jdbc와의 스프링 세션이 동시에 업데이트 세션 테이블

-1

연결 (id : 358250360)은 14 : 11 : 55,420으로 획득되어 14 : 11 : 55,471에 출시되었으며 51ms를 커버했으며이 51ms 스프링 세션 동안 7 번의 업데이트 작업을 수행했습니다. 이는 URL에 액세스하는 경우에만 발생합니다. 많은 사용자가 동시에 온라인 상태 인 경우 풀의 연결이 부족할 수 있습니다. 나는 그것이 jdbc와의 스프링 세션의 사실인지 궁금하다. 또는 나는 약간의 설정을 놓쳤다.jdbc와의 스프링 세션이 동시에 업데이트 세션 테이블

이것은 매우 일반적인 시나리오입니다.

스프링 세션 JDBC 지원을 구현하는 동안 가능한 한 효율적으로 기본 데이터베이스와 상호 작용할 수 있도록 많은 노력을 기울였습니다. 그러나 앱을 많은 사용자와 동시에 동시 사용하는 경우 Redis 또는 Hazelcast와 같은보다 우수한 기술을 사용하여 SessionRepository을 다시 고려하는 것이 좋습니다.

'JdbcOperationsSessionRepository'는 명시 적으로'setAttribute (K, V)'만을 인식하는 것으로 보이므로'saved'' updatedCount'가 유효합니다. 'getAttribute (K)'에서 V return으로 맵을 사용하고'setAttribute'없이 맵을 변경했습니다. 그러나 저장소 클래스는이를 유지하지 않습니다. 이것은 정상적인'HttpSession' (세션을 가져올 때 다음 번에 업데이트 할 수있는)의 동작과 충돌합니다. – Tiina

Spring Session'SessionRepository' 구현은 세션을 외부 데이터 저장소에 저장하기 때문에 repo에서 반환 된 세션 인스턴스는 실제로 변경 될 때 저장해야하는 사본입니다. 서블릿 컨테이너의 기본 세션 관리자는 일반적으로 Tomcat과 같은 메모리에 있으며, 이는 동일한 세션 객체를 항상 다루므로 설명 된 접근 방식을 벗어날 수 있습니다. 이것은 HttpSession과 충돌하지 않습니다. AFAIK는 API의 어디에도 문서화되어 있지 않기 때문입니다. Tomcat의 지속적인 세션 관리자를 사용하면 같은 상황이 발생합니다. –

'JdbcOperationSessionRepository'의'updatedCount'는 실제로 "업데이트 된"값을 업데이트 된 것으로 취급해야합니다. 이제는 필수 조건으로이를 분명히 실행합니다. – Tiina
