我想在一个jsp文件中使用kendo ui甘特图。我为这个项目使用了spring mvc和maven。我按照春季演示中给出的教程，但仍然没有得到结果。没有什么会显示在jsp页面中。Kendo UI甘特图不加载数据

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();
}
}
我还用调试模式下运行该项目，但要求会只直到/指数法，没有要求越来越发送到/甘特图/任务/读取或/甘特/依赖/读取方法。
我试过使用不同的网址，以防万一可能会出现一些错误。但它仍然没有工作。
我不知道我出错的地方。任何人都知道答案。还有什么我可能会失踪？
