jpa-only bundle을 시작하면 내 질문에 "Cycle detected while trying to load class" 오류가 발생합니다.ClassNotFoundException : 클래스를로드하는 중 사이클이 감지되었습니다. - Karaf에서 JPA 번들을 시작할 때
I 받는다는 아키와 JPA 번들을 생성하고, 그것의 pom.xml는 물론 persistence.xml 첨가 이클립스 툴을 이용하여 생성 Karaf (4.0.1), Aries Blueprint, MySQL, OpenJPA, OpenJDK 1.8. 엔티티 클래스와 함께 사용하도록 수정 하였다.
나는 그것을 컴파일하고 오류없이 Karaf에 설치할 수 있습니다. 번들을 시작할 때 오류가 발생했습니다. 이 클래스는 잘 실행됩니다. Karaf 2.x (Geronimo App Server).
조인이없는 클래스를 하나만 생성하면 번들이 완벽하게 시작되므로 클래스의 @OneToMany/@ManyToOne 주석 필드와 관련 될 수 있습니다. 나는 pax-jdbc-mysql 방법을 시도했지만 (청사진을 사용하지 않음) dataSource 외의 동일한 결과가 성공적으로 생성되었습니다. 수업에는 jpa 개의 특수 효과가 있습니다.
