Я хочу управлять несколькими данными с помощью встроенных функций приложений и доступа к ним с помощью JNDI. Я использую Spring boot с данными Spring JPA. Я могу настроить application.properties для одиночного источника данных. Но, пытаясь сделать то же самое для mutiple datasource, я получаю исключение при запуске приложения.Несколько баз данных + JNDI с данными Spring JPA для инициализации
Исключение при запуске сервера Tomcat: -

Я также остановил memcached и попытался, после этого я получаю журнал сбоев подключения при запуске приложения.
Не повезло. Все еще получаю ошибку то же самое. Добавил его к свойствам. Я добавляю все свойства для обоих экземпляров сущности (customerEntityManager и employeeeEntityManager). – Manu
Вызвано: net.spy.memcached.OperationTimeoutException: операция Mutate отключена, не удалось изменить счетчик [validator.validatorCache.HibernateCacheTimestamperMemcachedImpl: timestamp] – Manu
Ну, аналогичная проблема с тем, о которой вы упоминали последний, описана [здесь] (http: /stackoverflow.com/questions/21410829/increment-times-out-set-always-succeeds-after-retry). Попробуйте исключить memcached из вашего проекта для запуска. Я понял, что у вас опять нет такой же ошибки ('NoSuchBeanDefinitionException: не указан bean с именем« entityManagerFactory »), но только этот новый? – rikica
