Add multiple optional format validators like java.time.format.DataTimeFormatterBuilder

[jacob2221]

Hi,

I have a field in JSON which may either just have a DATE in yyyy-MM-dd format or DATETIME in yyyy-MM-dd HH:mm:ss format. Similar to java.time.format.DateTimeFormatterBuilder where we can append optional formats to a base format, is there any way to do the same in everit without defining our own custom date format validator or any other code changes?

type: "string",
format: "date",
format:"time"

Regards

Hello, adding duplicate keys to the schema json won't work, since keys in json should be unique (parsers will either throw an error, or pick one of the provided values).

On the other hand, you can do this with the "anyOf" json schema keyword as follows:

{
  "anyOf": [
    {
      "type": "string", "format": "date"
    },
    {
      "type": "string", "format": "datetime"
    }
  ]
}

By the way, this library is in maintenance mode, and it is very unlikely to see newer releases (and also won't support the latest version of json schema). I suggest migrating to https://github.com/erosb/json-sKema
