authentication - Propagating user information to all layers in Dropwizard -

i using basic authentication mechanism in dropwizard application, capturing logged in user details, this:

@post @timed @consumes(mediatype.application_json) @produces("application/pdf") @path("/") @rolesallowed("user,admin") public response function(@auth user user) throws exception {     //some logic around here } 

now auditing purposes, want user information passed @ each layer of application, mean in services, daos, exceptionmappers etc , don't want pass function parameter everywhere looks clumsy , has maintainability overhead. question is, there way can set global configuration per rest call or user session , can fetch anywhere want? have been ruby user , in able this:

thread.current[:user] = user 

which accessible throughout per user session.

one way achieve using threadlocal of java wherein can set user object , available particular executor thread.

add following resource class.

private static threadlocal<user> localuser = new inheritablethreadlocal<>();  public static shortenerserviceuser getuser() {     return localuser.get(); } 

whennever function() method invoked, need set user object threadlocal variable.

localuser.set(user); 

now, whenever need access user object current thread context, need follows

user localuser = yourresource.getuser(); 

you can clear user object context using threadlocal.remove() method.
