if you are looking to get ip address from servlet, inject HttpServletRequest and call in request.getRemoteAddr() method.

and if you're using reverse proxy request, check out this answer's comment https://stackoverflow.com/a/29910902/8733302

@RestController
public class HelloController {

    @Autowired
    private HttpServletRequest request;

    @PostMapping("/coolendpointTWO")
    public String withRequestBody(@RequestBody MyPojo myPojo) {

        System.out.println("received object" + myPojo);
        //handle myPojo with my business logic

        String ip = request.getRemoteAddr();
        return "good: " + ip;
    }

}
