This is the provider definition:

<code>
  @GetMapping(path = "/diffNames")
  @ApiOperation(value = "differentName", nickname = "differentName")
  public int diffNames(@RequestParam("x") int a, @RequestParam("y") int b)
</code>

and the swagger is:

<code>
  paths:
    /diffNames:
      get:
        summary: "differentName"
        operationId: "differentName"
        parameters:
        - name: "x"
          in: "query"
          required: true
          type: "integer"
          format: "int32"
        - name: "y"
          in: "query"
          required: true
          type: "integer"
          format: "int32"
        responses:
          "200":
            description: "response of 200"
            schema:
              type: "integer"
              format: "int32"
</code>

In consumer, you can define any prototype that matches generated swagger of provider.
