AttributeConverter # convertToEntityAttribute 내가 나의 실체에 대해 다음 컨버터를 작성했습니다 java.lang.ClassCastException가

를 던졌습니다 :AttributeConverter # convertToEntityAttribute 내가 나의 실체에 대해 다음 컨버터를 작성했습니다 java.lang.ClassCastException가

@Converter(autoApply = true) 
public class UUIDConverter implements AttributeConverter<UUID, String> { 

    @Override 
    public String convertToDatabaseColumn(UUID attribute) { 
     return attribute.toString(); 
    } 

    @Override 
    public UUID convertToEntityAttribute(String dbData) { 
     return UUID.fromString(dbData); 
    } 

}

내가 지금 기본 키로 UUID를 사용하고 싶습니다. 컨버터는 적용하지만 나에게 매우 이상한 보이는 다음과 같은 오류가 발생됩니다 : 그것은 JPA처럼 보이는

Caused by: javax.persistence.PersistenceException: An exception occurred while calling convertToEntityAttribute on converter class UUIDConverter with value fe00aab3-858c-4478-9b19-1defe5c070ba 
Caused by: java.lang.ClassCastException: java.util.UUID cannot be cast to java.lang.String"}}

는 MySQL 데이터베이스에서 UUID를 검색하고 convertToEntityAttribute 메소드를 호출하는 문제가있다. 그게 전부 이상해. 누구 아이디어?

BTW : 컬럼이 varchar 형 (255) 및 JPA 제공자되는 데이터베이스에서 제이보스 8에

@BalusC 속성 변환기가 반드시 호출됩니다. – perotom

다음 번에 키워드를 넣는 대신 제목에 문제를 설명하십시오. 키워드에 태그 섹션을 사용하십시오. – BalusC

@ BalusC 감사하지만 convertToEntityAttribute도 확실히 호출됩니다. 오류 메시지를보십시오. – perotom

는 UUID 특성 주석 있는지 확인 @ 변환기

@Basic 
    @Converter (
