json은 MONGODB 및 Hibernate-OGM을 사용하여 유형을 직렬화 할 수 없습니다.

Hibernate NamedQuery 및 MongoDB를 사용하여 매우 간단한 쿼리를 실행하려고합니다. 그러나 ENUM 필드를 WHERE 조건에 추가하려고 할 때 아래 예외가 throw됩니다. 조건이 예상대로 작동 WHERE에 열거하지 않고json은 MONGODB 및 Hibernate-OGM을 사용하여 유형을 직렬화 할 수 없습니다.

는 개체와 함께 사용 ENUM의 예있다. 코드에서 enum 클래스는 엔터티의 내부 클래스입니다.

@Entity 
@Indexed(index="social_connection") 
@NamedQueries({ 
    @NamedQuery(name = "social.getConnectionUserById", query = "select s from SocialConnection s where s.provider = :provider and s.providerUserId = :providerUserId")}) 

@Table(name = "social_connection") 
@JsonAutoDetect(fieldVisibility = JsonAutoDetect.Visibility.NONE, getterVisibility = JsonAutoDetect.Visibility.NONE, isGetterVisibility = JsonAutoDetect.Visibility.NONE, setterVisibility = JsonAutoDetect.Visibility.NONE) 
public class SocialConnection extends DateEntity { 

public static enum SocialProvider { 

    TWITTER("Twitter"), 
    FACEBOOK("Facebook"), 
    LINKEDIN("LinkedIn"); 

    private String name; 

    SocialProvider(String name) { 
     this.name = name; 
    } 

    public String getName() { 
     return name; 
    } 
} 

private static final transient Logger LOG = LoggerFactory.getLogger(SocialConnection.class); 

private SocialProvider provider; 

private String providerUserId; 


public SocialConnection() { 
} 


@Enumerated(EnumType.STRING) 
@NotNull 
public SocialProvider getProvider() { 
    return provider; 
} 

public void setProvider(SocialProvider provider) { 
    this.provider = provider; 
} 

@NotNull 
public String getProviderUserId() { 
    return providerUserId; 
} 

public void setProviderUserId(String providerUserId) { 
    this.providerUserId = providerUserId; 
}

필자는 테스트하지 않았지만 해결하기 전에이 버그의 해결 방법이 될 수 있습니다.

json은 MONGODB 및 Hibernate-OGM을 사용하여 유형을 직렬화 할 수 없습니다.
