How to get Client IP address in Spring bean

I have define a Spring bean. 

<beans>
  <bean id="remoteService" class="edu.wustl.catissuecore.CaTissueApplictionServicImpl" />
</beans>

Is there any way to get the IP address of client in this class? Similarly as available in the servlet request.getRemoteAddr();

The best way to get client ip is to loop through the headers 

   private static final String[] IP_HEADER_CANDIDATES = {
        "X-Forwarded-For",
        "Proxy-Client-IP",
        "WL-Proxy-Client-IP",
        "HTTP_X_FORWARDED_FOR",
        "HTTP_X_FORWARDED",
        "HTTP_X_CLUSTER_CLIENT_IP",
        "HTTP_CLIENT_IP",
        "HTTP_FORWARDED_FOR",
        "HTTP_FORWARDED",
        "HTTP_VIA",
        "REMOTE_ADDR" };

public static String getClientIpAddress(HttpServletRequest request) {
    for (String header : IP_HEADER_CANDIDATES) {
        String ip = request.getHeader(header);
        if (ip != null && ip.length() != 0 && !"unknown".equalsIgnoreCase(ip)) {
            return ip;
        }
    }
    return request.getRemoteAddr();
}

Construct this:

@Autowired(required = true)
private HttpServletRequest  request;

and use like this:

request.getRemoteAddr()

The simplest (and ugliest) approach is to use RequestContextHolder:

  String remoteAddress = ((ServletRequestAttributes)RequestContextHolder.currentRequestAttributes())
       .getRequest().getRemoteAddr();

Without knowing more about your bean and how it's wired up, that's the best I can suggest. If your bean is a controller (either subclassing AbstractController or being annotated with @Controller) then it should be able to get direct access to the request object.
