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：

package com.base.common.sessionutils;

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;
	}

}

这样其他服务层使用的时候，ContextHolderUtils.getRequest();  即可
