UPDATE 3 : 나는 문제를 발견했다! 'Checks'는 persistentcollection이지 배열 콜렉션이 아닙니다. persistentcollection이 JMS serializer에서 제대로 작동하지 않습니다. 그룹 개체의 덤프를 인쇄 할 때 dev_log (= correct)에서 2 개의 쿼리를 볼 수 있습니다. serializer를 사용하여 객체를 구문 분석 할 때 +10 개의 쿼리 (= 좋지 않음)가 표시됩니다.

해결책을 찾고 난 후 lazyloading을 사용하지 못하도록 시도했지만 문제가 해결되지 않았습니다.

하면 해당 페이지 하나 하나에 모범을 따르려고 노력 적이있다? joincolumns 제거, 그냥 조인 테이블을 추가하고 이름을 지정하십시오. 또한 생성자를 가져야합니다. – Koalabaerchen

같은 문제가 있습니다. 어떻게 컬럼 이름을 기본값 : "entity_id"와 다른 것으로 설정할 수 있습니까? 이 테스트를 위해 컬럼 이름을 바꿀 수 있습니다. – jsprds
