Sping Boot -下载zip文件

Question

当我尝试下载zip文件时，它下载成功，但下载的文件名为"download.zip"，与@GetMapping Annotation的value参数相匹配。

@GetMapping(value = "/download", produces = "application/zip")
    public @ResponseBody byte[] getFile() throws IOException {
        InputStream inputStream = new FileInputStream(downloadDir + "check.zip");
        return IOUtils.toByteArray(inputStream);
    }

如何设置下载文件的具体名称？提前感谢您的回复！

Answer 1

您应该将其作为响应头返回：content-disposition : "attachment; filename=check.zip"

-->

    @GetMapping(value = "/download", produces = "application/zip")
    public @ResponseBody byte[] getFile(HttpServletResponse response) throws IOException {
        InputStream inputStream = new FileInputStream(downloadDir + "check.zip");
        response.setHeader("Content-Disposition", "attachment; filename=check.zip");
        return IOUtils.toByteArray(inputStream);
    }
