스프링 4와 JPA2 : 재 연결 지연

Question

죄송합니다.

스프링 4를 처음 사용하면서, 나는 그것이 정말로 도움이되는지 또는 방해가되는지를 의심하기 시작했습니다. 세션이 만료되면 36 초에서 60 초 사이에 다시 연결됩니다.

사용 : Hibernate4 + JPA2 + HikariCP (수영장) + Hibernate.spatial

봄 부팅 나는 병목 현상이 줄에 별표 (*)를 넣어.

Answer 1

분명히 여기에 공유되지 않은 코드에 문제가있는 것 같습니다. 이 기사에서 답을 찾았습니다. http://zeroturnaround.com/rebellabs/how-to-use-jpa-correctly-to-avoid-complaints-of-a-slow-application/

JSON 응답으로 보내진 마지막 객체가 많은 것입니다. 단순히 게으른 모든 것을 제거하면 효과가있는 것처럼 보입니다.

코드를 다시 구성 해 보겠습니다. 뭐든지 여기로 돌아와.

편집

문제는 다른이었다. AWS의 서버 응용 프로그램과 Azure의 데이터베이스가 있었지만 JPA에서는 느린 데이터베이스와 다시 연결했지만 JPA에서는 표시하지 않았습니다.

모든 AWS에 남았고 "볼을 보았다"(물론 브라질인이 말한 것처럼 7 배 1 배는 그리 많지 않습니다 ... 롤).

Answer 2

최소한, 그것은 당신이 HikariCP의 구버전을 사용하고있는 것처럼 보입니다. 참조 된 여러 속성은 더 이상 지원되지 않습니다. HikariCP를 1.4.0으로 업그레이드하는 것이 좋습니다. HikariCP 설정을 다음 권장 설정으로 변경하십시오.

hibernate.connection.provider_class=com.zaxxer.hikari.hibernate.HikariConnectionProvider 
hibernate.hikari.minimumIdle=10 
hibernate.hikari.maximumPoolSize=30 
hibernate.hikari.idleTimeout=300000 
hibernate.hikari.maxLifetime=600000
