8 years ago Hi @massfords ,
We already Identified this issue and currently in progress of developing the solution. We thought of using pluggable serializer to extract object to relevant audit record based on annotations in the object fields (ex: MyDTO). I have developed below couple of serializes similar to old toString implementation. Please refer below implementations.
Using this method, users are able to plug their own serializer implementation based on the requirement (Ex: JSONable, XML). then you don't need to implement a custom a annotation transformer
What do you think.

Very nice library!
The conversion of the method args to a List is based on the arg's toString() implementation. It would be nice to support a pluggable conversion from object to a String or even support producing multiple Field's from a single argument.
Consider the following case:
In this case, I'd like to record a couple of different fields from the MyDTO arg as opposed to relying solely on its toString() implementation.
I'm thinking I can add the behavior I want by writing my own version of AnnotationTransformer and then using it in an AuditOutputStream but it would be nice if this had a declarative / annotation driven solution. For spring users in particular, it would be great to have the option of an annotation that produced a List using different names and SpEL (spring expression language). For example, I could annotate the above method with an array of annotations each one having a name and SpEL that would extract the field I want to include in the AuditEvent.
