java - What is the best approach to use multiple services inside a resource controller? -

i have controller call 3 services :

public class productcontroller(){ @autowired private accountservice accountservice; @autowired private processservice processservice; @autowired private releaseservice releaseservice;  @requestmapping("/process")     public product process(@requestparam(value="name", defaultvalue="docs")     productprocessed process) {      accountservice.notify();     releaseservice.sendrelease(process);       return processservice.process(process); } 

}

what best approach encapsulate service calls??

what looking possibly design patterns. approach create coarse-grained facade on fine-grained services (account, process , release). (see coarse-grained vs fine-grained)

the facade have these 3 services injected in them , encapsulate behavior making controller perform currently. way minimize business logic invoking coarse grained service in controller further encapsulating guts of system.
