hibernate/Spring/Jpa @oneToMany 캐스케이드 업데이트

Question

데코레이터에 캐스케이드 = CascadeType.ALL을 추가하려고합니다. 스프링에서 내 버전 modele을 여러 필드에 하나씩 추가하려고합니다. 모든 하이퍼 매개 변수를 업데이트 할 때마다 업데이트합니다. 아래에서 볼 수 있습니다. 내가 JSON을 업데이트하고 2에서 필드가 parameterValue의 값을 변경 .I 그것과 풋을 시도

하지만 나는 500 회의 내부 서버 오류가 발생하고 null 제약 조건 위반과 관련된 하나의 추적 추적을 수행합니다.

이 오류가 발생하여 버전을 업데이트 할 때 어떻게 내 hyperParameters를 업데이트 할 수 있습니까?

Answer 1

사용 @PreUpdate 등 같은 HyperParameter 클래스의 @PrePersist 콜백 :

@PreUpdate 
@PrePersist 
public void setChildObjects() { 
    if (getVersions() != null) 
    { 
     for (Version version : getVersions()) 
     { 
      version.setHyperParameters (this); 
     } 
    } 
}

Answer 2

당신은 유효성 검사 오류가 있습니다. null 값을 사용하여 interpolatedMessage를 넣으려고합니다. Ok. 그러나이 필드에서 @NotNull 어노테이션을 먼저 제거하십시오.

Answer 3

두 솔루션 모두 실제로 해당 항목에서 설명한 내용 때문에 두 번째 오류가 발생했습니다 : Spring data rest one to many cascade all. 난 단지 @JsonManagedReference와 @JsonBackReference를 추가해야했는데 왜냐하면 나는 계단식으로 내 HyperParameters를 업데이트하려고 할 때 버전의 참조에서 마샬링 문제를 가졌기 때문이다.
