매 초마다 REST 서비스가 작동합니다.

jax-rs REST 서비스에 문제가 있습니다.매 초마다 REST 서비스가 작동합니다.

서비스가 제대로 작동하지 않습니다. 모든 두 번째 요청 서비스가 나에게 예외를 던져 :

이것은 REST 또는 JAX-WS의 잘못된 태깅과 아무 관련이 없습니다. 이것은 데이터 계층 문제입니다. 연결을 오래 유지하기 위해 MySQL의 타임 아웃 설정에서 작업해야합니다. – kolossus

문제점은 mysql 데이터 소스 구성에 있습니다. 이 두 매개 변수를 데이터 소스 정의에 추가하십시오.

testOnBorrow="true" validationQuery="select 1"

고마워요! 이제 완벽하게 작동합니다. :) –

나는 이것이 서버 측 문제라고 생각합니다. 그것의 클래스가 명확하게 보이는 클래스 BaseDAOgetAll_fetchEager이 방법에서는 어떤 이유로 인해 실패한 몇 가지 기준 쿼리를 만들고 있습니다. 귀하의 기준 쿼리 문제를 해결하면 해결할 것이라고 확신합니다. 연결 속성이 올바르게 설정되어 있는지 확인하고 데이터베이스에 연결할 수 있습니다.

대답은 스택 추적에 있다고 생각합니다.

서버에서 성공적으로받은 마지막 패킷은 22.477.953 밀리 초 전입니다. 서버에 성공적으로 보낸 마지막 패킷은 22.478000 밀리 초 전입니다. 서버 구성 값인 'wait_timeout'보다 깁니다. 응용 프로그램에서 사용하기 전에 연결 유효성을 만료 및/또는 테스트하거나, 클라이언트 시간 초과에 대한 서버 구성 값을 늘리거나 Connector/J 연결 속성 'autoReconnect = true'를 사용하여이 문제를 방지해야합니다.

mysql에 대한 연결이 열려 있지 않으며 자동 다시 연결로 설정되어 있지 않습니다.
