A. Lepe commented on GROOVY-10208:
----------------------------------
I found the way to add support to those classes, so I will close this request.
Example:
{code:java}
JsonBuilder jb = new JsonBuilder(object , new JsonGenerator.Options()
.addConverter(LocalDateTime, { it.format("yyyy-MM-DD HH:mm:ss")
})
.addConverter(LocalDate, { it.format("yyyy-MM-DD")})
.addConverter(LocalTime, { it.format("HH:mm:ss") })
.build()
{code}
> Add LocalDate/LocalTime/LocalDateTime support in JsonBuilder
> ------------------------------------------------------------

> Key: GROOVY-10208
> URL: https://issues.apache.org/jira/browse/GROOVY-10208
> Project: Groovy
> Issue Type: Improvement
> Affects Versions: 3.0.8
> Reporter: A. Lepe
> Priority: Trivial
> Labels: json, jsonBuilder
>
> 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}
