再次
，我一直在想，...
更重要的是，如果你的目标是测验文档在测验系统中打开为测验参与者分发的文件，然后他们打开它，然后他们可以用答案填写表格（例如Pdf表格）并签名（或自动签名为您的登录名）并提交/保存使系统具有所有有效/合法测试/问答文件的文件，可以查询和法官/年级，我认为这是如何去：

SEEE：
在这里，您可以在JquisFileCooser的compojnet相关（incude使用注射例如界面春天，例如。
你然后（尽管也可以仅仅指刚财产inection用豆）
主代码
@autowire
IQuizFileChooser
这将导致这个文件选择的内容或处理
然后你就可以赶上在主代码中选择的文件事件将会像
private void newBean11PropertyChange(java.beans.PropertyChangeEvent evt) {//GEN-FIRST:event_newBean11PropertyChange
// TODO add your handling code here:
}//GEN-LAST:event_newBean11PropertyChange
凡EVT通讯员您的活动
，并填写要显示的容器内
保存时，那么你使用一些的FileWriter写有正确的ID名称正确的目录
您只需连接易于应用的型号记录
GOTIT？
所以最后你只需要这一切
@autowire Iquizzfilechooser
@autowire Containner //如果你想做到这一点， 您可以立即根据你想要去的地方运行如果，其他是注射或如果你想添加更多的其他东西取决于你然后
很酷的权利？
