Соединение с БД, используемое в методе службы, использующем только методы @Repository, без прямого использования DataSource. Класс обслуживания помечен @ Transactional.

Проблема: новое соединение запрашивается для каждого вызова метода, пока не будет использовано максимальное количество соединений, а затем пул застрял:

Итак, что я делаюнеправильно?

Причиной было аннотирование класса @Transactional, а другой метод, использованный событием server-sent из UI, возвращал Flux<ServerSentEvent<Data>>. Таким образом, @Transactional привело к тому, что соединение открывалось и никогда не закрывалось.

Удалить minimalIdle

MinimumIdle Это свойство контролирует минимальное количество незанятых соединений, которые HikariCP пытается поддерживать в пуле. Если число незанятых подключений падает ниже этого значения, а общее количество подключений в пуле меньше, чем MaximumPoolSize, HikariCP приложит все усилия для быстрого и эффективного добавления дополнительных подключений. Однако для максимальной производительности и реагирования на пиковые требования мы рекомендуем не устанавливать это значение и вместо этого разрешать HikariCP действовать как пул соединений фиксированного размера.

Удалить dataSourceClassName

Известно, что MySQL DataSource не работает из-за поддержки тайм-аута сети. Вместо этого используйте конфигурацию jdbcUrl.
