import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;
import javax.servlet.http.HttpSession;
import javax.servlet.http.HttpServletRequest;

ServletRequestAttributes sra = (ServletRequestAttributes)RequestContextHolder.currentRequestAttributes();


// HttpServletReqeust 객체
HttpServletReqeust httpServletReqeust = sra.getRequest();

// HttpSession 객체
HttpSession httpSession = sra.getRequest().getSession();
