Mark Struberg commented on JOHNZON-169:
---------------------------------------
hiho! I've read through the spec and JavaDoc and I fear we have some gaps in
both. I've now created a spec ticket for it
[https://github.com/eclipse-ee4j/jsonb-api/issues/89.]
So far Johnzon supports annotating the field (or setter):
{code:java}
public class SomeStudentsList {
@JsonbTypeDeserializer(StudentDeserializer.class)
private List<Student> students = new ArrayList<>();
}
{code}
Note that this supports the case where you have a json for each Student. If you
just have a String then you would need to use a `JsonbAdapter`.
> @JsonbTypeDeserializer(xxxJsonbDeserializer.class) is not working properly

> Key: JOHNZON-169
> URL: https://issues.apache.org/jira/browse/JOHNZON-169
> Project: Johnzon
> Issue Type: Bug
> Components: JSON-B
> Affects Versions: 1.1.7
> Environment: JDK8, Windows 10
>
> Reporter: Miroslav Nachev
> Assignee: Mark Struberg
> Priority: Blocker
>
> I have made my own JonsArray converter in JavaClass, which works properly
> when called alone. For this purpose, I have used an annotation:
> @JsonbTypeDeserializer(Student.StudentDeserializer.class)
> public class Student \{...}
> public static class StudentDeserializer implements JsonbDeserializer<Student>
> \{...}
> The problem comes, when this object Student is part of an array (List), that
> is located in another object:
> public class SomeStudentsList {
> private List<Student> students = new ArrayList<>();
> }
> json=\{"students":[["Value-1","Value-2","Value-N"],
> ["Value-1","Value-2","Value-N"], ["Value-1","Value-2","Value-N"]]}
> The result exception is:
> Exception in thread "main" java.lang.UnsupportedOperationException: type
> class eu.nscenter.scilearn.manage.Student not supported
