spring RequestContextHolder 配置问题！

[a864473066]

public abstract class AbstractService {

	final protected Logger logger = LoggerFactory.getLogger(getClass());
	
	/**
	 * 获得request对象
	 * @return
	 */
	public HttpServletRequest getHttpRequest(){
		HttpServletRequest request=((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
		return request;
	}
}

上面是公司的代码，service的父类。

百度上说使用RequestContextHolder类需要在web.xml文件中配置一个listener
like this:

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

但公司应用中的web.xml中并没有：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

小弟想问下，除了在web.xml中配置listener外还有什么方法可以配置RequestContextHolder呢？
多谢！
