how to send data using Postman in example DTO ,mainly Multipart file data,Angular 4,7
data in Multipartfile in Example DTO
public class ExampleDTo {
private MultipartFile image;
private String name;
private String description;
}
Controller Mapping
@PostMapping()
public ResponseEntity<?> saveExample(@RequestParam("dtoAnduploadingFiles") ExampleDTo dtoAnduploadingFiles ) throws IOException {
}
One way to do this is to use multiple multiparts.
So for example if you use this controller:
@PostMapping
public void uploadFileWithData(
@RequestPart ExampleDTo request,
@RequestPart("file") final MultipartFile file){
...
}
note: ExampleDto should contain only fields of json payload, not MultipartFile
In Postman you should use then form-data and choose file which you want to upload and also file with json payload.
You can do it like a normal multipart Form from Postman but you need to update your Mapping Method.
@PostMapping("/upload-file-form")
public ResponseEntity<?> multiUploadFileModel(@ModelAttribute ExampleDTo model) {
try {
saveUploadedFile(model.getImage()); // Create method to save your file or just do it here
formRepo.save(mode.getName(),model.getDescription()); //Save as per requirement
} catch (IOException e) {
return new ResponseEntity<>(HttpStatus.BAD_REQUEST);
}
return new ResponseEntity("Successfully uploaded!", HttpStatus.OK);
}
For complete code example look here.
And then you can test it on postman like this:
