Uploading document from angularjs to springboot - angularjs

Question

Angularjs $http.post gives a 404 exception but all the other methods works fine with the same codes, i am trying to upload a file via spring boot
The same codes works fine in my other project i did about last year, and the same $http.post works when i send information without a file
service.js
function addCompanyDoc(file, id) {
var deferred = $q.defer();
var data = new FormData();
data.append('file', file);
var config = {
transformRequest: angular.identity,
transformResponse: angular.identity,
headers: {
'Content-Type': undefined
}
}
console.log('appService file ');
console.dir(file); //cheking if file is available
$http.post('http://localhost:8080/listed/welcome/company/doc/' + id,
data, config)
.then(function(response) {
deferred.resolve(response.data);
},
function(errResponse) {
alert(errResponse.data.errorMessage);
console.error('Error while uploading company doc', errResponse);
this.flag = 'failed';
deferred.reject(errResponse);
});
return deferred.promise;
}
spring boot
#RequestMapping("/welcome")
public class controllers{
#RequestMapping(value = "/company/doc/{id}", method =
RequestMethod.POST, consumes = {"multipart/form-data" })
#ResponseBody
public ResponseEntity<Void> saveCompanyDoc(#RequestParam("file")
MultipartFile file, #PathVariable final int id){
//....uploading to DB
}
}
angularjs sends a document to spring boot and spring uploads to the DB / sends to a folder.
Working fine :-) with angularjs 1.7 & spring boot 2.*

Answer 1

Thanks for all the comments the above code is correct,
I created a dummy table and controller to test the app.
And it gave the same 404 error and i recalled a few weeks back i added an "admin folder" to handle CMS and directed all the ROLES to the "folder" and it blocked all the users from doing data POSTING. SO i just had to fix my WebSecurityConfig class :-)
