私はすべての記事を返すリクエストハンドラメソッド "listAll"を持っています。このメソッドを呼び出すと記事リストが返されますが、anglejs側でこのリターンにアクセスすると、ユーザー情報が含まれません。たとえば、article.user.nameは情報を返しませんが、他の記事フィールドにアクセスできます。私のエンティティ、anglejsのスクリプトとコントローラは以下の通りです。Spring RestとAngularjsでエンティティのオブジェクト情報を取得する方法は？
@RequestMapping(method = RequestMethod.GET, produces = "application/json")
public ResponseEntity<?> listAll(@RequestParam int page, Locale locale) {
return createListAllResponse(page, locale);
}
Angularjsスクリプト：
それは返す "data.articles [i]を.user" 次のスクリプトで定義されていない：
