修改用户功能

先根据userID获取 其他属性，然后进行修改



<%
List<User> lu = (List<User>)request.getAttribute("userlist");

for(User u : lu)
{
    out.print(u+"【<a href='getOne?userID="+u.getUserID()+"'>修改</a>】【<a href='deleteUser?userID="+u.getUserID()+"'>删除</a>】<br>");
}

%>

<!-- 查询单个 -->

<action name="getOne"  class="action.UserAction" method="getOne" >

<result name="fail" >/WEB-INF/pages/fail.jsp</result>
<result >/WEB-INF/pages/xiugaiUser.jsp</result>

</action>

<!-- 修改 -->

<action name="xiugaiUser"  class="action.UserAction" method="xiugaiUser" >

<result name="fail" >/WEB-INF/pages/fail.jsp</result>
<result >index.jsp</result>

</action>
