[Spring] Generated controllers ignore basePath

I have the following line in the openapi file:

```
basePath: "/v1"
```

I would expect generated controllers (interfaces) would use this basePath as prefix for all the paths, but they don't contain this "v1" and just use resource path:

```
@RequestMapping(value = "/abc", method = RequestMethod.GET)
```

I'm using latest stable release 3.3.4.
