java 下载excel模板

1.我们把需要下载的的excel 模板放在resource下面,模板要什么样子自己修改excel就好

1.接下来我们读取需要下载的excel模板就好

String fileName="test";
ClassPathResource classPathResource = new ClassPathResource("template/eventAndProperty.xlsx");

// 判断下载哪个excel

// 初始化流
InputStream inputStream = null;
OutputStream outputStream = null;
try {
    inputStream = classPathResource.getInputStream();
    response.setContentType("application/x-msdownload");
    outputStream = response.getOutputStream();
    response.addHeader("Content-Disposition", "attachment; filename=" + new String(fileName.getBytes(),"iso-8859-1"));
   // 执行流操作
    IoUtils.copy(inputStream,outputStream);
} catch (IOException e) {
    log.error(e.getMessage());
}finally {
    // 关流
    IOUtils.closeQuietly(inputStream);
    IOUtils.closeQuietly(outputStream);
}
