Parameters injection

[aesteve]

For now, we only have the RoutingContext as parameter but, an interesting feature would be to outbox and convert parameters for the end-users and inject it to the method.

Like : public void search(RoutingContext context, SearchCriteria criteria) where criteria is instanciated from request parameters.

First implementation possible, let user define their class by implementing an interface : fromRequestParams(MultiMap ... blah)` then provide some utility methods upon that.

Standard parameters are injected with QueryParam, PathParam

Next step : marshall requests body as a "backing object" with a user provided marshaller (and defaults implementations : Boon for JSON, manually for XML ?)

TODO :

• handle a lot more object types out of the box : Decimals, Dates, Enums
• Something like : @RequestBody("some.node") MyObject stuff => populate by reflection (or a lib like boon for Json)
• handle FormParam or even better FormBackingObject (same kind of stuff than above)
• handle fileuploads (maybe not... will need for the whole file to be transferred, ...) Especially if users just want to store some data to the disk. Or maybe just provide a @StoreTo kind of annotations so that we just write some efficient FileUpload facility

[aesteve]

Done :

• Param for both query and forms params (i.e. context.request().params())
• Params for backing a set of params onto an object by reflection
• RequestBody to unmarshall request body in case it's an API
• automatically attach bodyhandler to every POST and PUT requests
