不能直接通过路径来获取

这个是一个下载导出文件的操作

java 复制代码

@GetMapping(value = "/export/all")
public void exportAll(HttpServletResponse response, LaylineListReq req) throws IOException {
    // 从类路径下获取 Excel 文件资源
    ClassPathResource classPathResource = new ClassPathResource("template/放线表主数据导入系统模板_template.xlsx");
    // 获取文件输入流
    InputStream inputStream = classPathResource.getInputStream();

    String fileName = "xxx"

    fileName = URLEncoder.encode(fileName, "UTF-8").replaceAll("\\+", "%20");
    response.setCharacterEncoding("UTF-8");
    response.setContentType("application/vnd.ms-excel");
    response.setHeader("Content-Disposition", "attachment;filename=" + fileName + ".xlsx");
    response.setHeader("Access-Control-Expose-Headers", "Content-Disposition");

    EasyExcel.write(response.getOutputStream())
            .withTemplate(inputStream)
            .sheet()
            .doFill(list);
}

获取填充模版也需要先转换成 inputStream，不能照着官方的写法读取文件，下面是官方的写法，可以对比一下
