我正在为iOS游戏而团结。要解锁成就，我需要从我的C＃代码中访问“ Achievement.mm”文件：

    [DllImport("__Internal")]
    private static extern void

        //do common things
        LogUtils.log(logger, ex);
    }
    //do common things
}

//my clients call this
public void validateFromDb(DbValidationRequest dbValidationRequest){
    commonUtils.executeService(()-> dbValidationService.validate(dbValidationRequest));
}

//my clients call this
public void validateFromApi(ApiValidationRequest apiValidationRequest){
    commonUtils.executeService(()-> apiValidationService.validate(apiValidationRequest));
}

这是Java Spring应用程序的控制器。在executeService方法中，我传递了ServiceCaller接口的一个实例。我使用此方法从控制器调用所有服务。如果我使用 intelliJ IDEA …
