我在創建新的xlsx文件時遇到了XSSFWorkbook apis問題。XSSFWorkbook問題 - 創建新文件
場景:我的gui菜單中有一個菜單項「New File」,它從流中創建新的xlsx文件。第一次當我點擊菜單項「New File」時,出現新的對話框,我給出新的xlsx文件的名稱,並創建新的文件。但是當我第二次點擊這個菜單項「新文件」時,新的xlsx不會被創建。
//Code snippet
File newOpenXLSFile;
public XSSFWorkbook newPtrIrWorkBook;
newPtrIrStream = this.getClass().getResourceAsStream ("/org/ama/defect/prevention/templates/MainTemplate.xlsx");
private void jMenuItem1ActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
logger.debug("You choose to create new PTR/IR file");
int returnVal = jFileChooser4.showDialog(this, "New PTR/IR Data File");
if (returnVal == JFileChooser.APPROVE_OPTION) {
newOpenXLSFile = jFileChooser4.getSelectedFile();
logger.debug("file path " + newOpenXLSFile);
try {
logger.debug("For second time, I am stopped here:");
//newPtrIrWorkBook = new HSSFWorkbook(newPtrIrPFS, true); //copying extract into Excel file
newPtrIrWorkBook = new XSSFWorkbook(newPtrIrStream);
logger.debug("New File..." + newOpenXLSFile.getPath());
FileOutputStream out = new FileOutputStream(newOpenXLSFile);
newPtrIrWorkBook.write(out);
out.close();
} catch (Exception e) {
e.getMessage();
}
} else {
logger.debug("New file dialogue cancelled by user.");
}
}
對於第二次,我想它會阻止這裏的代碼語句:
logger.debug("For second time, I am stopped here:");
//newPtrIrWorkBook = new HSSFWorkbook(newPtrIrPFS, true);//copying extract into
//Excel file
---> newPtrIrWorkBook = new XSSFWorkbook(newPtrIrStream); <---

能否請你幫我解決這個問題?但是,HSSFWorkbook
(對於xls文件)沒有問題。
java.io.IOException: Stream closed
看來問題是::
非常感謝,

你有沒有嘗試在調試器中運行它,所以你可以檢查確定事件鎖定的位置? – Gagravarr
