Spring MVC 文件下载时候 发现IE不支持

@RequestMapping("download")
    public ResponseEntity<byte[]> download(Long fileKey) throws IOException {
        HttpHeaders headers = new HttpHeaders();
        String fileName=new String(massMessage.getFileName().getBytes("UTF-8"),"iso-8859-1");
        headers.setContentDispositionFormData("attachment", fileName);
        headers.setContentType(MediaType.APPLICATION_OCTET_STREAM);
        byte[] data = new byte[2];//要下载的数据流
        return new ResponseEntity<byte[]>(data, headers, HttpStatus.CREATED);
    }

下载时提示：

下载时提示ie无法打开该站点，请求的站点不可用或找不到

类似信息

修改为下面的就OK了，主要是HttpStatus.CREATED修改为HttpStatus.OK

原因是IE 不支持201的状态码，修改为200就行了

@RequestMapping("download")
    public ResponseEntity<byte[]> download(Long fileKey) throws IOException {
        HttpHeaders headers = new HttpHeaders();
        String fileName=new String(massMessage.getFileName().getBytes("UTF-8"),"iso-8859-1");
        headers.setContentDispositionFormData("attachment", fileName);
        headers.setContentType(MediaType.APPLICATION_OCTET_STREAM);
        byte[] data = new byte[2];//要下载的数据流
        return new ResponseEntity<byte[]>(data, headers, HttpStatus.OK);
    }
