注釈と私の方法のうちのいずれかを設定するたびに、私は次のスタックトレース(ロードされたページ上のBoNTない!)を取得:

私のコードのルックスこのように:クラスで
は実装DeadboltHandler
@Override
public CompletionStage<Optional<? extends Subject>> getSubject(Context elContext) {
return CompletableFuture.supplyAsync(
() -> {
try {
return Optional.ofNullable(da.getUser(Integer.parseInt(elContext.session().get("userId"))));
} catch (Exception e) {
e.printStackTrace();
return null;
}
});
}
コンストラクタ持っている:
DataAccess da;
DeadboltSecureHandler(Database db){
da = new DataAccess(db);
}
とクラスで私が台無しにした内容の任意のアイデアHandlerCache
@Inject
public DeadboltHandlerCache(Database db){
DeadboltHandler defaultHandler = new DeadboltSecureHandler(db);
handlers.put(HandlerKeys.DEFAULT.key, defaultHandler);
}
@Override
public DeadboltHandler apply(final String key){
return handlers.get(key);
}
@Override
public DeadboltHandler get(){
return defaultHandler;
}
を実装しますか?
