Spring 4：按ResponseEntity或其他方式返回对象列表？

Question

我需要根据ResponseEntity返回一个对象列表。我知道，我目前只是列表中的最后一个对象，但我需要一个完整的列表。想法？

@RequestMapping(path = "findAllPhotosByPhotoAlbumTitle", method = RequestMethod.GET)
@ResponseBody
public ResponseEntity<InputStreamResource> findAllPhotosByPhotoAlbumTitle(@PathVariable(value = "albumTitle") String albumTitle) throws IOException {

final List<Photo> allPhotosByPhotoAlbumTitle = photoService.findAllPhotosByPhotoAlbumTitle(albumTitle);

    ResponseEntity<InputStreamResource> body = null;

    for (Photo photo : allPhotosByPhotoAlbumTitle) {
        body = ResponseEntity.ok()
                .contentLength(photo.getMultipartFile().getSize())
                .contentType(MediaType.parseMediaType(photo.getMultipartFile().getContentType()))
                .body(new InputStreamResource(photo.getMultipartFile().getInputStream()));
    }
    return body;
}
