Spring Boot + Angular file upload unable to upload same file twice

Question

Error under Network in chrome

{ timeStamp: ......, status: 400
  error: \'Bad Request\',
  message: \'Required request part \'file\' is not present\'
  path:         


        

Answer 1

Param annotation in your controller looks for a field called file.

Change selectFile to file will solve the problem.

formData.append("file", this.data);

Parameter name matters in this, it has to be same in both Java & Angular
