java - Creating Spring-backed actors as routees -

problem: have thread pool allocated number of actors making blocking calls (eg. web service, database, etc).

i have following configuration:

threadpool-dispatcher {   type = dispatcher   executor = "thread-pool-executor"   thread-pool-executor {     core-pool-size-min = 4     core-pool-size-max = 8   } } 

and following setup method router actor:

private final int numberofchildren = 4;  @override public void prestart() throws exception {     log.info("starting up.. creating {} children", numberofchildren);     list<routee> routees = new arraylist<>();     (int = 0; < numberofchildren; i++) {         actorref actor = getcontext().actorof(springactorextension.props(routeeclass)                                 .withdispatcher(threadpool_dispatcher));         getcontext().watch(actor);         routees.add(new actorrefroutee(actor));     }     router = new router(new smallestmailboxroutinglogic(), routees);     super.prestart(); } 

springactorextension similar code presented here, uses class objects instead of names.

the routees created spring in end, example:

@bean @scope(value = "prototype") public httpclientactor httpclient() {     return new httpclientactor(); } 

all works fine, problem number of threads thread pool executor configured use must declared @ 2 places:

1. in threadpool-dispatcher configuration
2. in code of router (numberofchildren)

reading through akka docs there seems way create routees automatically based on configuration alone, eg.

akka.actor.deployment {   /parent/router1 {     router = round-robin-pool     nr-of-instances = 5   } } 

however, not how (by whom) should routee actors created.

is there way either

1. explain akka have routees created spring
2. or access thread-pool-executor configuration (eg. number of threads) in code above , remove need specifying number of threads 2 times.
