Я писал программу для тестирования ServletContainerInitializer. Проблема в том, что сам ServletContainerInitializer работает правильно, а ServletContainerInitializer.onStartup называется «ssd», но ServletContext.addServlet не регистрирует мой сервлет и, следовательно, метод init не вызывается. пожалуйста, проверьте журнал ниже
