Я обновляю некоторые Spring Boot Applications с запросами JPA. Все работает нормально, кроме одного указанного c вида запросов (findByJsonNode). Это работало нормально в более ранних версиях, но после обновления мои компоненты не могут быть созданы.
Это работало нормально до Spring Boot 2.1.4.RELEASE и Spring Cloud версии Greenwich.SR1, но при обновлении до Spring Boot 2.2.4.RELEASE и Spring Cloud версия Hoxton.RELEASE, Spring не может создать мой bean-репозиторий.
