How to get Client IP address in Spring bean

Question

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();

Answer 1

It depends on what kind of bean you have. If you have an AbstactController you have access to the HttpServletRequest object in the handleRequest method.

Answer 2

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.
