David Blevins updated JOHNZON-417:
----------------------------------
Description:
Attempting to serialize or write class Email as follows
{code:java}
final Jsonb jsonb = JsonbBuilder.create(new JsonbConfig().withAdapters(new
Adapter.Config()));
final String json = "\{\"user\":\"test\",\"domain\":\"domain.com\"}";
final Email email = jsonb.fromJson(json, Email.class);{code}
and adapter code
{code:java}
public static class Config implements JsonbAdapter<Email, Map<String, Object>> {
@Override
public Map<String, Object> adaptToJson(final Email obj) {
final LinkedHashMap<String, Object> map = new LinkedHashMap<>();
map.put("user", obj.user);
map.put("domain", obj.domain);
return map;
}
@Override
public Email adaptFromJson(final Map<String, Object> map) {
return new Email(map.get("user").toString(),
map.get("domain").toString());
}{code}
fails and the JsonbAdapter specified in the JsonbConfig will not be invoked
{code:java}
public static class Email {
private final String user;
private final String domain;
public Email(final String user, final String domain) {
//..
}
//... {code}
will fail with exception
{code:java}
jakarta.json.bind.JsonbException: Email has no suitable constructor or factory.
Cannot deserialize json object value: {"user":"test","domain":"domain.com"}
Use Johnzon @ConstructorProperties or @JsonbCreator if constructor arguments
are needed
class org.apache.johnzon.jsonb.symmetry.adapter.map.MapAdapterOnClassTest$Email
not instantiable{code}
if the {{Email}} class is annotated with {{@JsonbTypeAdapter}} the error will
be as indicated in JOHNZON-416
This this will work for a write if the adapter operates on a String or List and
the {{Adapter.Config}} specified in the configuration will be used.
