileItemFactory();

String uuidValue = "";
FileItem itemFile = null;
try {
// parses the request's content to extract file data
List formItems = upload.parseRequest(request);
Iterator iter = formItems.iterator();
// iterates over form's fields to get UUID Value
while (iter.hasNext()) {
FileItem item = (FileItem) iter.next();
if (item.isFormField()) {
if (item.getFieldName().equalsIgnoreCase(UUID_STRING)) {
uuidValue = item.getString();
}
}
// processes only fields that are not form fields
if (!item.isFormField()) {
itemFile = item;

String keyName = uuidValue + '.' + ext;

TransferManager tm = new TransferManager(new ProfileCredentialsProvider());
System.out.println("Hello");
// TransferManager processes all transfers asynchronously,
// so this call will return immediately.
Upload upload1 = tm.upload(
S3_BUCKET_NAME, url, itemFile.getInputStream(),om);
System.out.println("Hello2");
try {
// Or you can block and wait for the upload to finish
upload1.waitForCompletion();
System.out.println("Upload complete.");
} catch (AmazonClientException amazonClientException) {

amazonClientException.printStackTrace();

I only receive the GPS, Report and LOG data every time. The other 2 files I only receive ONE... Im sending them exactly the same way, but I'm receiving only one of them.
Does anyone detects the error on my code???
EDIT
I just discovered that if the smartwatch is connected to the handheld at the time that the files are sent, they are all received. If they are not connected, one of the files (RightDevice.txt or LeftDevice.txt) are not received when they connect...
I solved it!
It was the most basic error of all.... I was sending the same path for the two files (RightDevice and LeftDevice) so only one of the objects was updated on the googleapiclient.
I just wanna ask if it is possible to use my customize toast in onPostExecute of my Asyntask in android. If yes then how? I tried to put it on the onPostExecute but I got a lot red lines. Here is my code for my customize toast:
Typeface tfR= Typeface.createFromAsset(getAssets(), "Gothic_Regular.TTF");
LayoutInflater inflater = getLayoutInflater();
View layouttoast = inflater.inflate(R.layout.toast_bg, (ViewGroup)findViewById(R.id.toastAttribute));
TextView msg = ((TextView) layouttoast.findViewById(R.id.txt_toast));
msg.setTypeface(tfR);
msg.setText(toast_msg);
msg.setTextSize(TypedValue.COMPLEX_UNIT_PX,16);
Toast mytoast = new Toast(getBaseContext());
mytoast.setView(layouttoast);
mytoast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);
mytoast.setDuration(Toast.LENGTH_SHORT);
mytoast.show();
Then I want to put it here:

I think I've found out what's going on. Your scope is wrong. currently your code is running in AsyncTask, not Activity! That's why you cannot use getAssets, getLayoutInflater, findViewById, getBaseContext. Create your AsyncTask in your xxxActivity. And use Your xxxActivity.this.findViewById, and so on.
