我正在使用 Spring MVC、Tiles 2.2 和 jquery 来进行 ajax 调用，但是我的 js 文件中的 ajax 没有击中我的控制器。我如何正确配置它，因为这是我第一次尝试使用注释使用 spring mvc 进行 ajax 调用..

我的 javascript 文件使 jquery 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;
    }

}

为什么你使用@ResponseBodywithModelAndView

@ResponseBody如果您想根据内容类型将响应对象作为 JSON 或 XML 获取，则使用此选项。

ModelAndView如果您想使用视图框架 jsp 磁贴之一或其他任何东西来显示视图，则使用此选项。

对于 ajax 调用，您必须使用@ResponseBody并制作另一种方法来呈现您的瓷砖页面
