Swagger inflector + complex objects

Question

Im trying to build service using swagger inflector. But currenltl i encountered some problem, when im trying to post complex object to my swagger controller. Please take a look on my configuration provided bellow.

My swagger.yaml:

swagger: "2.0" info: version: 1.0.0 title: Dummy Controller basePath: /v1 tags: - name: Dummy Controller description: Dummy controller schemes: - http paths: /someService/create: post: tags: - someService summary: Test description: "" operationId: createPoint consumes: - application/json - application/xml produces: - application/xml - application/json parameters: - in: body name: body description: Created object required: false schema: $ref: '#/definitions/Point' responses: default: description: successful operation definitions: Point: title: Point description: '' type: object properties: latitude: description: '' type: string longitude: description: '' type: string required: - latitude - longitude ApiResponse: properties: code: type: integer format: int32 type: type: string message: type: string xml: name: "##default"

My controller:

public class SomeServiceController { public ResponseContext createPoint(RequestContext request, Point point){ System.out.println(point); return new ResponseContext() .status(Status.OK); } }

When im trying to make post like this:

POST http://localhost:8080/v1/someService/create { "latitude":"10", "longitude":"20" }

Im getting

11:36:51.814 [qtp931940545-13] ERROR i.s.i.c.SwaggerOperationController - failed to invoke method public io.swagger.inflector.models.ResponseContext com.swagger.test.SomeServiceController.createPoint(io.swagger.inflector.models.RequestContext,com.swagger.test.model.Point) java.lang.IllegalArgumentException: argument type mismatch

My dependencies:

<dependencies> <dependency> <groupId>io.swagger</groupId> <artifactId>swagger-inflector</artifactId> <version>1.0.2</version> </dependency> <dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-frontend-jaxrs</artifactId> <version>3.1.1</version> </dependency> </dependencies>

Please help! What i have missed?

Did you add the Content-Type: application/json header to your request? — Helen

@Helen Yes, ive tried both json and xml (for xml structure) content types.. — Olekso

As i found later, the object which comes to controller is ObjectNode type.. So it means that swagger doesnt do any conversion to referenced model? — Olekso

No idea. Can you try the latest version of Inflector, 2.0.0-rc0? — Helen

The next problem was found: My model objects (Point) was placed in wrong package. If inflector cant find model it will pass JsonNode to Controller method. Thats why i have recieved argument type mismatch. Java was unable to map JsonNode to Point.

Hope it will help to someone!
