Swagger: How to stub REST service with Java code/annotations

This pice of code might be helpful for your question. 

 @GET
 @Path("/findByStatus")
 @ApiOperation(value = "Finds Pets by status",
    notes = "Multiple status values can be provided with comma seperated strings",
    response = Pet.class,
    responseContainer = "List")
 public Response findPetsByStatus(...) { ... }

In the response parameter you can put a class, in your case: MyObject.class.
You can also add metadata to your model, with the @ApiModelProperty annotation, in class and parameters level. 

@ApiModel(value="DifferentModel", description="Sample model for the documentation")
class OriginalModel {...}

 @ApiModelProperty(value = "pet status in the store", allowableValues = "available,pending,sold")
  public String getStatus() {
    return status;
  }

Have a nice day!
