双向hibernate - org.hibernate.AnnotationException：未知的mappedBy in：error-Java 学习之路

我有4个表kode_pos，korwil，用户和wafat . 在Korwil类中，它保存来自用户的外键并将主键提供给kode_pos，这意味着在korwil类@OneToOne和@OneToMany中有2个映射，

我收到了这个错误

org.hibernate.AnnotationException：未知的mappedBy在：org.ppbni.splatter.model.UserAdmin.korwil，引用未知属性：org.ppbni.splatter.model.Korwil.useradmin`当我运行应用程序〜

这是错误的，

enter image description here

这是我的kode_pos类

package org.ppbni.splatter.model;

import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.FetchType;
import javax.persistence.JoinColumn;
import javax.persistence.GeneratedValue;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name="kode_korwil")
    private Korwil korwil;

    /**Setter and Getter Methods**/

这是我的korwil课，

    @OneToOne
    @MapsId
    @JoinColumn(name="no_dana")
    private UserAdmin useradmin;

    /**Setter and Getter Methods**/
}

这是我的控制员，

@SuppressWarnings("deprecation")

    SessionFactory factory = new Configuration().configure().buildSessionFactory();
    Session session = factory.openSession();

    String nama = request.getParameter("nama");
    String kota = request.getParameter("kota");

    System.out.println(nama);
    System.out.println(kota);

    Query query = session.createQuery("from UserAdmin where (nama_depan = :namadepan or nama_tengah = :namatengah or nama_belakang = :namabelakang) or kota = :kota");
    query.setParameter("namadepan", nama);
    query.setParameter("namatengah", nama);
    query.setParameter("namabelakang", nama);
    query.setParameter("kota", kota);
    System.out.println(query);

    @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);

}

这是错误，

Hibernate通过持久化类生成数据库模式时发生异常 .

我已经用Hibernate 5检查了你的映射 - 没有任何这样的异常（我当然不确定代码的其他部分） .

我不知道你的Hibernate版本，看起来像Hibernate 4.但无论如何，这部分代码异常上升

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 )
        );
    }

抛出 throw new MappingException( "Unable to find entity: " + value.getReferencedEntityName() ) 并 grab 它是一个非常奇怪的逻辑 . 并且错误消息非常混乱 .

otherSide 是你的 Korwil 而 otherSideProperty 是你的 Korwil.useradmin . Hibernate不认为 Korwil 是一个实体 . 可能的原因：您没有将其添加到映射中，或者扫描实体的包时遇到一些问题 . 你需要弄清楚为什么Hibernate认为 UserAdmin 是一个实体而 Korwil 不是 .
