Spring boot中下载文件名称中文变___________下划线了，请问如何处理？
@GetMapping("/download")@ResponseBodypublic ResponseEntity serveFile(@RequestParam String filename) throws IOException{ filename=new String(filename.getBytes(),"utf-8");//有没有这句话都不行 Resource file=new FileSystemResource("D:\\workspace\\idea_me\\demo\\upload-dir"+File.separator+ filename); HttpHeaders headers = new HttpHeaders(); headers.add("Cache-Control", "no-cache, no-store, must-revalidate"); headers.add("Content-Disposition", String.format("attachment; filename=\"%s\"", file.getFilename())); headers.add("Pragma", "no-cache"); headers.add("Expires", "0"); return ResponseEntity .ok() .headers(headers) .contentLength(file.contentLength()) .contentType(MediaType.parseMediaType("application/octet-stream;charset=utf-8"))//这里也是都不行 .body(new InputStreamResource(file.getInputStream()));}
