Java实现Excel导入导出

Excel源代码，导入导出各种工具类 org.apache.poi poi org.apache.poi poi-scratchpad 代码实例： String path = ""; byte[] bytes; vo.setCurrentPage(0); vo.setPageSize(Integer.MAX_VALUE); List list = stockOrderController.exportShOutOrderDetail(vo); Map empinfo = new TreeMap(); int index = 1; empinfo.put(index++, new Object[]{"销售单号", "销售时间", "会员", "商品总额", "来源", "商品名称/属性", "数量", "单价"}); for (ShOutOrderDetail item : list) { empinfo.put(index++, new Object[]{ item.getOutOrderNo(), DateUtil.SDF.format(item.getOutTime()), item.getNickName()+"/"+item.getMobile(), String.valueOf(item.getStockPrice().multiply(new BigDecimal(item.getStockAmount()))), "01".equals(item.getSalesSource()) ? "线上订单" : "线下订单", item.getGoodsNameAttrs(), String.valueOf(item.getStockAmount()), String.valueOf(item.getStockPrice()) }); } try { bytes = ExcelUtils.simpleExcel(empinfo, "销售单信息"); MultipartFile multipartFile = new MultipartFile(); multipartFile.setData(bytes); multipartFile.setOriginalFilename("ShOutOrderDetailExport.xls"); path = fastDFSClientController.uploadFile(multipartFile); } catch (Exception e) { logger.error("出库单信息导出失败 : {}", e.getMessage(), e); return "fail"; } logger.info("出库单信息导出结束，path:{}", path); return path;
