✔ Hibernate: MappingException und generelles

Tobias Köhler · 31. März 2008

Ich versuche jetzt seit einigen Tagen den Einstieg in Hibernate zu bekommen. Leider ist es mir bis jetzt noch nicht gelungen, eine Tabelle anzulegen. Ich bekomme immer eine MappingException, die besagt dass das Objekt eine unbekannte Entität ist. Ich kann machen was ich möchte, sie geht nicht weg.

Meine hibernate configuration:

Code:

<!DOCTYPE hibernate-configuration PUBLIC
	"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
	"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
	<session-factory>
 		<!-- Datenbank Connection Einstellungen -->
		<property name="connection.driver_class">
			oracle.jdbc.driver.OracleDriver</property>
		<property name="connection.url">...</property>
		<property name="connection.username">...</property>
		<property name="connection.password">...</property>
		
		<property name="hibernate.dialect">
			org.hibernate.dialect.Oracle9Dialect</property>
			
		<!-- Zusätzliche Hibernate-Properties -->
		<property name="hibernate.show_sql">true</property>
		<property name="hibernate.format_sql">true</property>
		
		<!-- Auflistung der gemappten Klassen -->
		<mapping class="test.entities.Production"/>
		<mapping class="test.entities.Format"/>
		
	</session-factory>
</hibernate-configuration>

Dazu die Klasse Format:

Java:

@Entity
@Table(name = "ERP_TEST_DG_FORMAT")
public class Format 
{
	private int id;
	private int x;
	private int y;
	
	public Format()
	{}

	@Id
	@GeneratedValue(strategy = GenerationType.IDENTITY)
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	@Column(name = "x_width")
	@Basic(optional = false)
	public int getX() {
		return x;
	}
	public void setX(int x) {
		this.x = x;
	}
	@Column(name = "y_height")
	@Basic(optional = false)
	public int getY() {
		return y;
	}
	public void setY(int y) {
		this.y = y;
	}
}

und dann noch meine Testklasse:

Java:

public class Test 
{	
	public static void main(String[] args)
	{
		AnnotationConfiguration configuration = new AnnotationConfiguration();
		configuration.configure();
		
		SessionFactory sf = configuration.buildSessionFactory();
		Session s = sf.openSession();
		Transaction t = s.beginTransaction();
		
		try
		{			
			Format format = new Format();			
			format.setX(25);
			format.setY(25);
						
			s.save(format);
			
			t.commit();
		}
		catch(Exception e)
		{
			System.out.println(e);
			t.rollback();
		}
		finally
		{
                       s.close();
                       sf.close();
		}
	}
}

Hoffentlich könnt ihr mir helfen

Hallo,

langsam müsstest du aber wissen, dass man die Exception auch mitpostet.

^^glatt vergessen
Aber ehrlich gesagt auch unwichtig, denn sie sieht so aus:

org.hibernate.MappingException: Unknown entity: test.entities.Format

Also genau das, was ich bereits gesagt hatte

Oliver Gierke · 31. März 2008

Schalt mal bitte das Loglevel auf DEBUG und poste die Ausgabe. Hast dich immer noch nicht durchringen können, auf JPA zu setzen?

Oder ist plain Hibernate explizite Anforderung?

Ich würde auch vorschlagen die JPA zu nutzen.

Es soll Hibernate sein

Und wie schalte ich den Logger auf Debug? Mit Log4J hab ich zwar schonmal gearbeitet, aber muss ich die xml datei in der hibernate config datei mit angeben oder wie genau läuft das ab?

Tobias Köhler · 31. März 2008

Ok, schon gut, habs jetzt hinbekommen mit dem Logging. Das Problem ist aber, dass es bei der Genauigkeit der Exception bleibt

Oliver Gierke · 31. März 2008

Tobias Köhler hat gesagt.:
Es soll Hibernate sein

Diese Entscheidung würde ich an deiner Stelle auf Sinnhaftigkeit hinterfragen. Hibernate ist problemlos als Persistenzprovider hinter JPA möglich. Alles was JPA dann tut, ist die Vereinfachung des Mappings, Sessionhandlings usw. Es wird also für die Standardfälle einfach nur einfacher. Trotzdem hast du die möglichkeit Hibernate spezifische Features zu nutzen. Wie gesagt, ich hab bisher noch keine sinnvolle Begründung für die Verwendung von plain Hibernate gehört.

Tobias Köhler hat gesagt.:
Ok, schon gut, habs jetzt hinbekommen mit dem Logging. Das Problem ist aber, dass es bei der Genauigkeit der Exception bleibt

Sicher, es geht aber auch nicht um die Exception, sonder darum, welche Files schon geparst wurden, was Hibernate wie wo schon angestellt hat - sprich - an welcher Stelle im Bootstrapprozess die Exception fliegt. Daher wäre so ein Logdump äußerst hilfreich, die Fehlermeldung einzuordnen.

Ok, danke schonmal

Ich werde also einfach 2 Versionen anfertigen, auf Verdacht hin schonmal mit JPA
Hier die Ausgabe des Loggers

Das hätte ich vielleicht mal früher sehen müssen.

Code:

catch(Exception e)
{
            System.out.println(e);
            t.rollback();
}

Ändere das mal in

Code:

catch(Exception e)
{
            e.printStackTrace();
            t.rollback();
}

Dann wird die Exception auch etwas ausführlicher.
