<body>
<jsp:useBean id="user" scope="application" class="JavaBean.UserRegisterBean" />
<jsp:setProperty name="user" property="*" />
注册成功：
<hr/>
使用Bean属性方法：
<br/>
用户名:<%=user.getUsername() %>
<br/>
密码：<%=user.getPassword() %>
<br/>
年龄：<%=user.getAge() %>
<hr/>
使用getProperty动作:
<br/>
用户名:<jsp:getProperty property="username" name="user"/>
<br/>
密码：<jsp:getProperty property="password" name="user"/>
<br/>
年龄：<jsp:getProperty property="age" name="user"/>
<hr/>
</body>
</html>
分别用 JavaBean 和 getProperty 两种方法处理获得注册用户的信息，并输出.
<jsp:useBean id="user" class="JavaBean.UserRegisterBean" />
等价于：
<%
UserRegisterBean user =new UserRegisterBean();
%>
