我正在嘗試保留一個Angebot具有 Attribute 的類，KfzVertrag該類是由 faktor ips 生成的策略類。我正在使用 Spring Boot。
Angebot看起來像這樣：
@Entity
public class Angebot {
@Id
@GeneratedValue
private Long id;
private String angebotName;
private String produktName;
@OneToOne(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
private KfzVertrag vertrag;
public Angebot() {
}
//...Getters and Setters...
KfzVertrag看起來像這樣：
@Entity
@DiscriminatorValue("KV")
@IpsPolicyCmptType(name = "kfz.KfzVertrag")
@IpsAssociations({ "KfzHaftpflichtdeckung", "KfzAssistancedeckung" })
@IpsConfiguredBy(KfzProdukt.class)
@IpsDocumented(bundleName = "org.faktorips.beispiel.model.model-label-and-descriptions", defaultLocale = "de")
public class KfzVertrag extends Vertrag {
//...
/**
* Membervariable fuer die Beziehung KfzHaftpflichtdeckung.
*
* @since 0.0.1
*
* @generated
*/
@OneToOne(mappedBy = "kfzVertrag", cascade = CascadeType.ALL, fetch = FetchType.EAGER, targetEntity = KfzHaftpflichtdeckung.class, orphanRemoval = true)
private KfzHaftpflichtdeckung kfzHaftpflichtdeckung = null;
/**
* Membervariable fuer die Beziehung KfzAssistancedeckung.
*
* @since 0.0.1
*
* @generated
*/
@OneToMany(mappedBy = "kfzVertrag", cascade = CascadeType.ALL, fetch = FetchType.LAZY, targetEntity = KfzAssistancedeckung.class, orphanRemoval = true)
private List<KfzAssistancedeckung> kfzAssistancedeckungen = new ArrayList<>();
/**
* Erzeugt eine neue Instanz von KfzVertrag.
*
* @since 0.0.1
*
* @generated
*/
@IpsGenerated
public KfzVertrag() {
super();
}
//... (The class is very large)
我有一個常規的 Spring 存盤庫擴展JpaRepository<Angebot, Long>。當我想將一個實體保存Angebot到我的 h2 資料庫中時，我總是會收到此錯誤：

由于此處另一個問題中描述的原因，我禁用了spring.devtools.restart類加載器。但我不確定這是否是這個問題的原因。
我已經完成了另一個專案，其中持久性沒有任何問題。但我這個專案與另一個不同的唯一方式是我必須在這個專案中禁用spring.devtools.restart它，并且我在另一個專案上內置了 Linkki UI 版本 1.5.0，在這個專案上我正在嘗試作業Linkki 版本 2.0.0。但我不明白這會如何影響持久性。
有誰知道這里發生了什么？
uj5u.com熱心網友回復：
我認為這不是linkki的問題。似乎 Hibernate 正在嘗試通過序列化來持久化 ProductConfiguration。要序列化 ??ProductConfiguration，您需要在 RuntimeRepository 中配置 IRuntimeRepositoryLookup。但是，這并不重要，因為序列化物件并不是將 Faktor-IPS 與 JPA 一起使用的正確方法。
您需要配置一個AttributeConverter<ProductConfiguration, String>用@Converter(autoApply = true). 可能你的JPA版本和你之前的專案不一樣，所以需要配置不同的？
