excel正常导出了，但是报了个错，不知道是什么原因，各位大佬帮忙看看
public Object exportDayData(@Param("spotCode")String spotCode, @Param("date")String date, HttpServletResponse resp){
OutputStream out = resp.getOutputStream();
HSSFWorkbook wk = new HSSFWorkbook();
resp.addHeader("content-type", "application/shlnd.ms-excel;charset=utf-8");
resp.addHeader("content-disposition", "attachment; filename=flowdata.xls");
HSSFSheet sheet = wk.createSheet("测试数据");
HSSFRow row = sheet.createRow(0);
HSSFCell cell = row.createCell(0);
cell.setCellValue("序号");
cell = row.createCell(1);
cell.setCellValue("时间");
cell = row.createCell(2);
cell.setCellValue("测试1");
cell = row.createCell(3);
cell.setCellValue("测试2");
cell = row.createCell(4);
cell.setCellValue("测试3");
List<Record> historyDayData = historyFlowDataService.findHistoryDayData(spotCode, date);
for (int i = 0; i < historyDayData.size(); i++) {
HSSFRow row1 = sheet.createRow(i + 1);
Record record = historyDayData.get(i);
//创建单元格设值
row1.createCell(0).setCellValue(i+1);
row1.createCell(1).setCellValue(record.getString("date"));
row1.createCell(2).setCellValue(record.getInt("realtime_number"));
row1.createCell(3).setCellValue(record.getInt("total_number"));
row1.createCell(4).setCellValue(record.getString("level"));
}
wk.write(out);
