Apache POI-如何使用选项保护工作表？

在Apache POI 3.9中，可以通过启用锁定功能来使用XSSF
Sheet保护。甚至您可以留下一些未锁定的excel对象，以防万一下面我遗漏了未锁定的excel对象（即文本框）而其余部分被锁定的情况。

 private static void lockAll(Sheet s, XSSFWorkbook workbookx){    String password= "abcd";    byte[] pwdBytes = null;    try {        pwdBytes  = Hex.depreHex(password.toCharArray());    } catch (DeprerException e) {        e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.    }    XSSFSheet sheet = ((XSSFSheet)s);    removePivot(s,workbookx);    sheet.lockDeleteColumns();    sheet.lockDeleteRows();    sheet.lockFormatCells();    sheet.lockFormatColumns();    sheet.lockFormatRows();    sheet.lockInsertColumns();    sheet.lockInsertRows();    sheet.getCTWorksheet().getSheetProtection().setPassword(pwdBytes);    for(byte pwdChar :pwdBytes){        System.out.println(">>> Sheet protected with '" + pwdChar + "'");    }    sheet.enableLocking();    workbookx.lockStructure();}
