Kendo UI甘特图未加载数据

Question

我正在尝试在jsp文件中使用kendo-ui-gantt图表。我在这个项目中使用springmvc和maven。我遵循了春季演示中给出的教程，但仍然没有得到结果。jsp页面中没有显示任何内容。

控制器

@Controller
public class IndexController {
    @Autowired 
    private GanttTaskDao taskDao;
    @Autowired 
    private GanttDependencyDao dependencyDao;
    @RequestMapping(value = "/index", method = RequestMethod.GET)
    public String index(Locale locale, Model model) {        
        return "index";
    }
    @RequestMapping(value = "/tasks/read", method = RequestMethod.POST)
    public @ResponseBody List<GanttTask> read_tasks() {
        return taskDao.getList();
    }
    @RequestMapping(value = "/dependencies/read", method = RequestMethod.POST)
    public @ResponseBody List<GanttDependency> read_dependencies() {
        return dependencyDao.getList();
    }
}

我也使用调试模式来运行该项目，但请求只进行到/index方法，并且没有请求发送到/gant/tasks/read或/gantt/dependency/read方法。

我尝试使用不同的url，以防出现错误。但它仍然不起作用。

我不知道我哪里错了。任何人都知道答案。还有什么我可能遗漏的吗？

好吧，我犯了一个愚蠢的错误，忘记了将js和css文件包含到我的jsp中。我现在已经把它包括在内了。当我使用调试模式时，它会检索任务和依赖项，但不会在我的jsp中显示它。我只能看到空的图表窗口。请有人帮忙。
