使用poi低版本(poi-3.0.1)导出Excel整理

最近使用POI低版本（poi-3.0.1-FINAL-20070705.jar）导出数据到Excel，有很多新版本的函数都不可用，整理如下。

 

创建work book:

HSSFWorkbook wb = new HSSFWorkbook();

 

创建sheet页：
HSSFSheet sheet = wb.createSheet("sheet页标题");

 

设置打印预览：

// 设置水平居中

sheet.setHorizontallyCenter(true);

 

//设置边距 （1=2.5cm）
sheet.setMargin(HSSFSheet.TopMargin, (double) 1);

sheet.setMargin(HSSFSheet.LeftMargin, (double) 1);
sheet.setMargin(HSSFSheet.BottomMargin, (double) 1);
sheet.setMargin(HSSFSheet.RightMargin, (double) 1);

HSSFPrintSetup ps = sheet.getPrintSetup();
ps.setPaperSize(HSSFPrintSetup.A4_PAPERSIZE);

// 设置打印朝向
ps.setLandscape(true);// 设置横向打印
ps.setLandscape(false);// 设置纵向打印

ps.setScale((short) 80); // 设置打印缩放比例
ps.setHeaderMargin((double) 0.5);// 设置页眉打印范围
ps.setFooterMargin((double) 0.5);// 设置页脚打印范围

//插入图片：
String imagePath = DOCSettingConst.REPORT_REPORT_IMAGE_PATH;
imagePath = DOCSettingConst.REPORT_TEMPLATE_PATH_ABSOLUTE + imagePath;

 

ByteArrayOutputStream byteArrayOut = new ByteArrayOutputStream();
BufferedImage bufferImg = ImageIO.read(new File(imagePath));
ImageIO.write(bufferImg, "jpg", byteArrayOut);

HSSFPatriarch patriarch = sheet.createDrawingPatriarch();
HSSFClientAnchor anchor = new HSSFClientAnchor(0, 0, 850, 0, (short) 0, 0, (short) 3, 7);
HSSFPicture pic = patriarch.createPicture(anchor, wb.addPicture(byteArrayOut.toByteArray(),
            HSSFWorkbook.PICTURE_TYPE_JPEG));

 

//创建cell

HSSFRow row = sheet.getRow(3);
HSSFCell cell36 = row.getCell((short) 6);
if (cell36 == null) {
     cell36 = row.createCell((short) 6);
}

if (arrivalUsedTugs != null) {

//设置数字cell:
      cell36 .setCellType(HSSFCell.CELL_TYPE_NUMERIC);
      cell36 .setCellValue(arrivalUsedTugs);
} else {

//设置字符串cell:
     cell36 .setCellType(HSSFCell.CELL_TYPE_STRING);
     cell36 .setCellValue(new HSSFRichTextString(""));
}

 

//合并单元格：
Region mergeRegion3638 = new Region(3, (short) 6, 3, (short) 8);
sheet.addMergedRegion(mergeRegion3638);

 

//设置显示样式：

HSSFCellStyle style = wb.createCellStyle();
               
style.setBorderBottom(HSSFCellStyle.BORDER_MEDIUM);   
style.setBorderLeft(HSSFCellStyle.BORDER_MEDIUM);   
style.setBorderRight(HSSFCellStyle.BORDER_MEDIUM);      
style.setBorderTop(HSSFCellStyle.BORDER_MEDIUM);             

style.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);
style.setFillForegroundColor(HSSFColor.PALE_BLUE.index);
style.setAlignment(HSSFCellStyle.ALIGN_LEFT);
style.setVerticalAlignment(HSSFCellStyle.ALIGN_CENTER);

 

HSSFFont font = wb.createFont();       
font.setFontHeightInPoints((short) 24);        
font.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD);

style.setFont(font);

 

 

//导出到Excel:

String excelPath = "....";

String fileName = "....";

SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHmmss");
String currentDate = sdf.format(new Date());
StringBuffer sb = new StringBuffer();
sb.append(excelPath);
sb.append(fileName);
sb.append(currentDate);
sb.append(".xls");
pathName = sb.toString();
export(pathName, wb);

 

public static void export(String fileName, HSSFWorkbook wb) throws Exception {
        FileOutputStream fileOut = null;
        try {         
            File excelFile = new File(fileName);
            if (excelFile.exists()) {
                excelFile.delete();
            }

            excelFile.createNewFile();

            fileOut = new FileOutputStream(excelFile);
            wb.write(fileOut);
        } catch (Exception e) {
            throw e;
        } finally {
            if (fileOut != null) {
                try {
                    fileOut.close();
                } catch (Exception e) {
                   
                }
            }
        }
    }
