Question

为什么 jstl c set 不显示问题

servlet代码： UserDAO dao = new UserDAOJdbc(); User us = dao.getUser(new Integer(request.getParameter("uid"))); request.setAttribute("user.edit", us); request.getRequestDispatcher("/reg.jsp").forward(request, response);jsp代码：<c:set var="us" value="${requestScope['user.edit']}"/> <td height="30" width="99"><div align="right">用户名:</div></td> <td width="291" ><label> <input type="text" name="username" value="${us.username}" /> </label></td>

Answer 1

${requestScope['user.edit']} 改成 ${user.edit}试试
