Subject [jira] [Commented] (JOHNZON-203) How do I map a Java Bean to javax.json.JsonValue?
Date Wed, 20 Feb 2019 10:02:00 GMT


Mark Struberg commented on JOHNZON-203:

I suggest we still solve this at least in our Mapper.

There is one very important use case for it: You transform an Object but then you want to
modify the {{JsonObject}}, eg if you want to adopt it to an old version.

>          Issue Type: New Feature
>    Affects Versions: 1.1.11
>            Reporter: Alexander Falb
>            Priority: Major
> From what I understand {{org.apache.johnzon.mapper.Mapper}} is ment to map Java Beans
to JSON strings.
> Is there a way to map from a Java Bean to a {{javax.json.JsonValue}} and from JsonValue
to a JSON string?
> I would need the intermediate JsonValue based structure for further processing before
writing the final JSON string. The only way I'm curently aware of is writing the JSON string
and reading it again with {{javax.json.Json.createReader(new StringReader(jsonString)).readObject()}},
which is ok as a workaround, but not optimal as final solution.
