below is the android part
new MultipartUploadRequest(this,uploadid,UPLOAD_URL)
.addFileToUpload(path,"image")
.addParameter("name",name)
.setNotificationConfig(new UploadNotificationConfig())
.setMaxRetries(2)
.startUpload();
below is my java controller in web services
#RequestMapping(value = "/uploadm",method=RequestMethod.POST)
public void submitQuestionuploading(#RequestBody String image) throws Exception
{
System.out.println(1+""+image);
try {
byte[] bytes = image.getBytes();
System.out.println(11);
BufferedOutputStream stream =new BufferedOutputStream(new
FileOutputStream(new File(UPLOAD_DIRECTORY +"11.png")));
stream.write(bytes);
stream.flush();
stream.close();
}
catch (Exception e) {
System.out.println(e);
}
output is this one i got in console but file is created but it is corrupted and it s size 0bytes ,
---------AndroidUploadService1518510071115 Content-Disposition: form-data; name="image"; filename="IMG_20180211_000033.jpg"
Content-Type: image/jpeg
ÿØÿá3ØExif
i tried to put this in java controller but it is not working
#RequestMapping(value = "/upload", method = RequestMethod.POST ,
headers = "Content-Type=multipart/form-data") public String
fileUpload(#RequestParam("image") CommonsMultipartFile file) {}
but i want to do in spring MVC only, help me to take uploaded file
This is a working file uploader
#ResponseStatus(code = HttpStatus.CREATED)
#RequestMapping(value = "asset", method = RequestMethod.POST, consumes = {
MediaType.MULTIPART_FORM_DATA_VALUE}, produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
#ResponseBody
public String uploadImage(
#RequestParam("image") MultipartFile file) {
byte[] bytes = file.getBytes();
//do something with byte
return "ok or anything you want to return";
}
And also you need to register MultipartResolver as a depandency.
#Bean(name = "multipartResolver")
public CommonsMultipartResolver multipartResolver() {
CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
multipartResolver.setMaxUploadSize(100000);
return multipartResolver;
}
you can deploy this code and then test using postman.
there are various tutorials for this.
you may have a look at

Good afternoon.
I need to download an rtf file that was put into the database as a byte[] to the user. The application runs on the server, and it coulnd be unloaded on the client's PC. I took methods from my previous project. There it was necessary to form and unload the exel file. I tried to upgrade them for this task, but I ran into one problem.
Naturally, I can't get the MediaType for byte[].
Tell me, can I somehow explicitly specify it?
public class MediaTypeUtils {
public static MediaType getMediaTypeForFileName(ServletContext servletContext, String fileName) {
String mineType = servletContext.getMimeType(fileName);
try {
MediaType mediaType = MediaType.parseMediaType(mineType);
return mediaType;
} catch (Exception e) {
return MediaType.APPLICATION_OCTET_STREAM;
}
} }
public static ResponseEntity<InputStreamResource> downloadFile1(ServletContext servletContext, PaymentOrderArchive archive) throws IOException {
MediaType mediaType = MediaTypeUtils.getMediaTypeForFileName(servletContext, archive.getRtffilename());
InputStream resource = null;
try (FileOutputStream stream = new FileOutputStream(archive.getRtffilename())) {
stream.write(archive.getEfile());
IOUtils.copyLarge(resource, stream);
InputStreamResource file = new InputStreamResource(resource);
return ResponseEntity.ok()
// Content-Disposition
.header(HttpHeaders.CONTENT_DISPOSITION, "attachment;filename=" + archive.getRtffilename())
// Content-Type HERE
.contentType(mediaType)
// Contet-Length
.contentLength(resource.available()) //
.body(new InputStreamResource(resource));
}
}
My Controller use " org.apache.commons.fileupload " realized the file UPload.
see it:
#PostMapping("/upload")
public String upload2(HttpServletRequest request) throws Exception {
ServletFileUpload upload = new ServletFileUpload();
FileItemIterator iter = upload.getItemIterator(request);
boolean uploaded = false;
while (iter.hasNext() && !uploaded) {
FileItemStream item = iter.next();
if (item.isFormField()) {
item.openStream().close();
} else {
String fieldName = item.getFieldName();
if (!"file".equals(fieldName)) {
item.openStream().close();
} else {
InputStream stream = item.openStream();
// dosomething here.
uploaded = true;
}
}
}
if (uploaded) {
return "ok";
} else {
throw new BaseResponseException(HttpStatus.BAD_REQUEST, "400", "no file field or data file is empty.");
}
}
and my MockMvc code is
public void upload() throws Exception {
File file = new File("/Users/jianxiaowen/Documents/a.txt");
MockMultipartFile multipartFile = new MockMultipartFile("file", new FileInputStream(file));
HashMap<String, String> contentTypeParams = new HashMap<String, String>();
contentTypeParams.put("boundary", "----WebKitFormBoundaryaDEFKSFMY18ehkjt");
MediaType mediaType = new MediaType("multipart", "form-data", contentTypeParams);
MvcResult mvcResult = mockMvc.perform(MockMvcRequestBuilders.post(baseUrl+"/upload")
.content(multipartFile.getBytes())
.contentType(mediaType)
.header(Origin,OriginValue)
.cookie(cookie))
.andReturn();
logResult(mvcResult);
}
my controller is right , it has successed in my web project,
but I want to test it use MvcMock, it has some mistake, see :
can someOne can help me?
"status":"400","msg":"no file field or data file is empty.","data":null
I don't know why it says my file is empty.
my English is poor, thank you very much if someone can help me.
The MockMvc can be used for integration testing for controllers using Apache Commons Fileupload too!
Import the org.apache.httpcomponents:httpmime into your pom.xml or gradle.properties
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpmime</artifactId>
<version>4.5.13</version>
</dependency>
Update the code to use MultipartEntityBuilder to build the multipart request on the client, and then serialize the entity into bytes, which is then set in the request content
public void upload() throws Exception {
File file = new File("/Users/jianxiaowen/Documents/a.txt");
String boundary = "----WebKitFormBoundaryaDEFKSFMY18ehkjt";
// create 'Content-Type' header for multipart along with boundary
HashMap<String, String> contentTypeParams = new HashMap<String, String>();
contentTypeParams.put("boundary", boundary); // set boundary in the header
MediaType mediaType = new MediaType("multipart", "form-data", contentTypeParams);
// create a multipart entity builder, and add parts (file/form data)
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
HttpEntity multipartEntity = MultipartEntityBuilder.create()
.addPart("file", new FileBody(file, ContentType.create("text/plain"), file.getName())) // add file
// .addTextBody("param1", "value1") // optionally add form data
.setBoundary(boundary) // set boundary to be used
.build();
multipartEntity.writeTo(outputStream); // or getContent() to get content stream
byte[] content = outputStream.toByteArray(); // serialize the content to bytes
MvcResult mvcResult = mockMvc.perform(
MockMvcRequestBuilders.post(baseUrl + "/upload")
.contentType(mediaType)
.content(content) // finally set the content
.header(Origin,OriginValue)
.cookie(cookie)
).andReturn();
logResult(mvcResult);
}
Can you try the below?
mockMvc.perform(
MockMvcRequestBuilders.multipart(baseUrl+"/upload")
.file(multiPartFile)
).andReturn();
Update:
You need to update the controller to handle the MultipartFile:
#PostMapping("/upload")
public String upload2(#RequestParam(name="nameOfRequestParamWhichContainsFileData")
MultipartFile uploadedFile, HttpServletRequest request) throws Exception {
//the uploaded file gets copied to uploadedFile object.
}
You need not use another library for managing file uploads. You can use the file upload capabilities provided by Spring MVC.
I've written a typical spring boot application, now I want to add integration tests to that application.
I've got the following controller and test:
Controller:
#RestController
public class PictureController {
#RequestMapping(value = "/uploadpicture", method = RequestMethod.POST)
public ResponseEntity<VehicleRegistrationData> uploadPicturePost(#RequestPart("userId") String userId, #RequestPart("file") MultipartFile file) {
try {
return ResponseEntity.ok(sPicture.saveAndParsePicture(userId, file));
} catch (IOException e) {
logger.error(e.getMessage(), e);
}
return new ResponseEntity<>(HttpStatus.NOT_IMPLEMENTED);
}
}
Test:
#Test
public void authorizedGetRequest() throws Exception {
File data = ResourceUtils.getFile(testImageResource);
byte[] bytes = FileUtils.readFileToByteArray(data);
ObjectMapper objectMapper = new ObjectMapper();
MockMultipartFile file = new MockMultipartFile("file", "test.jpg", MediaType.IMAGE_JPEG_VALUE, bytes);
MockMultipartFile userId =
new MockMultipartFile("userId",
"userId",
MediaType.MULTIPART_FORM_DATA_VALUE,
objectMapper.writeValueAsString("123456").getBytes()
);
this.mockMvc.perform(multipart("/uploadPicture")
.file(userId)
.file(file)
.header(API_KEY_HEADER, API_KEY)).andExpect(status().isOk());
}
Testing the controller with the OkHttp3 client on android works seamlessly, but I can't figure out how to make that request work on the MockMvc
I expect 200 as a status code, but get 404 since, I guess, the format is not the correct one for that controller
What am I doing wrong?
It must be a typo.
In your controller, you claim the request URL to be /uploadpicture, but you visit /uploadPicture for unit test.
I'm using spring boot, I need to upload a multipart file (jpg or png file). I need to send a (POST request to upload the multi part file using "postman"), can anyone provide a screen shot of "postman" of how to set it up to do that or tell me? Thanks.
method :
#RequestMapping(method = RequestMethod.POST, value = "/upload")
#ResponseBody
ResponseEntity<?> writeUserProfilePhoto(#PathVariable Long user, #RequestPart("file") MultipartFile file) throws Throwable {
byte bytesForProfilePhoto[] = FileCopyUtils.copyToByteArray(file.getInputStream()); //Return an InputStream to read the contents of the file from.
this.crmService.writeUserProfilePhoto(user, MediaType.parseMediaType(file.getContentType()),bytesForProfilePhoto);
HttpHeaders httpHeaders = new HttpHeaders();
URI uriOfPhoto = ServletUriComponentsBuilder.fromCurrentContextPath()
.pathSegment(("/users" + "/{user}" + "/photo").substring(1))
.buildAndExpand(Collections.singletonMap("user", user)).toUri();
httpHeaders.setLocation(uriOfPhoto);
return new ResponseEntity<>(httpHeaders, HttpStatus.CREATED);
}
and this is how I sent the POST request:
my configuration class:
#Configuration
#ConditionalOnClass({ Servlet.class, StandardServletMultipartResolver.class, MultipartConfigElement.class })
#ConditionalOnProperty(prefix = "multipart", name = "enabled", matchIfMissing = true)
#EnableConfigurationProperties(MultipartProperties.class)
public class MultipartAutoConfiguration {
#Autowired
private MultipartProperties multipartProperties = new MultipartProperties();
#Bean
#ConditionalOnMissingBean
public MultipartConfigElement multipartConfigElement() {
return this.multipartProperties.createMultipartConfig();
}
#Bean(name = DispatcherServlet.MULTIPART_RESOLVER_BEAN_NAME)
#ConditionalOnMissingBean(MultipartResolver.class)
public StandardServletMultipartResolver multipartResolver() {
return new StandardServletMultipartResolver();
}
}
The error in postman says
Required MultipartFile parameter 'file' is not present
The method signature looks fine defining file parameter:
ResponseEntity<?> writeUserProfilePhoto(
#PathVariable Long user, #RequestPart("file") MultipartFile file)
throws Throwable
The issue is that when using postman, you're using dog1 as the name of this parameter. Change it to file to match the expected parameter name for the multipart file.
This approach worked for me.

Optional<User> user=userRepo.findById(id);
if(!user.isPresent()) {
throw new UserException(-5, "User does not exists");
}
UUID uuid=UUID.randomUUID();
String uniqueUserId=uuid.toString();
try {
Files.copy(file.getInputStream(), fileLocation.resolve(uniqueUserId), StandardCopyOption.REPLACE_EXISTING);
user.get().setProfilePic(uniqueUserId);
userRepo.save(user.get());
}catch (IOException e) {
e.printStackTrace();
// TODO: handle exception
}
return ResponseHelper.statusResponse(200, "Profile Pic Uploaded Successfully");
}
I need to return image in my Spring controller.
I try answer in this Spring MVC: How to return image in #ResponseBody? but it's not working
my code is like this
#RequestMapping(value = "cabang/photo", method = RequestMethod.GET)
#ResponseBody
public ResponseEntity<byte[]> getPhoto() throws IOException {
File imgPath = new File("D:\\test.jpg");
byte[] image = Files.readAllBytes(imgPath.toPath());
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.IMAGE_JPEG);
headers.setContentLength(image.length);
return new ResponseEntity<>(image, headers, HttpStatus.OK);
}
but when I access it in browser, it doesn't show anything (just no picture icon). But if I read the image byte array, it is not empty.
Do I miss anything in my code?
Your code looks ok. Make sure you added ByteArrayHttpMessageConverter to your application's list of http message converters.
Java Config :
#Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
ByteArrayHttpMessageConverter byteConverter = new ByteArrayHttpMessageConverter();
converters.add(byteConverter);
super.configureMessageConverters(converters);
}
