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.
我正在使用XSSFCellStyle来实现这一目标,但它对我不起作用.
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);
解决方法
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();
