ajax调用不打我弹簧mvc控制器使用它与瓷砖2.2

我正在使用Spring MVC，瓷砖2.2和jQuery使ajax调用，但我的AJAX在我的js文件没有击中我的控制器。我如何正确地配置它，因为这是我第一次试图与使用Spring MVC的注解Ajax调用..ajax调用不打我弹簧mvc控制器使用它与瓷砖2.2

我的JavaScript文件，使jQuery的AJAX调用

function showSubCategory(foodCategoryId){ 
    var params = {foodCategoryId : foodCategoryId}; 
    $.ajax({ 
     type : GET, 
     url : "subMenu.json", 
     dataType : "json", 
     contentType : "application/json", 
     data : params, 
     success : 
      alert("success" + data), 
     error : showError() 
    }); 
} 

function showError(){ 
    alert("An error occured."); 
}

这是我的控制器

@Controller 
@SessionAttributes 
public class MenuController { 

    private static Logger logger = Logger.getLogger("MenuController.class"); 

    @Autowired 
    private MenuService menuService; 

    @RequestMapping(value="/subMenu") 
    public @ResponseBody ModelAndView showSubCategories(HttpServletRequest req, HttpServletResponse res){ 
     String foodCategoryId = req.getParameter("foodCategoryId"); 
     logger.info("hitting showSubcatregories controller " + foodCategoryId); 
     ModelAndView mav = new ModelAndView("ajax.menu"); 

     mav.addObject("subCategories", menuService.getMenuByFoodCategory(1L, Long.parseLong(foodCategoryId))); 
     return mav; 
    } 

}

，如果你想根据内容类型来获得响应对象为JSON或XML为什么你正在使用@ResponseBody与使用ModelAndView

@ResponseBody 。

ModelAndView如果您想使用视图框架jsp图块或任何其他东西中的一个来显示视图，请使用它。

对于ajax调用你必须使用@ResponseBody并使另一种方法来渲染你的瓷砖页面
