__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：
- 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。
2.debug看到UserAaction.add()方法取到的user为空：
关键代码如下：

public User() {
super();
