6-7 店铺列表展示之controller层的实现、非法登录及重定向

编辑 ShopManagementController

1、根据用户信息返回用户创建的店铺列表

@Controller
@RequestMapping("/shopadmin")
public class ShopManagementController {
	@Autowired 
	private ShopService shopService;
	@Autowired
	private ShopCategoryService shopCategoryService;
	@Autowired
	private AreaService areaService;
	@RequestMapping(value="/getshoplist",method=RequestMethod.GET)
	@ResponseBody
	//根据用户信息返回用户创建的店铺列表
	private Map<String,Object> getShopList(HttpServletRequest request){
		Map<String,Object> modelMap = new HashMap<String,Object>();
		PersonInfo user = new PersonInfo();//模拟用户登录
		user.setUserId(1L);
		user.setName("test");
		request.getSession().setAttribute("user", user);
		user = (PersonInfo) request.getSession().getAttribute("user");
		try {
			Shop shopCondition = new Shop();
			shopCondition.setOwner(user);
			ShopExecution se = shopService.getShopList(shopCondition, 0, 100);
			modelMap.put("shopList", se.getShopList());
			modelMap.put("user", user);//用户信息返回前台
			modelMap.put("success", true);
		} catch (Exception e) {
			modelMap.put("success", false);
			modelMap.put("errMsg", e.getMessage());
		}
		return modelMap;
	}

2、getShopManagementInfo管理session相关的操作

当用户非法直接访问该URL时，查看前端传来的id和session，若没有则重定向，否则可以查看页面

@Controller
@RequestMapping("/shopadmin")
public class ShopManagementController {
	@Autowired 
	private ShopService shopService;
	@Autowired
	private ShopCategoryService shopCategoryService;
	@Autowired
	private AreaService areaService;
	@RequestMapping(value="/getshopmanagementinfo",method=RequestMethod.GET)
	@ResponseBody
	private Map<String,Object> getShopManagementInfo(HttpServletRequest request){
		Map<String,Object> modelMap = new HashMap<String,Object>();
		//先尝试从前端获取
		long shopId = HttpServletRequestUtil.getLong(request, "shopId");
		if(shopId <= 0) {
			//如果前端没有传shopId过来，则从session里获取
			//即当用户不登录直接访问该页面时，将用户重定向到o2oDemo/shop/shoplist中
			Object currentShopObj = request.getSession().getAttribute("currentShop");
			if(currentShopObj == null) {
				//如果还找不到shopId则重定向到o2oDemo/shop/shoplist
				modelMap.put("redirect", true);
				modelMap.put("url", "o2oDemo/shop/shoplist");
			} else {
				//在session中找到了shopId
				//即如果用户之前登录过系统，则可以直接登录访问
				Shop currentShop = (Shop) currentShopObj;
				modelMap.put("redirect", false);
				modelMap.put("shopId", currentShop.getShopId());
			}
		} else {
			//从前端获取到shopId
			Shop currentShop = new Shop();
			currentShop.setShopId(shopId);
			request.getSession().setAttribute("currentShop", currentShop);
			modelMap.put("redirect", false);
		}
		return modelMap;
	}
}
