SpringFox Swagger and LocalTime

Question

Anybody knows how to format LocalTime in Springfox? Converting to ISO format works for LocalDate with this setting to ObjectMapper

.featuresToDisable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS)

But for LocalTime I'm still getting this in example and model of swagger-ui

"time": {
  "hour": "string",
  "minute": "string",
  "nano": 0,
  "second": "string"
}

I have read something that swagger spec do not use time format. Is this somewhat connected?

Springfox does not know anything about the serialization features used, nor is there a good way to ask Jackson to figure it out.

However, you can help springfox along by providing model substitution rules. These are basically a way to change the schema of the model that is rendered in the specificiation. In your case a date/time would be represented as a time stamp which is really a long.

So in your Docket you would add a directModelSubstitute to substitute the LocalTime with Long :

docket.directModelSubstitute(LocalTime.class, Long.class)
