如何安排JSP页面？

Question

我有一个JSP页面作为task.jsp。因此，我希望每年（即每年3月）仅显示一次此页面。

我不知道如何安排时间。请帮我。以下是我的示例控制器代码：

@RequestMapping(
    value = "task.htm",
    method = RequestMethod.GET
)

public ModelAndView taskPost(@ModelAttribute("task") Task task, HttpServletRequest request) {
    ModelAndView model = new ModelAndView("task");
    //do something
    return model;
}

Answer 1

您可以抛出ResponseStatusException：

@RequestMapping(value = "task.htm", method = RequestMethod.GET)
public ModelAndView taskPost(@ModelAttribute("task") Task task,HttpServletRequest request {
    if(LocalDate.now().getMonth() != Month.MARCH) {
        throw new ResponseStatusException(HttpStatus.NOT_FOUND, "Unable to find resource");
    }

    ModelAndView model = new ModelAndView("task");
    //do something
    return model;
}
