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

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
