Utility Method for Spring REST

 public static HttpServletRequest getCurrentRequest() {
     RequestAttributes requestAttributes = RequestContextHolder.getRequestAttributes();
     Assert.state(requestAttributes != null, "Could not find current request via RequestContextHolder");
     Assert.isInstanceOf(ServletRequestAttributes.class, requestAttributes);
     HttpServletRequest servletRequest = ((ServletRequestAttributes) requestAttributes).getRequest();
     Assert.state(servletRequest != null, "Could not find current HttpServletRequest");
     return servletRequest;
 }

Sometimes it’s easier to get the underlying Servlet request to get some headers or variables.

 final String userIpAddress = getCurrentRequest().getRemoteAddr();
 final String userAgent = getCurrentRequest().getHeader("user-agent");

This is used in the simple REST service using HTTP Post verb @ the awesome CloudFoundry:
