如何使用apache poi将2016 excel复制到另一个(包括公式,单元格样式和日期格式).Below是我尝试过的代码。它复制文件,但不复制单元格样式。此外,单元格类型方法显示为已弃用,这是他们的新方法吗?此外,我需要使用XSSF而不是HSSF进行尝试。
public void copy(String origFileName,String newFileName) {
// TODO Auto-generated method stub
try {
BufferedInputStream bis = new BufferedInputStream(new FileInputStream(origFileName));
XSSFWorkbook origWorkbook = new XSSFWorkbook(bis);
XSSFWorkbook copyWorkbook = new XSSFWorkbook();
XSSFSheet origSheet = null;
XSSFRow origRow = null;
XSSFCell origCell = null;
XSSFSheet copySheet = null;
XSSFRow copyRow = null;
XSSFCell copyCell = null;
int origSheets = origWorkbook.getNumberOfSheets();
int fCell = 0;
int lCell = 0;
int fRow = 0;
int lRow = 0;
for (int iSheet = 0; iSheet < origSheets; iSheet++) {
origSheet = origWorkbook.getSheetAt(iSheet);
if (origSheet != null) {
copySheet = copyWorkbook.createSheet(origSheet.getSheetName());
fRow = origSheet.getFirstRowNum();
lRow = origSheet.getLastRowNum();
for (int iRow = fRow; iRow <= lRow; iRow++) {
origRow = origSheet.getRow(iRow);
copyRow = copySheet.createRow(iRow);
if (origRow != null) {
fCell = origRow.getFirstCellNum();
lCell = origRow.getLastCellNum();
for (int iCell = fCell; iCell < lCell; iCell++) {
origCell = origRow.getCell(iCell);
copyCell = copyRow.createCell(iCell);
if (origCell != null) {
CellStyle cellStyle = setCellStyle(copyWorkbook, origCell);
copyCell.setCellType(origCell.getCellType());
switch (origCell.getCellType()) {
case XSSFCell.CELL_TYPE_BLANK:
copyCell.setCellValue("");
break;
case XSSFCell.CELL_TYPE_BOOLEAN:
copyCell.setCellValue(origCell.getBooleanCellValue());
break;
case XSSFCell.CELL_TYPE_ERROR:
copyCell.setCellErrorValue(origCell.getErrorCellValue());
break;
case XSSFCell.CELL_TYPE_FORMULA:
copyCell.setCellFormula(origCell.getCellFormula());
break;
case XSSFCell.CELL_TYPE_NUMERIC:
copyCell.setCellValue(origCell.getNumericCellValue());
break;
case XSSFCell.CELL_TYPE_STRING:
copyCell.setCellValue(origCell.getStringCellValue());
break;
default:
copyCell.setCellFormula(origCell.getCellFormula());
}
copyCell.setCellStyle(cellStyle);
}
}
}
}
}
}
bis.close();
BufferedOutputStream bos;
bos = new BufferedOutputStream(new FileOutputStream(newFileName, true));
copyWorkbook.write(bos);
bos.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
private CellStyle setCellStyle(XSSFWorkbook copyWorkbook, XSSFCell origCell) {
CellStyle cellStyle = copyWorkbook.createCellStyle();
//cellStyle.setFillBackgroundColor(IndexedColors.AQUA.getIndex());
cellStyle.setFillForegroundColor(origCell.getCellStyle().getFillForegroundColor());
cellStyle.setFont(origCell.getCellStyle().getFont());
cellStyle.setBottomBorderColor(origCell.getCellStyle().getBottomBorderColor());
cellStyle.setLeftBorderColor(origCell.getCellStyle().getLeftBorderColor());
cellStyle.setLocked(origCell.getCellStyle().getLocked());
cellStyle.setQuotePrefixed(origCell.getCellStyle().getQuotePrefixed());
cellStyle.setRightBorderColor(origCell.getCellStyle().getRightBorderColor());
cellStyle.setRotation(origCell.getCellStyle().getRotation());
cellStyle.setShrinkToFit(origCell.getCellStyle().getShrinkToFit());
cellStyle.setTopBorderColor(origCell.getCellStyle().getTopBorderColor());
cellStyle.setVerticalAlignment(origCell.getCellStyle().getVerticalAlignmentEnum());
cellStyle.setWrapText(origCell.getCellStyle().getWrapText());
cellStyle.setHidden(origCell.getCellStyle().getHidden());
cellStyle.setIndention(origCell.getCellStyle().getIndention());
cellStyle.setAlignment(origCell.getCellStyle().getAlignmentEnum());
cellStyle.setBorderBottom(origCell.getCellStyle().getBorderBottomEnum());
cellStyle.setBorderLeft(origCell.getCellStyle().getBorderLeftEnum());
cellStyle.setBorderRight(origCell.getCellStyle().getBorderRightEnum());
cellStyle.setBorderTop(origCell.getCellStyle().getBorderTopEnum());
cellStyle.setFillPattern(origCell.getCellStyle().getFillPatternEnum());
return cellStyle;
}
答案 0 :(得分:0)
要复制样式,请参阅:Copy a XSSF/HSSF-Cells into a new XSSFWorkbook
我修改了你的代码并且工作正常
有关处理单元格类型的新方法,请参阅修改后的代码。
