Force root wrapping per class about jackson-annotations

Is there a plan to include this one in near future? We are quite depending on it, so we need to plan at least :)

[cowtowncoder]

Yes, that sounds reasonable the way you suggest.

[cowtowncoder]

Added as suggested; need to add support in jackson-databind next.

[cowtowncoder]

Hmmh. Actually, may need to re-think this one... unfortunately there is bit of a speed bump that I ignored earlier. Problem being that to find the flag, a lookup is needed. I need to think about this a bit more.

[cowtowncoder]

Ok, I will have to revert this, since I don't think I can figure it out before 2.4.0 release. Will leave this open so that hopefully it can be included in 2.5.

[cowtowncoder]

Note: was not included in 2.5.

[odrotbohm]

You might wanna clean up the JavaDoc on @JsonRootName accordingly as it still indicate the functionality might be (or better: have been, which it hasn't) introduced in 2.5.

Other than that, +1 for adding this :).

[cowtowncoder]

@jbm4sa No one working actively on this that I am aware of. Contributions welcome. But I will move this to jackson-databind as it is implement there, even if a tiny part may be relevant here; issues reported here are easier to ignore as well.

[cowtowncoder]

Moved to FasterXML/jackson-databind#1022

Is there any way to remove default root wrapping? I want to send json without root element and I am not giving @JsonRootName still its wrapping with class name? Please suggest something. @chrylis @cowtowncoder

[cowtowncoder]

@mv07517 Couple of ways. ObjectWriter has withoutRootName() method that can be used to do this for specific calls. Or, you may sub-class JacksonAnnotationIntrospector to sort of hide the annotation.

As to why root wrapping seems to be enabled in your case, I do not know. For questions, please use the mailing list in future; or, if you do have what you think is a bug, file a new issue with reproduction. Tagging questions to existing issues tends to make discussions more convoluted and harder to read.

Any progress on this? I am looking at JacksonAnnotationIntrospector but see no way to do this. findRootName() doesn't affect this behavior.

[cxl-todd]

Seems like this is still commented out. Any thoughts on reintroducing this functionality? Would be great to do on a per-class basis rather than affecting the entire object mapper.

[cowtowncoder]

@cxl-todd Unfortunately support was never implemented, even though annotation declaration was accidentally released.
If someone has time to look into this, I could help. But last I checked it seemed difficult to achieve. Esp. compared to relative ease with which one can just wrap root object in a simple Map to achieve the same effect.

[malloc32]

I need this functionally to, I need that object mapper only wrap root when class has the annotation. Any advance?
Thank you.

[cowtowncoder]

@malloc32 for help with usage etc, mailing lists would be the place to ask, not issue. I can't think of anything simple that would do this automatically just based on annotation.
