A. Lepe updated GROOVY-10208:
-----------------------------
Description:
Json classes in `groovy.json` do not support `LocalDate`, `LocalTime`,
`LocalDateTime`, etc classes.
Classes like `Date`, `Calendar` and `SimpleDateFormat` are used, which (as you
know) are no longer recommended. It would be nice to replace those classes with
the recommended ones.
Affected classes:
* DefaultJsonGenerator
* JsonGenerator
* JsonOutput
Example:
{code:java}
// Setting date and time in JSON:
def map = [
date : LocalDateTime.now()
]
def json = new JsonBuilder(map).toPrettyString()
println json
// prints:
{
"date": {
"dayOfYear": 242,
"month": "AUGUST",
"second": 56,
"hour": 15,
"nano": 337326000,
"year": 2021,
"dayOfMonth": 30,
"minute": 51,
"monthValue": 8,
"dayOfWeek": "MONDAY",
"chronology": {
"calendarType": "iso8601",
"id": "ISO"
}
}
}
// Parsing that object with JsonSlurper:
def importMap = new JsonSlurper().parseText(json)
println importMap.date
// prints:
[dayOfYear:242, month:AUGUST, second:56, hour:15, nano:337326000, year:2021,
dayOfMonth:30, minute:51, monthValue:8, dayOfWeek:MONDAY,
chronology:[calendarType:iso8601, id:ISO]]
{code}

Alternatively some way to add custom converters into JSON (similar to
`GsonBuilder.registerTypeAdapter` (from Google gson library).
