Wanted to test a post request in POSTMAN.
public enum TimeUnit {
HOURS("hours"),
MINUTE("mins");
private String value;
public static TimeUnit get(String text) {
return Arrays.stream(TimeUnit.values())
.filter(a -> Objects.equals(a.getValue(), text))
.findFirst()
.orElse(null);
}
}
public final class SchoolTimeTable {
private Double value;
private TimeUnit unit;
public SchoolTimeTable (double value, TimeUnit unit) {
this.value = value;
this.unit=unit;
}
}
public class SchoolDto {
private String name;
private String address;
private MultipartFile profileImage;
private MultipartFile[] galleryImages;
private SchoolTimeTable openCloseTime;
}
Spring MVC Controller
@PostMapping(value = "/schoolInfo", produces = { MediaType.APPLICATION_JSON_VALUE })
public ResponseEntity<Object> saveSchoolInfo( @Parameter(required = true, schema = @Schema(implementation = SchoolDto.class)) SchoolDto schoolDto) throws IOException, InterruptedException {
...
}
I want to send SchoolDto (POSTMAN: body->raw->json) in post request to get desired result. But I am not able to create the json which supports SchoolTimeTable (Object) and MultipartFile types. I don’t even know whether it is possible with JSON or not. Note: Same could be achieved using body->form-data with key/value.
Please help.

Answer
I think you should not upload files within a application/json request, to do so you should use a multipart/form-data request. Your request may have three parts profileImage, galleryImages and schoolInfo.
Remove profileImage and galleryImages from SchoolDto class
Modify your method signature to support the multipart request
@PostMapping(value = "/schoolInfo", consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
public ResponseEntity<Object> saveSchoolInfo(@RequestPart(value = "profileImage") MultipartFile profileImage, @RequestPart(value = "galleryImages") MultipartFile[] galleryImages, @RequestPart(value = "schoolInfo") SchoolDto schoolInfo) throws IOException, InterruptedException {
...
}
In addtion you can implement a @SpringBootTest unit test using RestDocumentationExtension to check whether your code works and to produce a curl request sample that will help you to understand how to make a request to your endpoint
