hibernate - java.sql.SQLException : Invalid value for getInt() - 'foo'

Question

我遇到此错误“getInt() - 'sirocodir' 的值无效”，我在许多论坛中进行了搜索，但没有对我的案例做出回应。

在我的数据库中，“Auteur_Id”类型是 varchar(20)。

我的工厂实体:

@Entity
@Table(name = "Factures")
public class Factures implements java.io.Serializable {

private Collaborateurs collaborateurs;

@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "Auteur_Id", nullable = false)
public Collaborateurs getCollaborateurs() {
    return this.collaborateurs;
}

public void setCollaborateurs(Collaborateurs collaborateurs) {
    this.collaborateurs = collaborateurs;
}

我的合作者实体:

@OneToMany(fetch = FetchType.LAZY, mappedBy = "collaborateurs")
public Set<Factures> getfactures() {
    return this.factures;
}

public void setfactures(Set<Factures> factures) {
    this.factures = factures;
}

我的服务:

@Transactional(readOnly=true)
public List<Factures> AllFacturesContratsClient() {

    return sessionFactory.getCurrentSession()
            .createQuery("from Factures").list();
}

Collaborateurs 类中是否有任何枚举类型？如果有，请确保使用 @Enumerated(EnumType.STRING)
