KellyM :
데이터 JPA, 메일, 보안, 웹, thymeleaf : 나는 다음과 같은 "선발"꽤 전형적인 봄 부팅 기반의 웹 응용 프로그램, 봄 부트 버전 2.2.4이 있습니다. 내 데이터 소스와 봄 세션 JDBC로 PostgreSQL을 사용하고 있습니다. 응용 프로그램은 데이터베이스 연결과 관련된 오류를 몇 시간 동안 벌금을 실행하지만, 결국 발생합니다 :

이 응용 프로그램은 내가 문제가 발생하지 전에 내가 만든 많은 구조가 유사하다. 응용 프로그램은 몇 시간 동안 생산되어 왔으며 문제가 발생하지 않았다. 이는 한 달 전에 어쩌면 시작했지만, 점점 더 자주되고있다. 응용 프로그램은 정기적으로 업데이트되지만 데이터베이스 논리에는 업데이트는 꽤 오랫동안 수행되지 않았습니다. 또 다른 응용 프로그램의 연락처와 동일한 DB 및이 문제가 발생하지 않았다. 데이터베이스에 로그는 오류를 공개하지 않습니다.
모든 포인터는 크게 감상 할 수있다. 솔직히, 나는 손실에 조금입니다. I 세트 logging.level.com.zaxxer.hikari=DEBUG및 logging.level.org.hibernate=INFO그것은 나를 문제를 추적 도움이 될 수 있다는 희망에서 (이 문제와 무관 디버그 생산 너무 많은 출력),하지만 성공. 이러한 수준의 전체 스택 위에 표시됩니다.
크리스 풍미 :
어떤 일이 일어나고하면 응용 프로그램이 풀에서 DB 연결을 얻으려고 노력하고 더 이상 연결 (그들은 모두 사용되지 않는) 사용할 수 없기 때문에 30 초 (기본값) 후 시간 초과입니다.
당신은 히카리에 대한 이러한 값을 설정하거나 기본값을 그대로 있습니까?
datasource:
hikari:
connection-init-sql: SELECT 1
connection-test-query: SELECT 1
auto-commit: true

leak-detection-threshold: 45000

문제를 찾으려면 당신이 두 가지를 제안한다 :
- 누출 감지 켜기 :
leak-detection-threshold: 45000그것은이 같은 로그 문을 인쇄합니다 :

그것은 당신에게 어디에 응용 프로그램, 이상 45 초 동안 연결에 들고되는 프로세스이다. 당신이 원하는 경우 30 변경할 수 있습니다.
- 로거에서이 DEBUG 가능 :
logging:

com.zaxxer.hikari.pool.HikariPool: DEBUG
너무 자주이 모든 같은 문장을 기록 할 :
2020-02-07 04:17:38,798 DEBUG HikariPool-1 housekeeper HikariPool.logPoolState - HikariPool-1 - Pool stats (total=10, active=1, idle=9, waiting=0)
활성이 전체에 동일 할 때 당신은 당신의 풀이 가득 사용하고 알고 당신은 대기 번호 상승을보고 시작합니다. 기본적으로, 그 시점에서 당신은 연결을 포기하거나 응용 프로그램을 다시 시작 연결을 새고 어떤 과정이 필요합니다. 그렇지 않으면, 당신은 그 오류를보고 시작합니다.
또한 참고로 30 초 (기본값) 시간 제한에 대한 연결을 기다리는 긴 것입니다. 이 웹 페이지에서 오는 요청이있는 경우, 어떤 일이 30 초 동안 실제 사용자 대기 (대부분의 사람들이 그렇게 오래 기다릴 너무 참을성이)가 기억한다. 당신이 우리의 응용 프로그램에서 볼 수 있듯이 우리는 3000ms 설정 (3 초).
