，我一直在想，...
更重要的是，如果你的目標是測驗文檔在測驗系統中打開爲測驗參與者分發的文件，然後他們打開它，然後他們可以用答案填寫表格（例如Pdf表格）並簽名（或自動簽名爲您的登錄名）並提交/保存使系統具有所有有效/合法測試/問答文件的文件，可以查詢和法官/年級，我認爲這是如何去：

SEEE：
在這裏，您可以在JquisFileCooser的compojnet相關（incude使用注射例如界面春天，例如。
你然後（儘管也可以僅僅指剛財產inection用豆）
主代碼
@autowire
IQuizFileChooser
這將導致這個文件選擇的內容或處理
然後你就可以趕上在主代碼中選擇的文件事件將會像
private void newBean11PropertyChange(java.beans.PropertyChangeEvent evt) {//GEN-FIRST:event_newBean11PropertyChange
// TODO add your handling code here:
}//GEN-LAST:event_newBean11PropertyChange
凡EVT通訊員您的活動
，並填寫要顯示的容器內
保存時，那麼你使用一些的FileWriter寫有正確的ID名稱正確的目錄
您只需連接易於應用的型號記錄
GOTIT？
所以最後你只需要這一切
@autowire Iquizzfilechooser
@autowire Containner //如果你想做到這一點， 您可以立即根據你想要去的地方運行如果，其他是注射或如果你想添加更多的其他東西取決於你然後
很酷的權利？
