java json date jsonschema

Solution 1

JSON Schema already have defined format for date, time, datetime, email, hostname, IP address. You can prefer this easier and recommended method rather than writing your own regex.

"date": {
  "type": "string",
  "format": "date"
}

Date and time format names are derived from RFC 3339, section 5.6 [RFC3339].

Reference: http://json-schema.org/latest/json-schema-validation.html#rfc.section.7.3

Solution 2

add regex to json schema in schema use the following.

{
   "type": "string",
   "pattern": "^\d{4}\-(0?[1-9]|1[012])\-(0?[1-9]|[12][0-9]|3[01])$"
}

Could someone tell me JSON Schema Validation for accepting date of YYYY-MM-DD format alone?

My sample JSON:
```
{"data1" : "foo", "date" :"2016-11-24"}
```

\d is not part of the supported subset of regex features.

As per the JSON specification, it seems that these formats are not mandatory. Is this correct? json-schema.org/understanding-json-schema/reference/…

@リカルド I think this note is unambiguous: "JSON Schema implementations are not required to implement this part of the specification, and many of them do not."

Isn't it the same solution as this answer?

Please note that the documentation also states that the "format" is more of an annotation and doesn't trigger any validation without 3rd party libraries.

The documentation states that format does not affect validation.

It has based on the json schema validator you use. I mostly use ajv which considers the format field and will validate. You may need to check with the validator you using. @TroyWeber
