彈簧mvc url參數

Question

我無法顯示可能的餐廳。 I.ve了我的控制器類：

@Controller 
public class RestaurantController extends MultiActionController{ 

    private RestaurantDAO restaurantDAO; 

    public void setRestaurantDAO(RestaurantDAO restaurantDAO) { 
     this.restaurantDAO = restaurantDAO; 
    } 


    @RequestMapping("/restaurant/{restaurantId}") 
    public ModelAndView restaurantid(@PathVariable("contactId") int id, 
     HttpServletRequest request, 
     HttpServletResponse response) throws Exception { 

     Restaurant restaurant = restaurantDAO.findRestaurantById(id); 
     ModelMap modelMap = new ModelMap(); 
     modelMap.addAttribute("restaurant", restaurant); 
     return new ModelAndView("restaurant", modelMap); 
    } 
} 

IM我的jsp只是：

<c:out value="${restaurant.name }" 

在我爲spring-servlet.xml

：

<bean name="/restaurant/**" class="web.RestaurantController" > 
<property name="restaurantDAO" ref="myRestaurantDAO"/> 
</bean> 

Answer 1

因爲你混了restaurantId和contactId

@RequestMapping("/restaurant/{restaurantId}") 
public ModelAndView restaurantid(@PathVariable("contactId") ... 

我想當你改變@PathVariable("contactId")到@PathVariable("restaurantId")它會工作。

並添加@RequestMapping("/restaurant/**")到控制器：

@RequestMapping("/restaurant/**") 
@Controller 
public class RestaurantController extends MultiActionController{ 

BTW：什麼是MultiActionController的？
