使用apache poi api java锁定excel工作簿

Question

I have to lock a workbook while reading and writing a row.

Is there way to accomplish this using Apache POI API without protecting and password option?.

As a suggestion, paste some of your code that could help others to understand and solve the problem.

As far as I know you can't "lock" the hole Workbook but one thing you can try is to apply a CellStyle to cells you want to protect while reading or writing.

Workbook wb = new XSSFWorkbook();

CellStyle lockedCellStyle = wb.createCellStyle();
lockedCellStyle.setLocked(true);

Sheet sheet = wb.createSheet();
// .... Create rows and cells as needed

// When Writing or reading
Cell cell = getCellsToLockWithAnyMethod();
cell.setCellStyle(lockedCellStyle);
