웹 응용 프로그램 Extjs, Spring3.0, JPA, Hibernate가 있습니다. 나는 잘 작동하는 단일 엔티티로 검색 페이지를 가지고 있지만 어제 사용자 엔티티에서 @manytoone을 추가하고 애플리케이션이 작동을 멈춘다. Extjs는 예외를 던지기 시작합니다. 디버깅하려고 할 때 @manytoOne 관계의 문제가 발견되었습니다. 아무도 나에게 힌트를 주시겠습니까?Extjs + Spring + JPA + HIbernate

문제 개시 arice 난 BusinessCal 모델 BULookUp objBULookUp 추가 한 경우. BULookUp에 대한 코드와 extjs 파일에 대한 코드를 추가하겠습니다.

내 문제를 조사하려는 노력에 감사드립니다.
변수 strBussUnitId는 BulookUp 모델에 속하는 BusinessCal 모델의 열입니다. BULookUp 모델은 strBussUnitId를 통해 해당 마스터 테이블 데이터를 사용하여 BusinessCal을 저장하고 저장할 수있는 마스터 데이터 테이블입니다.
우리가 extjs를 사용하는 프런트 엔드에서 Noow 나는 strBussUnitId에 해당하는 strBusinessUnitDescription을 구두화할 숫자 인 strBussUnitId를 표시 할 수 없습니다. 이를 위해 Bullookup 모델로 BusinessCal 모델에서 @manytoOne을 만들었습니다.
BusinessCal 모델에 @manytoOne을 추가 할 때 문제가 발생합니다.
