action
private Question q;
private String question;
private String answer;
public String execute() {
AdminDao adminDao = new AdminDaoImpl();
try {
q.setQuestion(question);
q.setAnswer(answer);
adminDao.add(q);
return "success";
} catch (Exception e) {
e.printStackTrace();
return "fail";

<body style="text-align:center;background-color:00ffee;">
<form action="addquestion.action" method="post">
<table>
<tr style="color:blue;">
<td>题目</td>
<td>答案</td>
</tr>
<tr>
