xlsx格式的写入的数据量据说有百万级,结合实际需要该格式。
public static void main(String[] args) throws Exception { OutputStream outputStreamExcel = null; File tmpFile = new File("E:" + File.separator + "file_route" + File.separator + "detail.xlsx"); if (!tmpFile.getParentFile().exists()) { tmpFile.getParentFile().mkdirs();//创建目录 } if(!tmpFile.exists()) { tmpFile.createNewFile();//创建文件 } Workbook workbook = null; workbook = new XSSFWorkbook();//创建Workbook对象(excel的文档对象) Sheet sheet1 = workbook.createSheet("Sheet1");// 建建sheet对象(excel的表单) // 设置单元格字体 Font headerFont = workbook.createFont(); // 字体 headerFont.setFontHeightInPoints((short)14); headerFont.setFontName("黑体"); // 设置单元格边框及颜色 CellStyle style = workbook.createCellStyle(); style.setBorderBottom((short)1); style.setBorderLeft((short)1); style.setBorderRight((short)1); style.setBorderTop((short)1); style.setWrapText(true); Row row = sheet1.createRow(0); row.createCell(0).setCellValue("序号"); row.createCell(1).setCellValue("编号"); row.createCell(2).setCellValue("支付订单号"); row.createCell(3).setCellValue("商品订单号"); Row row1 = sheet1.createRow(1); row1.createCell(0).setCellValue("10001"); row1.createCell(1).setCellValue("90001"); row1.createCell(2).setCellValue("1000000000012"); row1.createCell(3).setCellValue("9000000000099"); outputStreamExcel = new FileOutputStream(tmpFile); workbook.write(outputStreamExcel); outputStreamExcel.flush(); outputStreamExcel.close(); }
导入相应的jar包后,直接运行即可。
