我试图在从数据库获取后在 jsp 中的表中显示学生数据
学生 Servlet
ArrayList student = new ArrayList();
String selectSQL = "SELECT studentname from student";
while (rs.next()) {
studentname = rs.getString(1);
student.add(studentname);
}
request.setAttribute("student", student);
request.getRequestDispatcher("home.jsp").include(request, response);
home.jsp
<%
ArrayList List = new ArrayList();
String student = (String) request.getAttribute("student");
List.add(student);
Iterator<String> itr = List.iterator();
while (itr.hasNext()) {
%>
<table>
<tr>
<th>Students</th>
</tr>
<tr>
<td><%=itr%>
</td>
</tr>
</table>
<%
}
%>
home.jsp 部分有问题。非常感谢任何帮助。
