Spring Boot and jQuery file upload : Unsupported media type
I am trying to upload a csv file with spring boot 1.2.0 REST controller and jQuery ajax. When I send the post request, I keep getting 415:Unsupported Media type error. Here is my form:
<form id="upload_form">
<div id="message">
</div>
<br/>
<div class="row" id="upload-file-div" style="display: none">
<div class='col-sm-3'>
<label>Select File</label>
<input type="file" name="file">
</div>
<div class='col-sm-3'>
<input type="button" id="file-upload" class="btn btn-primary" value="Upload" onclick="uploadFile()"/>
</div>
</div>
</form>
Here is my method to upload file:
function uploadFile(){
var response = api.uploadCSV($("#upload_form"));
if(response.status === 'OK'){
$("#message").css('color', 'green');
}else{
$("#message").css('color', 'red');
}
$("#message").html(response.message);
}
Here is the actual jQuery POST:
upload: function (url, form, ignoreSuccess) {
var response = null;
if (!this.validate(form)) {
var array = form.serializeArray();
alert(array);
var formData = new FormData(form);
console.warn(formData);
$.ajax({
type: "POST",
url: API_PROXY + url,
data: formData,
cache: false,
contentType: false,
processData: false,
async: false,
beforeSend: function (request) {
if (api.getSession() !== null) {
request.setRequestHeader("Authorization", "Bearer " + api.getSession().bearer);
}
},
success: function () {}
}).done(function (msg) {
response = msg;
});
}
return response;
}
Following is my controller:
@RequestMapping(consumes = "multipart/form-data", method = RequestMethod.POST,
value = "/upload/twitter", produces = MediaType.APPLICATION_JSON_VALUE)
public Response<String> uploadCsv(CsvUploadModel form) {
//Code
}
I have both MultipartConfigElement and MultipartResolver annotated in my spring boot class. I am using spring boot 1.2.0. When I send the post request with PostMan (chrome extension), it works as expected. However, when I try the above jquery code, it keeps throwing unsupported media type error.
Following things I have tried:
Can anyone please help me with this? Thanks in advance.
You can append your file input in your formData ; the following changes needs to be made:
This:
<input type="file" name="file">
Should be:
<input type="file" name="file" id="file">
And in your ajax code, this:
var formData = new FormData(form);
console.warn(formData);
$.ajax({
type: "POST",
url: API_PROXY + url,
data: formData,
Should be:
var formData = new FormData();
formData.add("file",$('#file')[0].files)
$.ajax({
type: "POST",
url: API_PROXY + url,
data: formData,
Or:
var formData = new FormData(form[0]);
$.ajax({
type: "POST",
url: API_PROXY + url,
data: formData,
