Event-driven Service Generating System

SOA(Service Oriented Architecture)plays an important role in Internet,it has the characteristics of code reuse,loose coupling,platform independence and language-neutral.Although SOA has so many advantages,it has some limitations in real-time distributed?decoupling and initiative,and cannot satisfy the needs of service architecture in the future.Under the background of the Internet of Things,the service architecture has real-time distributed,dynamic interactive features and can interact with us based on the events which we are interested in.In order to realize this architecture,we should make the integration of the SOA and EDA,generating EDSOA(event-driven service)has become inevitable trend,EDSOA are loosely coupled,highly integrated,dynamic collaborative,real-time distributed,it can adapt to the demand under the background of the Internet of Things.To achieve this extension,this paper raises the design and implementation about event-driven service generating system:first of all,our atomic services are based on the event-driven characteristics,so we generate services based on the Actor model;Secondly,make Atomic services integrate into composite services,in addition to the event,there are logical relationship between events,our events is from publish-subscribe system,so the atomic service should connect to the publish-subscribe system;Moreover,our original SOA platform doesn't have the characteristics of the event,so we also need to develop SOA plug-in,add the events,event logic,and the connecting-line between event,event logic and service,at last,we need to implement some other functions in service generating system.Finally,we need to do the corresponding test,the experimental results show that our design and implementation of the system can meet the demand of our expectations.
