В моем случае я разработал N веб-приложений, каждое из которых использует общий кэш Infinispan и JGroups в качестве транспортного уровня.
Когда веб-приложение запускается, оно создает объект cachemanager и регистрирует его в JNDI сервера приложений. Следующая запущенная веб-приложение проверяет JNDI и, если находит менеджер кеша, уже связанный другим веб-приложением, использует его с помощью простых вызовов поиска.
Таким образом, первое веб-приложение, создающее экземпляр диспетчера распределенного кеша, должно быть первым действующим лицом, запускающим канал jgroups, то есть координатором.
Проблема возникает, когда:
Мне нужно обновить все веб-приложения путем горячего развертывания с использованием новых войн.
Я аннулирую все войны, уже запущенные на сервере приложений.
Я развертываю новые войны
Все войны успешно развернуты
Через 1 миллисекунду после развертывания балансировщик нагрузки перенаправляет все входящие клиентские запросы в новые доступные службы веб-приложений.
новое вызванное веб-приложение не находит ни одного менеджера кеша, связанного с JNDI, поэтому создает новый. Таким образом, он создает новый канал.
В этот момент я получаю это исключение:
