采用POI创建Excel文件

import org.apache.poi.hssf.model.Workbook;
import org.apache.poi.hssf.usermodel.*;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Date;

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();
  
 }
}
