Failed to parse multipart servlet request #34441
Description
I am uploading a file from Angular using Java 17 with Spring Boot 3.2 as backend.
I noticed that when I updated Spring 2.x.x it shows me a multipart error. I don't know if the implementation with Angular changed for this type of request. The code I use is the following:
Angular17:
UploadFile(id, file:File): Observable<any[]> {
url = 'http://localhost:8080/import/"+id+"';
const formData: FormData = new FormData();
formData.append('uploadFile', file, file.name);
var headers: HttpHeaders = new HttpHeaders();
headers = headers.set('Content-type', 'multipart/form-data');
this.http.combineHeaders(headers);
return this.http.post(url, formData, 'UploadFile');
}
Java17:
@RequestMapping(value = "/import", method = RequestMethod.POST)
public ResponseEntity<Object> FileUpload(@PathVariable(value = "id") String Id, @RequestParam("uploadFile") MultipartFile uploadFile)
throws IOException {
//Here is processing uploadFile.
}Error:
{errCode: 4000, errMsg: "Failed to parse multipart servlet request"} errCode : 4000 errMsg : "Failed to parse multipart servlet request"
The library imported is import org.springframework.web.multipart.MultipartFile;
But it's very confusing because even though I don't have the file reading implementation, just by receiving the file as @RequestParam, I get the error.
Is it possible that something has changed for the new versions of Spring with Angular?
Thank you!!
