Question

我试图使用相同的视图来显示基于我从JSP中的按钮传递的参数的不同列表。

我需要的是：当用户点击按钮时，将调用相同的视图，但数据应显示在第二个列表中。（getPreviousYearReports（））

这是我的代码：

@RequestMapping(value = "/viewReports.do", method = {RequestMethod.GET , RequestMethod.POST})
public ModelAndView viewReports( @RequestParam final Integer storeNumber,
        final HttpServletRequest request) {
    ModelAndView view = getModelAndView("viewReports");

    List<StoreReport> reportsList;
    if(request.getParameter("previous") != null ) {
        reportsList = storeReportService.getPreviousYearReports(storeNumber);

    } else {
        reportsList = storeReportService.getReportsByStore(storeNumber);
    }
....
}

在我的JSP中。我添加了提交按钮来调用相同的视图映射

<button id="previous" name="previous" type="submit" class="btnFwd gradient smButtonStyling"
    onClick="window.location.href='/viewReports.do?storeNumber=${storeNumber}'">
View Previous Year Reports

我错过了通过“＆amp; previous”param
