Design an application with multiple request sources: WS(SOAP\REST), MQ, batch

I have to design an application which gets requests from multiple sources like Web service (can be SOAP or REST), online system, Message Queue or some batch job. Application needs to interface with 2 more applications for getting results. I understand that this can be done using microservices. Can someone help me kick start with designing the architecture? Any pointers would help. This application needs to be built in Java.
