使用apache poi使列只读

I am using apache-poi for generating the excel file. I need to make the 4th column read-only and the remaining 2 columns will be editable by the user.

我正在使用apache-poi生成excel文件。我需要将第4列设为只读,其余2列将由用户编辑。

I am using XSSFCellStyle to achieve this but it's not working for me.

我正在使用XSSFCellStyle实现这一点,但它不适合我。

The entire code is:

整个代码是:

Map<String, XSSFCellStyle> styles = new HashMap<String, XSSFCellStyle>();

XSSFCellStyle style5 = wb.createCellStyle();
XSSFFont headerFont = wb.createFont();
headerFont.setBold(true);
style5.setFillForegroundColor(IndexedColors.GREY_25_PERCENT.getIndex());
style5.setFillPattern(XSSFCellStyle.SOLID_FOREGROUND);
style5.setFont(headerFont);
style5.setLocked(true); // this line does not get executed.
styles.put("header", style5);

You have to protect the whole sheet and unlock the cells which should be editable:

您必须保护整个工作表并解锁应该可编辑的单元格:

String file = "c:\\poitest.xlsx";
FileOutputStream outputStream = new FileOutputStream(file);
Workbook wb = new XSSFWorkbook();

CellStyle unlockedCellStyle = wb.createCellStyle();
unlockedCellStyle.setLocked(false);

Sheet sheet = wb.createSheet();
sheet.protectSheet("password");
Row row = sheet.createRow(0);
Cell cell = row.createCell(0);
cell.setCellValue("TEST");
cell.setCellStyle(unlockedCellStyle);

wb.write(outputStream);
outputStream.close();
