springboot中加载Excel模板下载问题

• 在项目中导入商品数据时需要提供一个商品的模板下载，在resources目录中存放模板
• 需要在pom.xml中添加build

            
                src/main/resources
                
                    **/*.*
                
                false
            
        

如果没有添加会导致编译的时候不会把Excel编译到classes目录中

 @GetMapping("/downloadTemplete")
    public void downloadTemplete(HttpServletResponse response) throws UnsupportedEncodingException {
        response.setContentType("application/application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
        response.setHeader("Content-Disposition",
                "attachment;filename=" + URLEncoder.encode("设备导入模板", "UTF-8") + ".xlsx");
        response.setHeader("Access-Control-Expose-Headers", "Content-disposition");
        try {
            Resource resource = new ClassPathResource("excel/template.xlsx");   //静态文件位置
            InputStream inputStream = resource.getInputStream();
            byte[] buffer = new byte[inputStream.available()];   //问题所在
            inputStream.read(buffer);
            inputStream.close();
            OutputStream outputStream = new BufferedOutputStream(response.getOutputStream());
            outputStream.write(buffer);
            outputStream.flush();
            outputStream.close();
        } catch (Exception e) {
            e.printStackTrace();
            response.setStatus(404);
        }
    }
