本博客介绍了如何使用Java创建一个Excel文件，用于展示销售信息报表，包括创建日期、微信号、姓名、电话等详细数据。

	public String excel() {
		try {
			String filename = "RKA_"
					+ DateFormatUtil.getFormatDate("yyyyMMddHHmmss");
			HttpServletResponse response = getResponse();
			OutputStream os = response.getOutputStream();// 取得输出流
			response.reset();
			response.setContentType("APPLICATION/X-MSDOWNLOAD;charset=utf-8");
			response.setCharacterEncoding("utf-8");
			response.setHeader(
					"Content-Disposition",
					new String(("attachment;filename=\"" + filename + ".xls\"")
							.getBytes("utf-8"), "utf-8"));
			response.setContentType("text/html");
			WritableWorkbook book = null;
			book = Workbook.createWorkbook(os); // 建立excel文件
			WritableSheet sheet = book.createSheet("销售信息", 10); // 创建一个工作表
			// -----------2--end
			// 生成表格题头
			Label labe0 = new Label(0, 0, "创建日期");
			Label labe1 = new Label(1, 0, "微信号");
			Label labe2 = new Label(2, 0, "姓名");
			Label labe3 = new Label(3, 0, "电话");
			Label labe4 = new Label(4, 0, "门店名称");
			Label labe5 = new Label(5, 0, "数量");
			Label labe6 = new Label(6, 0, "销售额");
			Label labe7 = new Label(7, 0, "大区");
			Label labe8 = new Label(8, 0, "标准分部");
			Label labe9 = new Label(9, 0, "渠道");
			Label labe10 = new Label(10, 0, "电脑型号");
			// 将生成的单元格添加到工作表中
			sheet.addCell(labe0);
			sheet.addCell(labe1);
			sheet.addCell(labe2);
			sheet.addCell(labe3);
			sheet.addCell(labe4);
			sheet.addCell(labe5);
			sheet.addCell(labe6);
			sheet.addCell(labe7);
			sheet.addCell(labe8);
			sheet.addCell(labe9);
			sheet.addCell(labe10);

			ISaleInfoService iSaleInfoService = (ISaleInfoService) AppContextUtil
					.getBean(RKACommon.saleInfo_Servcie);
			List<Saleinfo> saleinfoList =iSaleInfoService.getSaleInfo(RKACommon.sale_sqlQryByDate, getParams());
			if (saleinfoList != null || saleinfoList.size() > 0) {
				getAllInfoList(saleinfoList);
