1、遍历workbook

2、得到列和单元格

代码

HSSFRow row = sheet.getRow(i);
HSSFCell cell = row.getCell((short) j);

3、设�|�sheet名称和单元格内容��Z��?/strong>

代码

wb.setSheetName(n, "中文",HSSFCell.ENCODING_UTF_16);

cell.setEncoding((short) 1);

cell.setCellValue("中文");

4、单元格内容未公式或数��|��可以�q�样��d��

代码

cell.setCellType(HSSFCell.CELL_TYPE_NUMERIC);

cell.getNumericCellValue()

5、设�|�列宽、行�?/strong>

代码

sheet.setColumnWidth((short)column,(short)width);

row.setHeight((short)height);

6、添加区域，合�ƈ单元�?/strong>

代码

Region region = new Region((short)rowFrom,(short)columnFrom,(short)rowTo,(short)columnTo);

sheet.addMergedRegion(region);

//得到所有区�?

sheet.getNumMergedRegions()

7、常用方�?/strong>
�Ҏ��单元��g��同属性返回字�W�串数�?

代码

public String getCellStringValue(HSSFCell cell) {

        String cellValue = "";

        switch (cell.getCellType()) {

        case HSSFCell.CELL_TYPE_STRING:

            cellValue = cell.getStringCellValue();

            if(cellValue.trim().equals("")||cellValue.trim().length()<=0)

                cellValue=" ";

            break;

        case HSSFCell.CELL_TYPE_NUMERIC:

            cellValue = String.valueOf(cell.getNumericCellValue());

            break;

        case HSSFCell.CELL_TYPE_FORMULA:

            cell.setCellType(HSSFCell.CELL_TYPE_NUMERIC);

            cellValue = String.valueOf(cell.getNumericCellValue());

            break;

        case HSSFCell.CELL_TYPE_BLANK:

            cellValue=" ";

            break;

        case HSSFCell.CELL_TYPE_BOOLEAN:

            break;

        case HSSFCell.CELL_TYPE_ERROR:

            break;

        default:

            break;

        }

        return cellValue;

    }

8、常用单元格�Ҏ��格式

虚线HSSFCellStyle.BORDER_DOTTED
实线HSSFCellStyle.BORDER_THIN

代码

public static HSSFCellStyle getCellStyle(short type)

    {

       HSSFWorkbook wb = new HSSFWorkbook();

       HSSFCellStyle style = wb.createCellStyle();

       style.setBorderBottom(type);//下边�?nbsp;

        style.setBorderLeft(type);//左边�?nbsp;

        style.setBorderRight(type);//双��?nbsp;

        style.setBorderTop(type);//上边�?nbsp;

       return style;

    }

9、设�|�字体和内容位置

代码

HSSFFont f  = wb.createFont();

f.setFontHeightInPoints((short) 11);//字号

f.setBoldweight(HSSFFont.BOLDWEIGHT_NORMAL);//加粗

style.setFont(f);

style.setAlignment(HSSFCellStyle.ALIGN_CENTER);//左右居中

style.setVerticalAlignment(HSSFCellStyle.VERTICAL_CENTER);//上下居中

style.setRotation(short rotation);//单元格内容的旋�{的角�?

HSSFDataFormat df = wb.createDataFormat();

style1.setDataFormat(df.getFormat("0.00%"));//讄��单元格数据格�?

cell.setCellFormula(string);//�l�单元格讑օ��?

style.setRotation(short rotation);//单元格内容的旋�{的角�?

cell.setCellStyle(style);

10、插入图�?/strong>
论坛里看到的

代码

//先把读进来的囄��攑ֈ�一个ByteArrayOutputStream中，以便产生ByteArray

      ByteArrayOutputStream byteArrayOut = new ByteArrayOutputStream();

      BufferedImage bufferImg = ImageIO.read(new File("ok.jpg"));

      ImageIO.write(bufferImg,"jpg",byteArrayOut);

//读进一个excel模版

FileInputStream fos = new FileInputStream(filePathName+"/stencil.xlt");

fs = new POIFSFileSystem(fos);

//创徏一个工作薄

HSSFWorkbook wb = new HSSFWorkbook(fs);

HSSFSheet sheet = wb.getSheetAt(0);

HSSFPatriarch patriarch = sheet.createDrawingPatriarch();

HSSFClientAnchor anchor = new HSSFClientAnchor(0,0,1023,255,(short) 0,0,(short)10,10);

patriarch.createPicture(anchor , wb.addPicture(byteArrayOut.toByteArray(),HSSFWorkbook.PICTURE_TYPE_JPEG));

POI操作Excel文档�Q�基��（转）

liaojiyong — Wed, 14 Nov 2007 14:26:00 GMT

关键�? poi

一�Q�POI��?

Jakarta POI 是apache的子��目�Q�目标是处理ole2对象。它提供了一�l�操�U�Windows文档的Java API

目前比较成熟的是HSSF接口�Q�处理MS Excel�Q?7-2002�Q�对象。它不象我们仅仅是用csv生成的没有格式的可以由Excel转换的东西，而是真正的Excel对象�Q�你可以控制一些属性如sheet,cell�{�等�?

二．HSSF概况

HSSF 是Horrible SpreadSheet Format的羃写，也即“讨厌的电子表格格�?#8221;�?也许HSSF的名字有�Ҏ��E�，��本质而言它是一个非�怸�肃、正规的API。通过HSSF�Q�你可以用纯Java代码来读取、写入、修改Excel文�g�?

HSSF ��取操作提供了两类API�Q�usermodel和eventusermodel�Q�即“用户模型”�?#8220;事�g-用户模型”。前者很好理解，后者比较抽象，但操作效率要高得多�?

三．开始编�?

1 �Q?准备工作

要求:JDK 1.4+POI开发包

可以�?http://www.apache.org/dyn/closer.cgi/jakarta/poi/ 最新的POI工具�?

2 �Q?EXCEL �l�构

HSSFWorkbook excell 文档对象介绍
HSSFSheet excell的表�?
HSSFRow excell的行
HSSFCell excell的格子单�?
HSSFFont excell字体
HSSFName 名称
HSSFDataFormat 日期格式
在poi1.7中才有以�?��：
HSSFHeader sheet�?
HSSFFooter sheet��?
和这个样�?
HSSFCellStyle cell样式
辅助操作包括
HSSFDateUtil 日期
HSSFPrintSetup 打印
HSSFErrorConstants 错误信息�?

3 �Q�具体用法实�?�Q�采�?usermodel �Q?

如何读Excel

��d��Excel文�g�Ӟ��首先生成一个POIFSFileSystem对象�Q�由POIFSFileSystem对象构造一个HSSFWorkbook�Q�该HSSFWorkbook对象��׃��表了Excel文档。下面代码读取上面生成的Excel文�g写入的消息字�Ԍ��

代码

POIFSFileSystem fs=newPOIFSFileSystem(new FileInputStream("d:\test.xls"));
HSSFWorkbook 　wb = new HSSFWorkbook(fs);
　　} catch (IOException e) {
　　e.printStackTrace();
　　}
　　HSSFSheet sheet = wb.getSheetAt(0);
　　HSSFRow row = sheet.getRow(0);
　　HSSFCell cell = row.getCell((short) 0);
　　String msg = cell.getStringCellValue();

如何写excel�Q?

��excel的第一个表单第一行的�W�一个单元格的值写�?#8220;a test”�?

代码

POIFSFileSystem fs =new POIFSFileSystem(new FileInputStream("workbook.xls"));
HSSFWorkbook wb = new HSSFWorkbook(fs);
HSSFSheet sheet = wb.getSheetAt(0);
HSSFRow row = sheet.getRow(0);
HSSFCell cell = row.getCell((short)0);
cell.setCellValue("a test");
// Write the output to a file
FileOutputStream fileOut = new FileOutputStream("workbook.xls");
wb.write(fileOut);
fileOut.close();

4 �Q?可参考文�?

POI 主页�Q�http://jakarta.apache.org/poi/�Q?

初学者如何快速上手��用POI HSSF

http://jakarta.apache.org/poi/hssf/quick-guide.html �?

代码例子 http://blog.java-cn.com/user1/6749/archives/2005/18347.html

里面有很多例子代码，可以很方便上手�?

四．使用心得

POI HSSF 的usermodel包把Excel文�g映射成我们熟悉的�l�构�Q�诸如Workbook、Sheet、Row、Cell�{�，它把整个�l�构以一�l�对象的形式保存在内存之中，便于理解�Q�操作方便，基本上能够满��x��们的要求�Q�所以说�q�个一个不错的选择�?/p>
