org.hibernate.id.IdentifierGenerationException：這個類的ids必須在調用save（）之前手動賦值save（）

雖然我手動設置了ID，但我沒有在這裏使用自動生成的鍵，但我得到了上述錯誤。當我設置鍵和對象傳遞給org.hibernate.id.IdentifierGenerationException：這個類的ids必須在調用save（）之前手動賦值save（）

entityManager.persist(obj);

它給出了上述錯誤。任何幫助...... PLZ

感謝

這是InstallationInfo類，並堅持在installationInfo對象時，我得到了上述錯誤。完整的錯誤是

org.hibernate.id.IdentifierGenerationException: ids for this class must be manually assigned before calling save(): se.cambio.cimonitor.jpa.table.ModuleInfo

你能發佈你的實體類嗎？我認爲問題在實體映射 –

它在ModuleInfo中給出了一個錯誤，當持久化InstallationInfo時，我不知道任何想法，並且我確定在設置它之前設置了installationId。 –

它不是抱怨InstallationInfo，而是關於ModuleInfo。由於您在InstallationInfo內部保留了新的ModuleInfo實例，因此這些ModuleInfo也必須分配其ID。 –

你有一個梯級上的所有ModuleInfos集合，因此當您保存InstallationInfo時，它將嘗試保存所有關聯的ModuleInfos。您需要確保在保存InstallationInfo對象之前設置了ModuleInfos的ID。

@OneToMany(fetch = FetchType.EAGER, mappedBy = "installationInfo", 
    targetEntity=ModuleInfo.class, cascade={CascadeType.ALL}) //targerEntity is added by Isuru 
public Set<ModuleInfo> getModuleInfos() { 
    return this.moduleInfos; 
}
