I ran into a problem where the Swagger2 JSON document generated from a SpringBoot application with the following API method:

  @RequestMapping(...)
  @ResponseStatus(...)
  public void setThreshold(..., @RequestBody int threshold) { ... }

would include the following for the @RequestBody parameter

{
  "in": "body",
  "name": "threshold",
  "description": "threshold",
  "required": true,
  "schema": {
    "type": "int"
  }
}

This JSON has "int" for the "type" property, when it should be "integer", with "format": "int32".

This pull request updates ParameterMapper to ensure that it uses io.swagger.models.properties.Property for the "schema" "type" and "format" information, similar to what is done for collections and maps in that class.
