写入工作簿两次时org.apache.xmlbeans.impl.values.XmlValueDisconnectedException

Question

我正在创建一种从文件中写入和读取工作簿的方法,但是当我第二次调用此方法时.发生错误:org.apache.xmlbeans.impl.values.XmlValueDisconnectedException

public XSSFWorkbook GetUpdatedResult(XSSFWorkbook vmworkbookhelper) throws Exception
{
     this.vmWorkbookHelper2  = vmworkbookhelper;
    String tempName = UUID.randomUUID().toString()+".xlsx";
    File tempFile = new File(tempName);
    fileOut = new FileOutputStream(tempFile);
    this.vmWorkbookHelper2.write(fileOut);
    fileOut.close();
    vmworkbookhelper = new XSSFWorkbook(tempFile);
    if(tempFile.exists())
        tempFile.delete();
    return vmworkbookhelper;
}

同意Akokskis，编写两次导致问题的文件，但是您可以在编写之后尝试重新加载工作簿，这样便可以正常工作。例如

    FileOutputStream fileOut = new FileOutputStream("Workbook.xlsx");
    wb.write(fileOut);
    fileOut.close();
    wb = new XSSFWorkbook(new FileInputStream("Workbook.xlsx"));
