Весенняя сессия с одновременным обновлением сессий jdbc

-1

соединение (id: 358250360) было получено 14: 11: 55,420 и выпущено в 14: 11: 55,471, которое охватывало 51 мс, и в течение этой 51-секундной весенней сессии выполнялось 7 операций обновления. Это вызвано только доступом к URL-адресу. если много пользователей одновременно подключены к сети, могут возникнуть проблемы с подключением в пуле. Интересно, это факт весенней сессии с jdbc или я пропустил некоторые конфигурации.Весенняя сессия с одновременным обновлением сессий jdbc

Это совершенно нормальный сценарий.

Во время реализации поддержки Spring JDBC было сделано много усилий, чтобы сделать взаимодействие с базовой базой данных максимально эффективным, однако, если ваше приложение будет использоваться с высокой степенью совместимости со многими пользователями, я бы посоветовал вам рассмотреть возможность использования более совершенной технологии, такой как Redis или Hazelcast, для поддержки вашего SessionRepository.

'JdbcOperationsSessionRepository', похоже, распознает явно« setAttribute (K, V) », поэтому« save' 'updatedCount» будет действительным. Я использовал карту как V return из 'getAttribute (K)' и изменил ее без 'setAttribute'. Однако этот класс репозитория не сохраняет его. Это конфликтует с поведением нормального «HttpSession» (где я могу обновить его в следующий раз при сеансе сеанса). – Tiina

Реализации Spring Session 'SessionRepository' сохраняют сеанс во внешнем хранилище данных, поэтому, естественно, экземпляры сеансов, возвращенные из репо, фактически являются копиями, которые необходимо сохранить при изменении. Диспетчер сеансов по умолчанию для сервлета обычно находится в памяти, например Tomcat, что означает, что вы имеете дело с одним и тем же объектом сеанса все время, чтобы вы могли избежать описанного вами подхода. Это не противоречит «HttpSession», поскольку такое поведение AFAIK не документировано нигде в API. Вы столкнулись с такой же ситуацией, используя постоянный диспетчер сеансов Tomcat. –

'updatedCount' в' JdbcOperationSessionRepository' должно фактически обрабатывать «обновленное» значение как обновленное, теперь оно явно выполняет это с предварительным условием. – Tiina
