同学好，其实同学可以站在业务的角度去理解，就清晰了。currentShop是当你在店家能够管理的店铺列表里选择进入其中一个店铺的时候，会在session里设置上。

private Map<String, Object> getShopManagementInfo(HttpServletRequest request) {
		Map<String, Object> modelMap = new HashMap<String, Object>();
		long shopId = HttpServletRequestUtil.getLong(request, "shopId");
		if (shopId <= 0) {
			Object currentShopObj = request.getSession().getAttribute("currentShop");
			if (currentShopObj == null) {
				modelMap.put("redirect", true);
				modelMap.put("url", "/myo2o/shopadmin/shoplist");
			} else {
				Shop currentShop = (Shop) currentShopObj;
				modelMap.put("redirect", false);
				modelMap.put("shopId", currentShop.getShopId());
			}
		} else {
			Shop currentShop = new Shop();
			currentShop.setShopId(shopId);
			request.getSession().setAttribute("currentShop", currentShop);
			modelMap.put("redirect", false);
		}
		return modelMap;
	}

之后只要session还有效就能从session中获取到店铺
