Answer 1

@PathVariable - must be placed in the endpoint uri and access the query parameter value from the request
@RequestParam - must be passed as method parameter (optional based on the required property)
 http://localhost:8080/employee/call/7865467

 @RequestMapping(value=“/call/{callId}", method = RequestMethod.GET)
 public List getAgentCallById(
            @PathVariable(“callId") int callId,
            @RequestParam(value = “status", required = false) String callStatus) {

    }

http://localhost:8080/app/call/7865467?status=Cancelled

@RequestMapping(value=“/call/{callId}", method = RequestMethod.GET)
public List getAgentCallById(
            @PathVariable(“callId") int callId,
            @RequestParam(value = “status", required = true) String callStatus) {

}
