我想在一個jsp文件中使用kendo ui甘特圖。我爲這個項目使用了spring mvc和maven。我按照春季演示中給出的教程，但仍然沒有得到結果。沒有什麼會顯示在jsp頁面中。Kendo UI甘特圖不加載數據

@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();
}
}
我還用調試模式下運行該項目，但要求會只直到/指數法，沒有要求越來越發送到/甘特圖/任務/讀取或/甘特/依賴/讀取方法。
我試過使用不同的網址，以防萬一可能會出現一些錯誤。但它仍然沒有工作。
我不知道我出錯的地方。任何人都知道答案。還有什麼我可能會失蹤？
