Subject [jira] [Commented] (JOHNZON-80) Serialization of Maps should take AttributeOrder into account
Date Tue, 31 May 2016 07:46:12 GMT


Robert Panzer commented on JOHNZON-80:

This works in the concrete case, thanks!

But the data structure to serialize might be not modifiable.
Or if it's an JPA Entity and the Map to serialize is a persistent attribute this might have
a serious impact if not handled properly (Detaching it before).

Just some ideas what might happen.

>          Components: Mapper
>    Affects Versions: 0.9.2-incubating
>            Reporter: Robert Panzer
> MapperBuilder allows to pass a java.util.Comparator to define the AttributeOrder, e.g.
write Object properties in their lexicographic order.
> It seems that this order is ignored when java.util.Maps are serialized.
> It would be nice if the AttributeOrder would be used in this case as well.
> Tested on Johnzon 0.9.2-incubating, but looking at the current master it seems that this
behavior is still in place even though the code was a bit refactored.
