POI 操作office2007

XSSFWorkbook与HSSFWorkbook的差别

api基本一致 操作office2007部分代码如下:

Java代码


public class Excel

//读excel文档

public void readExcel(String sheetName)

{

XSSFSheet sheet = getSheet(sheetName);

if(sheet != null)

{

for(Iterator<Row> i = sheet.rowIterator(); i.hasNext();)

continue;

//System.out.println(row.getRowNum() + "="+row.getCell(0));

for(Iterator<Cell> j = row.cellIterator(); j.hasNext();)

{

//Cell cell = j.next();

XSSFCell cell = (XSSFCell) j.next();

if(cell == null)

continue;

System.out.print(getCellValue(cell) + " ");

}

System.out.println();

}

}

else

{

System.out.println("没有找到工作表");

}

}

//加载工作薄

private XSSFWorkbook getXSSFWorkBook()

{

XSSFWorkbook workbook = null;

try

{

String path = System.getProperty("user.dir") + System.getProperty("file.separator")+"doc"+ System.getProperty("file.separator")+"ExcelDoc.xlsx";

workbook = new XSSFWorkbook(new FileInputStream(path));

}

catch (Exception e)

{

e.printStackTrace();

}

return workbook;

}

//根据名字取工作表Sheet

private XSSFSheet getSheet(String sheetName)

{

return this.getXSSFWorkBook().getSheet(sheetName);

}

//判断Cell单元格的类型。

private String getCellValue(Cell cell)

{

Object result = null;

switch(cell.getCellType())

{

case Cell.CELL_TYPE_STRING:

result = cell.getStringCellValue();

break;

case Cell.CELL_TYPE_NUMERIC:

if(DateUtil.isCellInternalDateFormatted(cell))

result = cell.getDateCellValue();

else

result = cell.getNumericCellValue();

break;

break;

case Cell.CELL_TYPE_ERROR:

result = cell.getErrorCellValue();

break;

case Cell.CELL_TYPE_BOOLEAN:

result = cell.getBooleanCellValue();

break;

default:

result = "NULL";

break;

}

return result.toString();

}

//生成excel文件

public void createExcelDoc()

{

String path = System.getProperty("user.dir") + System.getProperty("file.separator")+"doc"+ System.getProperty("file.separator")+"creatExcelDoc.xlsx";

try

{

FileOutputStream outStream = new FileOutputStream(path);

XSSFWorkbook workbook = new XSSFWorkbook();

XSSFSheet sheet = workbook.createSheet("first");

sheet.autoSizeColumn(0);

XSSFRow row = sheet.createRow(0);

row.createCell(0).setCellValue("Name");

row.createCell(1).setCellValue(2.2);

//helper.createDataFormat() 得到一个DataFormat实例

/*CreationHelper helper = workbook.getCreationHelper();

CellStyle dateStyle = workbook.createCellStyle();

dateStyle.setDataFormat(helper.createDataFormat().getFormat("yyyy-MM-dd hh:mm:ss"));

Cell c = row.createCell(2);

c.setCellValue(new Date());

c.setCellStyle(dateStyle);*/

//XSSF....方法

XSSFCell cell = row.createCell(2);

XSSFCellStyle style = workbook.createCellStyle();

XSSFCreationHelper h = workbook.getCreationHelper();

style.setDataFormat(h.createDataFormat().getFormat("yyyy-MM-dd"));

style.setAlignment(XSSFCellStyle.VERTICAL_CENTER);

cell.setCellStyle(style);

cell.setCellValue(new Date());

//设置第n单元格的宽度，自动

sheet.autoSizeColumn(2);

workbook.write(outStream);

System.out.println("create finished!!");

}

catch (Exception e)

{

}

}
