 3     private Map<String , Object> getShopList(HttpServletRequest request){
 4         Map<String, Object> modelMap = new HashMap<String,Object>();
 5         PersonInfo user = new PersonInfo();
 6         //因为如果没有用户登录 所以先设置个默认值 模拟用户登录
 7         user.setUserId(1L);
 8         user.setName("test");
 9         request.getSession().setAttribute("user", user);
10         
11         user = (PersonInfo) request.getSession().getAttribute("user");
12         try {
13             Shop shopCondition = new Shop();
14             shopCondition.setOwner(user);//将Session中的user获取到
15             ShopExecution se = shopService.getShopList(shopCondition, 0, 100);//一个人最多创建一百条
16             modelMap.put("shopList", se.getShopList());
17             modelMap.put("user", user);
18             modelMap.put("success", true);

20             modelMap.put("success", false);
21             modelMap.put("errMsg", e.getMessage());

10         long shopId = (long) request.getSession().getAttribute("shopId");
11         //如果shopId不存在
12         if(shopId <= 0){

14             Object currentShopObj = request.getSession().getAttribute("currentShop");
15             //如果当前既没有shopId传入，也没有店铺登录的话，就重定向到店铺列表页面
