使用了bean属性方法
<br>
<br>
用户名：
<%=user.getUserName() %>
<br>
<br>
密码：
<%=user.getPassWord() %>
<br>
<br>
年龄：
<%=user.getAge() %>
<br>
<hr>
使用getProperty
<br><br>
用户名：
<jsp:getProperty name="user" property="userName"/>
<br><br>
密码：
<jsp:getProperty property="password" name="user"/>
<br><br>
年龄：
<jsp:getProperty property="age" name="user"/>
<br><br>
</body>
</html>
