雙向休眠-org.hibernate.AnnotationException：未知的mappingBy in：錯誤

Question

我有4個表kode_pos，korwil，user和wafat。 在Korwil類中，它持有用戶的外鍵並將主鍵提供給kode_pos，這意味着在korwil類@OneToOne和@OneToMany中有2個映射，

我得到這個錯誤

org.hibernate.AnnotationException：未知，映射於：org.ppbni.splatter.model.UserAdmin.korwil，引用的屬性未知：org.ppbni.splatter.model.Korwil.useradmin`，當我運行應用程序時〜

    Query query = session.createQuery("from UserAdmin where (nama_depan = :namadepan or nama_tengah = :namatengah or nama_belakang = :namabelakang) or kota = :kota");

    @SuppressWarnings("unchecked")
    List <UserAdmin> result = query.list();

    for(int i=0; i < result.size(); i++){

        model.addObject("result", result);
    }

    session.close();
    factory.close();

    return userDaftarAnggota(model);

}

Answer 1

Hibernate通過持久類生成數據庫架構時會發生異常。

我已經使用Hibernate 5檢查了您的映射-沒有任何此類異常（當然，我不確定代碼的其他部分）。

我不知道您的Hibernate版本，看起來像Hibernate4。但是無論如何，這部分代碼會出現異常

    PersistentClass otherSide = (PersistentClass) persistentClasses.get( value.getReferencedEntityName() );
    Property otherSideProperty;
    try {
        if ( otherSide == null ) {
            throw new MappingException( "Unable to find entity: " + value.getReferencedEntityName() );
        }
        otherSideProperty = BinderHelper.findPropertyByName( otherSide, mappedBy );
    }
    catch (MappingException e) {
        throw new AnnotationException(
                "Unknown mappedBy in: " + StringHelper.qualify( ownerEntity, ownerProperty )
                        + ", referenced property unknown: "
                        + StringHelper.qualify( value.getReferencedEntityName(), mappedBy )
        );
    }
    if ( otherSideProperty == null ) {
        throw new AnnotationException(
                "Unknown mappedBy in: " + StringHelper.qualify( ownerEntity, ownerProperty )
                        + ", referenced property unknown: "
                        + StringHelper.qualify( value.getReferencedEntityName(), mappedBy )
        );
    }

throw new MappingException( "Unable to find entity: " + value.getReferencedEntityName() )並捕獲它是非常奇怪的邏輯。 錯誤消息非常混亂。

otherSide是您的Korwil ， otherSideProperty是您的Korwil.useradmin 。 Hibernate並不將Korwil視為實體。 可能的原因：您沒有將其添加到映射中，或者沒有掃描實體包的問題。 您需要弄清楚為什么Hibernate認為UserAdmin是一個實體，而Korwil不是。
