尝试设计一个小仪表板 - 我在2个mysql表中准备好了数据。我甚至有DAO和控制器工作正常。我试图在一个jsp上显示这些表...我的doGet（）看起来像这样 -
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String forward = "";
String action = request.getParameter("action");
forward = LIST_CASEDETAIL;
request.setAttribute("casedetails", dao.getDailyBoard());
request.setAttribute("caseweekly", dao.getWeeklyBoard());
RequestDispatcher view = request.getRequestDispatcher(forward);
view.forward(request, response);
}
问题1 - 这是允许的吗？ 问题2 - 如果是 - 它不起作用。我的jsp正在DailyBoard上展示。我需要了解我在这里做错了什么。非常感谢您提供所有帮助。以下是来自Controller，DAO＆amp;的代码。 JSP

答案 0 :(得分：0)
对于JSP中的每周，你输错了名字，它应该是
Time.now同样在你的DAO中，我认为你将caseNo分配了两次，另一个应该是fileNo，对吗？
答案 1 :(得分：0)
尝试添加页面名称jsp：
if __name__ == "__main__":
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "core.settings")
from django.core.management import execute_from_command_line
load_env()
execute_from_command_line(sys.argv)
因为前锋需要 String forward = "some_name.jsp";
。
并尝试替换它：
page jsp使用：
<c:forEach items="${caseweekls}" var="casewdetail">
