Configuring JsonPOJOBuilder "withPrefix" on external configuration file

[ghost]

It would be really nice if the default withPrefix property in JsonPOJOBuilder could be exposed in a property file. (Same goes for some of the other properties, but this is the one I want to focus on)

That way, when I am writing my builder according to company standards, I don't have to worry about adding the annotation manually. Also consider that when using lombok, the @builder annotation, the builder methods are just variablename and not withVariablename.

I think the more configurable a project can be, the better.

Jackson does not directly support any form of external configuration (either from properties or via system properties), and this is by design.

I would be open to additional module(s) for support such configurability, but I don't think it belongs in core jackson-databind. It probably would make sense to do that as part of 3.0 version as well, since that will use builder-style construction where this might plug in nicely (maybe).

So you may want to file this at:

Another thing to consider is that on short term you can sub-class JacksonAnnotationIntrospector and use different mechanism for exposing configuration same as if annotations were used.
Source could be external config file or such.
And finally, mix-in annotations can sometimes work as well.

I have no plans to implement configuration system that uses external configuration files: this sounds like something an extension project could tackle, or maybe module.
Will move to "future ideas" repo.
