疑问 如何再服务层直接拿到HttpServletRequest？

大家都知道 能在Controller/action层获取 HttpServletRequest ， 但是这里给大家备份的 是 从代码内部 service层获取HttpServletRequest 工具类。 具体如下：

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession; 

import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes; 

public class ContextHolderUtils { 
	public static HttpServletRequest getRequest() {	
		HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();			return request;
	}
	public static HttpSession getSession() {
		HttpSession session = getRequest().getSession();
		return session;
	}
}
