如何在spring boot restful应用中响应pbf文件？

@RestController
public class PbfController {

    @GetMapping(value = "/pbf", produces = "application/octet-stream")
    public ResponseEntity<byte[]> getPbfFile() throws IOException {
        // 读取PBF文件内容
        Path pbfFilePath = Paths.get("path/to/pbf/file.pbf");
        byte[] pbfFileContent = Files.readAllBytes(pbfFilePath);

        // 构建响应头
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_OCTET_STREAM);
        headers.setContentDispositionFormData("attachment", "file.pbf");

        // 返回响应
        return ResponseEntity.ok()
                .headers(headers)
                .body(pbfFileContent);
    }
}
