いくつかの単体テストで徹底的にテストしたデータベース バックエンドがあります。コントローラーは次のようになります。
@RequestMapping(value = "/create", method = RequestMethod.POST, produces = "application/json", headers = "content-type=application/json")
public @ResponseBody UserDTO createUser(@RequestBody UserDTO user)
{
UserEntity userEntity = service.add(user);
return mappingUser(userEntity);
}
単体テストは次のようになります。
@Test
public void testCreateUser() throws Exception
{
UserDTO userDto = createUserDto();
String url = BASE_URL + "/rest/users/create";
UserDTO newUserDto = restTemplate
.postForObject(url, userDto, UserDTO.class, new Object[]{});
}
単体テストがうまく機能し、実際の Web サービスが正しく呼び出され、データがデータベースに入れられることを確認しました。
今、私は SmartGWT RestDataSource を使用しています。RestDataSource を正しく構成して、リクエスト本文で新しいユーザーを渡し、新しいオブジェクトを返すようにしています。データを本文の JSON として送信し、この呼び出しから JSON を返したいと考えています。そのため、データソースと一致するようにコントローラー自体を変更する必要があるかもしれません。
以下は、RestDataSource を拡張する AbstractDataSource です。

そして、AbstractRestDataSource を拡張する UserDataSource は次のとおりです。

}
UserDTO を JSON として requestBody に入れる方法がわかれば、すべての問題が解決したと思います。知っておくべき追加情報については、Spring 3.2 と springmvc-servlet.xml ファイルで構成された Jackson Message Converters を使用しています。
ある時点で、すべてのデータが URL に追加されるのを確認しましたが、データがパラメーターとして URL に含まれているのではなく、リクエストの本文に含まれていればよかったと思います。SO、これが可能かどうか、およびその方法を知る必要があります。
助けてくれてありがとう!!!
