<!DOCTYPE struts PUBLIC

<package name="user" namespace="/nsfw" extends="struts-default">
    <action name="user_*" class="cn.itcast.nsfw.user.action.UserAction" method="{1}">

问题一：action 的数据不能传到jsp
浏览器输入http://localhost:8080/itcastTax/nsfw/user_listUI.action访问listUI.jsp的结果如下：

1. 不能将数据库的user显示出来
2.从Debug可以看到action已经从数据库的数据取到listuser

问题二：jsp的数据不能传到action
在listUI.jsp点击新建进入addUI.jsp，输入数据点击保存，在数据库的user并没有添加。

Answer 1

你贴的jsp文件的代码好像是User类的代码吧
