DataNucleus와 JDO를 사용합니다. 영속성 프로세스 동안 "테이블"에 대한 스키마를 생성하기 위해 나는 datanucleus.schema.autoCreateAll=true을 사용하여 DataNucleus에게 스키마 자동 생성을 지시합니다. 테이블에 enty를 만들면 모델 결과에 필드를 추가하려는 시도가 org.neo4j.graphdb.NotFoundException: NODE[68] has no property with propertyKey="newFieldName"이됩니다.Neo4j 데이터베이스에 속성을 추가하는 방법 항목이 포함 된 테이블 (DataNucleus)?
이미 항목이 들어있는 표에 속성을 변경하거나 추가하는 가장 좋은 방법은 무엇입니까?
이것은 스택 추적입니다.
