1. 实体类字段上加 @Excel(name = "xxx"), 表示要导出的字段

    @Excel(name = "订单号")private String orderNo;

2. controller (get请求)

    /*** 导出订单列表*/@ApiOperation("导出订单列表")@GetMapping("/export")public void export(HttpServletResponse response, LsOrder lsOrder){List<LsOrder> list = lsOrderService.selectLsOrderList(lsOrder);ExcelUtil<LsOrder> util = new ExcelUtil<LsOrder>(LsOrder.class);util.exportExcel(response, list, "订单数据");}

3. 调用exportExcel方法, 输出到浏览器 (导出的所有文件名都是export.xlsx, 不是我想要的)

    /*** 对list数据源将其里面的数据导入到excel表单* * @return 结果*/public void exportExcel(HttpServletResponse response){try{writeSheet();wb.write(response.getOutputStream());}catch (Exception e){log.error("导出Excel异常{}", e.getMessage());}finally{IOUtils.closeQuietly(wb);}}

4. 修改exportExcel方法, 浏览器输出文件, 动态文件名

新增一行

response.setHeader("Content-Disposition", "attachment;filename=" + java.net.URLEncoder.encode("文件名称", "utf-8") + ".xlsx");

 

 

    /*** 对list数据源将其里面的数据导入到excel表单* * @return 结果*/public void exportExcel(HttpServletResponse response){try{response.setHeader("Content-Disposition", "attachment;filename=" + java.net.URLEncoder.encode(sheetName+"-"+System.currentTimeMillis(), "utf-8") + ".xlsx");writeSheet();wb.write(response.getOutputStream());}catch (Exception e){log.error("导出Excel异常{}", e.getMessage());}finally{IOUtils.closeQuietly(wb);}}
