通过方法'graphQLWebsocketServlet表示的不满意依赖性

Question

当我尝试使用Spring Boot构建graphql时，出现以下问题

    public function __construct(ValidityEndHandler $validityEndHandler, InventoryRepository $repository)
    {
        $this->validityEndHandler = $validityEndHandler;            
        $this->repository = $repository;
        parent::__construct();
    }

    protected function execute(InputInterface $input, OutputInterface $output)
    {
        $inventory = $this->repository->yourRequest();
        // pass the mailer service you need directly to ValidityHandler and send only $inventory as a parameter
        $this->validityEndHandler->sendReminderMail($inventory);      
        $output->writeln('Emails werden gesendet');

    }
