public class Json extends Object
Generic JSON encoder using javax.json API.
This supports the standard types Boolean, Number, Character, CharSequence,
Date, LocalDate and Instant.
If the given object type does not match any of them, then it will attempt to inspect the object as a JavaBean
using the Introspector, whereby the public properties (public getters) will be encoded as a JS object.
It also supports arrays, Collections and Maps of them, even nested ones.
The dates are formatted as ISO8601 instant via DateTimeFormatter.ISO_INSTANT, so you can if necessary
just pass the value straight to new Date(value) in JavaScript.
Below encoding options are available:
Json.Option.SKIP_NULL_VALUES: skip null values in arrays, collections, maps and beans.
This may reduce an unnecessarily bloated JSON object.
Json.Option.USE_RFC1123_DATE: format dates as RFC1123 via DateTimeFormatter.RFC_1123_DATE_TIME.
This may improve compatibility with older web browsers.| Modifier and Type | Class and Description |
