Question

在我的系统中，当用户选择一个学生组（例如CS Year1）时，应该为该学生组加载时间表视图。有人可以告诉我该如何做。谢谢

我创建了时间表视图（所有视图都一样），还选择了带有下拉菜单和“提交”按钮的时间表页面。

时间表控制器

@Controller
public class TimeTableController {
    @Autowired
    private TimeTableDAO timeTableDAO;

    @Autowired
    private SubjectDAO subjectDAO;

    @Autowired
    private StudentGroupDAO studentGroupDAO;


    @RequestMapping("/timeTable")
    public String viewHomePage(Model model){
        TimeTable timeTable =new TimeTable();
        model.addAttribute("timeTable",timeTable);

        List<StudentGroup> studentGroupDetail = studentGroupDAO.findAll();
        model.addAttribute("studentGroups", studentGroupDetail);
        return "timeTable";
    }



    @RequestMapping("/timeTable/select")
    public String addTimeTable(Model model){
        TimeTable timeTable =new TimeTable();
        model.addAttribute("timeTable",timeTable);

        List<Subject> subjectDetail = subjectDAO.findAll();
        model.addAttribute("subjects", subjectDetail);


        List<StudentGroup> studentGroupDetail = studentGroupDAO.findAll();
        model.addAttribute("studentGroups",studentGroupDetail);

        return "timeTableView";
    }

    @RequestMapping(value="/timeTable/save",method= RequestMethod.POST)
    public String saveTimeTable(@ModelAttribute("timeTable") TimeTable timeTable){
        timeTableDAO.save(timeTable);
        return  "redirect:/timeTable";
    }

    @RequestMapping("/timeTable/edit/{id}")
    public ModelAndView updateTimeTable(@PathVariable(name="id")Long id){
        ModelAndView mav=new ModelAndView(("updateTimeTable"));

        TimeTable timeTable = timeTableDAO.findById(id);
        mav.addObject("timeTable",timeTable);

        List<Subject> subjectDetail = subjectDAO.findAll();
        mav.addObject("subjects", subjectDetail);
        List<StudentGroup> studentGroupDetail = studentGroupDAO.findAll();
        mav.addObject("studentGroups",studentGroupDetail);

        return  mav;
    }

    @RequestMapping("/timeTable/delete/{id}")
    public String deleteProduct(@PathVariable(name="id") Long id){
        timeTableDAO.delete(id);
        return  "redirect:/timeTable";
    }
}

根据下拉菜单的选择加载页面
