Spring和Hibernate：自動連接依賴項注入失敗

Question

我正在使用Spring和Hibernate在JAVAEE Project中工作，當我嘗試生成數據庫時，由於這個問題，我無法執行以下操作：

這是Seance的映射：

<class name="ma.emsi.gestion.model.Seance" table="SEANCE">

    <id name="idSeance" type="int">
        <column name="ID_SEANCE" />
        <generator class="increment" />
    </id>


    <property name="dateDebut" type="date">
        <column name="DATEDEBUT" />
    </property>

    <property name="dateFin" type="date">
        <column name="DATEFIN" />
    </property>

    <property name="heureDebut" type="date">
        <column name="HeureDebut" />
    </property>
    <property name="heureFin" type="date">
        <column name="HEUREFIN" />
    </property>
    <property name="salle" type="string" length="5">
        <column name="SALLE" />
    </property>

    <many-to-one name="planing" class="ma.emsi.gestion.model.Planing">

        <column name="ID_PLANING" />
    </many-to-one>

    <many-to-one name="affectation" class="ma.emsi.gestion.model.Affectation">

        <column name="ID_AFFECTATION" />
    </many-to-one>
</class>

這是Affectation的映射：

<class name="ma.emsi.gestion.model.Affectation" table="AFFECTATION">
        <id name="idAffectation" type="int" column="ID_AFFECTATION">
            <generator class="increment"/>
        </id>

        <many-to-one name="matiere" class="ma.emsi.gestion.model.Matiere">
            <column name="ID_MATIERE" />
        </many-to-one>
        <many-to-one name="prof" class="ma.emsi.gestion.model.Prof">
            <column name="ID_PROF" />
        </many-to-one>

        <bag name="seances" cascade="all">
            <key column="ID_AFFECTATION" />
            <one-to-many class="ma.emsi.gestion.model.Seance" />
        </bag>


        <many-to-one name="classe" class="ma.emsi.gestion.model.Classe">
            <column name="ID_CLASSE" />
        </many-to-one>

    </class>

這是我的Seance和Affectation模型班：

public class Classe {

private String filiere;
private int groupe;
private int idClasse;
private int niveau;

private Collection<Module> modules;
private Collection<Planing> plannings;




public Classe() {
    super();
    // TODO Auto-generated constructor stub
}
public String getFiliere() {
    return filiere;
}
public void setFiliere(String filiere) {
    this.filiere = filiere;
}
public int getGroupe() {
    return groupe;
}
public void setGroupe(int groupe) {
    this.groupe = groupe;
}
public int getIdClasse() {
    return idClasse;
}
public void setIdClasse(int idClasse) {
    this.idClasse = idClasse;
}
public int getNiveau() {
    return niveau;
}
public void setNiveau(int niveau) {
    this.niveau = niveau;
}
public Collection<Module> getModules() {
    return modules;
}
public void setModules(Collection<Module> modules) {
    this.modules = modules;
}
public Collection<Planing> getPlannings() {
    return plannings;
}
public void setPlannings(Collection<Planing> planning) {
    this.plannings = planning;
}


/*****************************************/
public class Affectation {

    private int idAffectation;
    private Classe classe;
    private Matiere matiere;
    private Support support;
    private Prof prof;

    private Collection<Seance> seances;

    public Affectation() {
        super();

    }


    public int getIdAffectation() {
        return idAffectation;
    }

    public void setIdAffectation(int idAffectation) {
        this.idAffectation = idAffectation;
    }

    public Classe getClasse() {
        return classe;
    }

    public void setClasse(Classe classe) {
        this.classe = classe;
    }

    public Matiere getMatiere() {
        return matiere;
    }

    public void setMatiere(Matiere matiere) {
        this.matiere = matiere;
    }

    public Support getSupport() {
        return support;
    }

    public void setSupport(Support support) {
        this.support = support;
    }

    public Prof getProf() {
        return prof;
    }

    public void setProf(Prof prof) {
        this.prof = prof;
    }


    public Collection<Seance> getSeances() {
        return seances;
    }


    public void setSeances(Collection<Seance> seances) {
        this.seances = seances;
    }

}

最后是我的DAO實現：

@Repository("daoAffectation")
public class DaoAffectationImpl implements IdaoAffectation {

    @Autowired
    SessionFactory sessionFactory;

    @Override
    public void add(Affectation afectation) {

        sessionFactory.getCurrentSession().save(afectation);

    }

    @Override
    public void update(Affectation affectation) {
        // TODO Auto-generated method stub
        sessionFactory.getCurrentSession().update(affectation);
    }

    @Override
    public void delete(Affectation affectaion) {
        // TODO Auto-generated method stub
        sessionFactory.getCurrentSession().delete(affectaion);
    }

    @Override
    public Affectation getById(int idAffectation) {
        // TODO Auto-generated method stub
        return (Affectation)sessionFactory.getCurrentSession().load(Affectation.class, idAffectation);
    }

    @Override
    public List<Affectation> getAll() {

        return sessionFactory.getCurrentSession().createCriteria(Affectation.class).list();
    }

}

有人可以幫我嗎

Seance類模型：

Answer 1

在您的stacktrace中，您Could not parse mapping document from resource ma/emsi/gestion/mapping/Seance.hbm.xml看起來好像找到了xml，但是它不包含預期的結構。
