Hello,
I already posted this question on stackoverflow, but nobody answered it
there
(https://stackoverflow.com/questions/53189770/can-not-upload-file-when-using-a-swagger-generated-spring-server).
So I hope that someone on the dedicated servers will be able to help me.
I want to implement a file readout function on my REST Service. Since I do
not know how to use spring myself, I use swagger to generate the server
code for me. Normally this works perfectly fine, but when I try to upload
files I get the following error:
{
"timestamp": "2018-11-07T12:27:43.119Z",
"status": 400,
"error": "Bad Request",
"exception":
"org.springframework.web.multipart.support.MissingServletRequestPartException",
"message": "Required request part 'file' is not present",
"path": "/requirements/import"
}
My yaml uses the following lines for the import function:
/requirements/import:
post:
consumes:
- multipart/form-data
description:
Returns all requirements contained in the submitted reqIf file.
parameters:
- name: reqIfFile
in: formData
type: file
description: The reqIf file that contains the requirements.
responses:
200:
description: An array of requirements.
schema:
type: array
items:
$ref: 'requirement'
The generated interface (with some added exceptions):
@javax.annotation.Generated(value =
"io.swagger.codegen.languages.SpringCodegen", date =
"2018-04-05T07:19:00.887Z")
@Api(value = "requirements", description = "the requirements API")
public interface RequirementsApi {
@ApiOperation(value = "", nickname = "requirementsImportPost", notes =
"Returns
all requirements contained in the submitted reqIf file.", response =
Requirement.class, responseContainer = "List", tags = {})
@ApiResponses(value = {
@ApiResponse(code = 200, message = "An array of requirements.",
response = Requirement.class, responseContainer = "List") })
@CrossOrigin(origins = "*")
@RequestMapping(value = "/requirements/import", produces = {
"application/json" }, consumes = {
"multipart/form-data" }, method = RequestMethod.POST)
ResponseEntity<List<Requirement>> requirementsImportPost(
@ApiParam(value = "file detail") @Valid @RequestPart("file")
MultipartFile reqIfFile)
throws IOException, ContinuumException;
}
The code that actually does the readout:
@javax.annotation.Generated(value =
"io.swagger.codegen.languages.SpringCodegen", date =
"2018-04-05T07:19:00.887Z")
@Controller
public class RequirementsApiController implements RequirementsApi {
@Override
public ResponseEntity<List<Requirement>> requirementsImportPost(
@ApiParam(value = "file detail") @Valid @RequestPart("file")
final MultipartFile reqIfFile)
throws IOException, ContinuumException {
InputStream fileStream = new BufferedInputStream(reqIfFile.
getInputStream());
List<Requirement> list = ReadReqIF.readReqIfFile(fileStream);
return new ResponseEntity<List<Requirement>>(list, HttpStatus.OK);
}
}
Can someone tell me where a possible error is?
