spring aop中获得request

@Component
@Aspect
public class SysLogAspectJ {

	@Autowired
	private HttpServletRequest request;

web.xml

<listener>
		<listener-class>
			org.springframework.web.context.request.RequestContextListener
		</listener-class>
	</listener>

有人说用threadLocal 实现一下，其实看这个监听能发现也是用的这个方式。
