使excel表只读

我想使用Apache POI HSSF创build后只读Excel表。 我怎样才能做到这一点？

详细的描述可以在这里find： http : //systeminetwork.com/article/locking-cells-hssf

基本上你必须分配你的单元格与CellStyle.setLocked(true)自定义CellStyle.setLocked(true)

嗨Gaurav，这里是完整的工作代码：

 HSSFWorkbook workbook = new HSSFWorkbook（）;
 HSSFSheet sheet = workbook.createSheet（“sheet1”）;
 / *密码所需的密码才能生效* /
 sheet.protectSheet（ “secretPassword的”）;

 / *单元格样式locking* /
 CellStyle lockedCellStyle = workbook.createCellStyle（）;
 lockedCellStyle.setLocked（真）;
 / *可编辑单元格的单元格样式* /
 CellStyle unlockedCellStyle = workbook.createCellStyle（）;
 unlockedCellStyle.setLocked（假）;

 / *将被locking的单元* /
 Cell lockedCell = sheet.createRow（0）.createCell（0）;
 lockedCell.setCellValue（“嗨，我被locking...”）;
 lockedCell.setCellStyle（lockedCellStyle）;

 / *解锁的单元格* /
 Cell unlockedCell = sheet.createRow（1）.createCell（0）;
 unlockedCell.setCellValue（“只编辑我...”）;
 unlockedCell.setCellStyle（unlockedCellStyle）;

 OutputStream out = new FileOutputStream（“sample.xls”）;
 workbook.write（下）;
了out.flush（）;
 out.close（）;

这里是一些testing代码，使特定的单元格只读 。 根据你在@Thomas Weber的回答中的评论。

这将在单元格中设置初始值，然后使用数据约束来确保用户不能在Excel中修改固定值。 试试看。

 HSSFWorkbook workBook = new HSSFWorkbook (); HSSFSheet sheet1 = workBook.createSheet(); HSSFRow row1 = sheet1.createRow(10); HSSFCell cell1 = row1.createCell(0); cell1.setCellValue("text: The new line which should be locked"); // SETTING INITIAL VALUE HSSFCell displayNameCell = cell1; String[] displayNameList = new String[]{"text: The new line which should be locked"}; //ADDING SAME VALUE INTO A STRING ARRAY AS THE RESTRICTED VALUE DVConstraint displayNameConstraint = DVConstraint.createExplicitListConstraint(displayNameList); CellRangeAddressList displayNameCellRange = new CellRangeAddressList(displayNameCell.getRowIndex(),displayNameCell.getRowIndex(),displayNameCell.getColumnIndex(),displayNameCell.getColumnIndex()); HSSFDataValidation displayNameValidation = new HSSFDataValidation(displayNameCellRange,displayNameConstraint); displayNameValidation.createErrorBox("Not Applicable","Cannot change the value"); displayNameValidation.setSuppressDropDownArrow(true); displayNameCell.getSheet().addValidationData(displayNameValidation); // Write the output to a file FileOutputStream fileOut1 = new FileOutputStream("D:\\book.xls"); workBook.write(fileOut1); fileOut1.close();

 new File("/path/to/file.xls").setReadOnly();
