采用POI创建Excel文件

import java.io.FileOutputStream;

import java.io.IOException;

public class ExcelCreate

{

public static void main(String[] args)throws IOException

{

HSSFWorkbook wb = new HSSFWorkbook();//建立新HSSFWorkbook对象

HSSFSheet sheet = wb.createSheet("new sheet");//建立新的sheet对象

// Create a row and put some cells in it. Rows are 0 based.

HSSFRow row = sheet.createRow((short)0);//建立新行

// Create a cell and put a value in it.

HSSFCell cell = row.createCell((short)0);//建立新cell

cell.setCellValue(1);//设置cell的整数类型的值

// Or do it on one line.

row.createCell((short)1).setCellValue(1.2);//设置cell浮点类型的值

row.createCell((short)2).setCellValue("test");//设置cell字符类型的值

row.createCell((short)3).setCellValue(true);//设置cell布尔类型的值

HSSFCellStyle cellStyle = wb.createCellStyle();//建立新的cell样式

Workbook workBook = new Workbook();

HSSFDataFormat hSSFDataFormat = new HSSFDataFormat(workBook);

cellStyle.setDataFormat(hSSFDataFormat.getFormat("m/d/yy h:mm"));//设置cell样式为定制的日期格式

HSSFCell dCell =row.createCell((short)4);

dCell.setCellValue(new Date());//设置cell为日期类型的值

dCell.setCellStyle(cellStyle); //设置该cell日期的显示格式

HSSFCell csCell =row.createCell((short)5);

csCell.setEncoding(HSSFCell.ENCODING_UTF_16);//设置cell编码解决中文高位字节截断

csCell.setCellValue("中文测试_Chinese Words Test");//设置中西文结合字符串

row.createCell((short)6).setCellType(HSSFCell.CELL_TYPE_ERROR);//建立错误cell

// Write the output to a file

FileOutputStream fileOut = new FileOutputStream("c:/workbook.xls");

wb.write(fileOut);

fileOut.close();
