nc 刷新时调动风车界面

1.总体思路 nc 刷新的方法就是继承刷新默认的class 类，然后在action类中 获取页面的id 通过id来查询数据，将查到的数据用实体的数据接收，然后塞到modle中显示即可。

需要注意的有两点 一时 注意sql的优化，比如多个id查询 最好不要用for 循环遍历去一个一个查 最好是用in来查询，还有一个需要注意 用in查询 字段最好不要超过3000.

在查询过程中，由于数据量比较大，需要调用风车界面 ，在数据没查完 需要调用它 ，调完了 就结束。

具体代码如下：

package nc.ui.am.actions.batch;


import java.awt.Container;
import java.awt.event.ActionEvent;
