In your Spring Rest Controller you can add HttpServletRequest to get client info.

Example

@GetMapping("/dummyurl")
public Boolean syncWithServNow(HttpServletRequest httpReq, @RequestParam("username") String username) {
    System.out.println(httpReq.getRemoteAddr());  // Line 1
}

In most cases it will work. In case like url is accessed by web server over a proxy server or has a load balancer this will do.

httpReq.getHeader("X-FORWARDED-FOR");
