代码如下：
@RequestMapping("/export")
public void export(HttpServletRequest request, HttpServletResponse response) {
response.setContentType("text/html");
Workbook wb;
File file = null;
try {
// 模板路径
String xlsTemplatePath = "";
Date date = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("MMdd");
String fileName = "";
String time = sdf.format(date);
xlsTemplatePath = webDownloadPath + "//report.xlsx";//webDownloadPath在yml中配置
fileName = "导出模板_" + time;
file = ResourceUtils.getFile(xlsTemplatePath);
// 获取文件输入流
InputStream inputStream = new FileInputStream(file);
Workbook wbPartModule = null;
if(xlsTemplatePath.endsWith(".xlsx")){
wbPartModule = new XSSFWorkbook(inputStream);
}else if(xlsTemplatePath.endsWith(".xls")){
wbPartModule = new HSSFWorkbook(inputStream);
}
inputStream.close();
wb = wbPartModule;
// 设置response参数，可以打开下载页面
response.reset();
// xlsx 下载
response.setContentType("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
// xls 下载
response.addHeader("Content-Disposition", "attachment;filename=" + new String(fileName.getBytes("gb2312"), "ISO-8859-1") + ".xlsx");
// 导出excel
OutputStream out = response.getOutputStream();
ExcelUtil.exportExcel(wb, out);
} catch (Exception e) {
e.printStackTrace();
}
}
yml配置
