RabbitMQ Не удалось объявить очередь, и слушатель не может получить очередь на сервере

Question

RabbitMQ Не удалось объявить очередь, и слушатель не может получить очередь на сервере

У меня есть приложение rabbitmq для весенней загрузки, в котором я должен отправить объект Employee в очередь. Затем я настроил приложение для прослушивания. Сделайте некоторую обработку на объекте работника и поместите этот объект в очередь обратного вызова.

Для этого я создал ниже объекты в моем приложении.

Создан ConnectionFactory.
Создан объект RabbitAdmin с использованием ConnectionFactory.
Очередь запросов.
Очередь звонков.
Прямой обмен.
Привязка очереди запросов.
Привязка очереди обратного вызова.
MessageConverter.
Объект RabbitTemplate.
И, наконец, объект SimpleMessageListenerContainer.

Мои файлы приложений выглядят как показано ниже.

Кто-нибудь может помочь мне решить мою проблему? Насколько я понимаю, когда создается объект SimpleMessageListenerContainer, очередь обратного вызова не создается на сервере rabbitmq. Я попытался объявить очередь, используя объект RabbitAdmin, но затем выполнение останавливается и ничего не происходит. Эта проблема не была, когда я объявлял очередь в виртуальном хосте по умолчанию. Но когда я добавил виртуальный хост foo, все внезапно перестало работать. Вы можете повторить эту проблему, используя приведенный выше код. Я вставил весь свой код. Пожалуйста, дайте мне знать, если что-то еще будет опубликовано.

Интересно, что даже если я получаю это исключение, мое приложение работает и работает. Это означает, что каким-то образом моя очередь обратного вызова создается, и объект SimpleMessageListenerContainer получает очередь. Я где-то читал, что при создании очереди мой объект SimpleMessageListenerContainer будет его слушать.

Пожалуйста, помогите мне решить эту проблему.

Эта проблема не была, когда я объявлял очередь в виртуальном хосте по умолчанию. Но когда я добавил виртуальный хост foo, все внезапно перестало работать.

Имеет ли пользователь, который обращается к новому виртуальному хосту configure разрешения? Настроить разрешения, необходимые для объявления очередей.

RabbitAdmin требуется для объявления очередей / привязок; контейнер только делает пассивное объявление, чтобы проверить наличие очереди.

container.start();

Ты не должен start() контейнер в определении бина. Контекст приложения будет делать это после того, как контекст приложения будет полностью построен, если контейнер autoStartUp является true (дефолт).

Из ваших журналов ясно, что контейнер запускается слишком рано - до того, как были объявлены другие компоненты (admin, queue и т. Д.).
