Hibernate-mapping-Ausnahme: nicht bekommen Konnte Konstruktor für org.hibernate.Entität.SingleTableEntityPersister

Post Hibernate buildSessionFactory() Ausnahme und Nicht bekommen konnte Konstruktor für org.hibernate.persister.Entität.SingleTableEntityPersister beschreibt die situation ähnlich, allerdings habe ich noch nicht lösen können, warum folgender code generiert org.hibernate.MappingException: nicht bekommen Konnte Konstruktor für org.hibernate.persister.Entität.SingleTableEntityPersister Fehler. Erstelle ich ein login, mit JSP, Servlets und Hibernate. Bitte helfen Sie mir, resol

Mein POJO-Klasse für die Benutzer ist:

@Entity
@Table(name = "Users")
public class User implements Serializable {

    private static final long serialVersionUID = 1986328586398921108L;

    @Id
    @GeneratedValue
    @Column(name="ID")
    private Long id;

    @NotNull
    @Column(name="NAME", unique = true)
    private String name;


    @NotNull
    @Column(name="PASSWORD")
    private String password;

    public User() {}

    public Long getId() {
        return id;
    }
    public void setId(Long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }

    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
}

Entsprechenden MySQL-Datenbank-Tabelle:

create table Users (
    ID bigint not null auto_increment primary key,
    NAME varchar(20) not null unique,
    PASSWORD varchar(20) not null
);

hibernate.cfg.xml (befindet sich im src-Ordner)

        <!-- Name the annotated User class -->
        <mapping class = "pojo.User"/>

    </session-factory>
</hibernate-configuration>

Bitte auch kommentieren, ist es vorteilhaft, zu serialisieren der Klasse. Vielen Dank im Voraus!

Edit 1:
Klasse, ich bin SessionFactory initialisieren innerhalb:

public class HibernateUtil {

    private static final SessionFactory sessionFactory;
    static {
        try {
            Configuration configuration = new Configuration();
            configuration.configure();
            ServiceRegistry serviceRegistry = new ServiceRegistryBuilder()
                                                .applySettings(configuration.getProperties())
                                                .buildServiceRegistry();
            sessionFactory = configuration.buildSessionFactory(serviceRegistry);
        } catch (Throwable e) {
            System.err.println("Initializing session factory failed: " + e);
            throw new ExceptionInInitializerError(e);
        }
    }

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }
}

Fügen Sie Ihre class wo Sie initialisieren SessionFactory.

Ich das gleiche problem hatte, folgte die Antwort von Vitalii Supryhan und ich fügte hinzu:
```
<dependency>
    <groupId>javassist</groupId>
    <artifactId>javassist</artifactId>
    <version>3.12.1.GA</version>
</dependency>
```
In der pom.xml - Datei, aktualisiert die maven-Projekt (anklicken mit der rechten Taste auf die project->maven->update project)

Und das problem war gelöst!! Danke!

Hatte solche problem. Die Lösung wurde für die Beurteilung der Abhängigkeit:
javassist-x.xx.x-y.jar
aus der hibernate-distribution
