要求
编程实现用户注册，信息包括姓名、密码、年龄。提交后注册页面显示信息，分别通过request、bean属性、getProperty动作获取。
使用bean属性获取时需要建立java类如下：
UserRegisterBean类：
package bean;
public class UserRegisterBean {
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
private String name;
private int pass;
private int age;
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public int getPass() {
return pass;
}
public void setPass(int pass) {
this.pass = pass;
}
}

使用request获取：<br>
姓名：<%=name%><br>
密码：<%=pass%><br>
年龄：<%=age%><br>
<hr>
使用bean属性获取：<br>
<%--<jsp:getProperty name="user" property="name"/>--%>
<jsp:useBean id="user" scope="page" class="bean.UserRegisterBean" >
<jsp:setProperty name="user" property="*"/>
</jsp:useBean>
姓名：<%=user.getName()%><br>

使用getProperty动作：<br>
密码：<jsp:getProperty name="user" property="pass"/><br>
