SSH开发输出少内容,发现是插入数据的问题，看看问题在哪儿？

Question

最近学习了浪曦风中叶张老师的SSH项目，自己做的时候发现输出少内容，控制台没有报错，结果如下：
List User
序号 姓名 密码 年龄 更新 删除
1 e update delete
开始把User的name属性是username的时候，姓名有输出，密码和年龄没有输出，年龄显示为0（那时候age的类型为int）。
发现先在数据库中输入数据可以得到结果，就是在jsp页面输入数据到数据库的过程中有问题,名字和年龄在数据库中均为空。
请高手看看是哪儿的问题，谢谢！

下面为主要代码：

index.jsp
[code="java"]

SaveUser/s:a

ListUser/s:a
[/code]

save.jsp(内容部分国际化)
[code="java"]
/s:textfield
/s:textfield
/s:textfield
/s:submit
/s:form[/code]

list.jsp
[code="java"]

      <s:iterator value="#request.list" id="us">
          <tr>
              <td><s:property value="#us.id"/></td>
              <td><s:property value="#us.name"/></td>
              <td><s:property value="#us.password"/></td>
              <td><s:property value="#us.age"/></td>
              <td><s:a href="updatePUser.action?user.id=%{#us.id}">update</s:a></td>
              <td><s:a href="deleteUser.action?user.id=%{#us.id}">delete</s:a></td>
          </tr>
      </s:iterator>
