Spring 3.0 レスト、休止状態 3、および Android 4 を使用しています。db テーブルにユーザーを追加しようとすると、動作が停止します。Android と Spring 3.1 を使用してポストに設定されたオブジェクトは常に null です。これは、Spring Controller のサーバー側にあります。

@Transactional(readOnly = false)
@RequestMapping(value = "/user/add/", method = RequestMethod.POST, 
        headers = "Accept=application/json,text/html,application/xhtml+xml,application/xml",
        consumes ="{MediaType.APPLICATION_JSON_VALUE}", produces = "{MediaType.APPLICATION_JSON_VALUE}")
public @ResponseBody
User registerUser(@ModelAttribute("user") User user, HttpServletResponse response) throws IOException {

    return userService.saveUser(user);
}

ここで、ユーザーは常に null であり、もちろん db に挿入されます..null 値。

Androidからこれは私のオブジェクトを送信する方法です:

try {
        RestTemplate restTemplate = new RestTemplate();
        GenericEntityWithJson getEntityHeader = new GenericEntityWithJson();
        HttpEntity<Taxi> entityHeader = getEntityHeader
                .getHttpEntityWithJsonHeaders(user);
        response = restTemplate.postForObject(url, entityHeader, User.class);
    } catch (Exception e) {
        System.out.println("register error: " + e.getMessage());
    }

投稿アクションの前に、私のオブジェクトuserには値があります。クライアント側でエラーを受信しません。サーバー側に直接送信されますが、null に到達します。@RequestBody を使用してみましたが、コントローラーメソッドに入ることさえありません。以前にこれに遭遇したことがありますか?どんなアイデアでも素晴らしいでしょう。以前にこのエラーが発生した人はいますか? 現時点では、もう何を試すべきか本当にわかりません。ありがとうございました!
