Problem mit einer Wertklasse (component)

Hiperman · **Joined:** Mon Jul 31, 2006 4:59 pm **Posts:** 53

Benutze Hibernate 3.2 und ich versuche meine Klasse "Termin" zusammen mit meiner Klasse "Zeitpunkt" zu speichern. "Zeitpunkt" soll eine Wertklasse sein. Ein Zeitpunkt wird nur als Teil des Geschäftsobjekts "Termin" gespeichert. Leider funktioniert das noch nicht so wie ich will... :(

Habe folgende Tabelle in der MySql5-Datenbank:

Code:

CREATE TABLE `termin` (
`id` BIGINT NOT NULL AUTO_INCREMENT PRIMARY KEY ,
`titel` VARCHAR( 200 ) NOT NULL ,
`beschreibung` VARCHAR( 200 ) NOT NULL ,
`zeit` TIMESTAMP NOT NULL ,
`ort` VARCHAR( 200 ) NOT NULL 
) TYPE = innodb;

Die Klasse "Zeitpunkt"

Code:

package uebung1Package;

public class Zeitpunkt {
   private int _minute;
   private int _stunde;
   private int _tag;
   private int _monat;
   private int _jahr;
   
   public int get_jahr() {
      return _jahr;
   }
   public void set_jahr(int _jahr) {
      this._jahr = _jahr;
   }
   public int get_minute() {
      return _minute;
   }
   public void set_minute(int _minute) {
      this._minute = _minute;
   }
   public int get_monat() {
      return _monat;
   }
   public void set_monat(int _monat) {
      this._monat = _monat;
   }
   public int get_stunde() {
      return _stunde;
   }
   public void set_stunde(int _stunde) {
      this._stunde = _stunde;
   }
   public int get_tag() {
      return _tag;
   }
   public void set_tag(int _tag) {
      this._tag = _tag;
   }
   

}

Die Klasse "Termin"

Code:

package uebung1Package;


public class Termin
{
  private long _id;
  private String _titel;
  private String _beschreibung;
  private String _ort;
  private Zeitpunkt _zeit;
  
  
  public void setZeit (Zeitpunkt z)
  {
     _zeit = z;
  }
  
  public Zeitpunkt getZeit()
  {
     return _zeit;
  }
  
  public String getTitel ()
  {
    return _titel;
  }

  public void setTitel (String titel)
  {
    _titel = titel;
  }

  
  public String getBeschreibung ()
  {
    return _beschreibung;
  }

  public void setBeschreibung (String beschreibung)
  {
    _beschreibung = beschreibung;
  }

  public String getOrt ()
  {
    return _ort;
  }

  public void setOrt (String ort)
  {
    _ort = ort;
  }

  public long getId ()
  {
    return _id;
  }

  public void setId (long id)
  {
    _id = id;
  }
}

Mapping "Termin.hbm.xml"

Code:

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC 
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>

   <class name="uebung1Package.Termin">
      <component name="zeit">
         <property name="minute"/>
         <property name="stunde"/>
         <property name="tag"/>
         <property name="monat"/>
         <property name="jahr"/>
      </component>
      
   
   
      <id name="id" type="long">
         <generator class="assigned">
         </generator>
      </id>
      
      <property name="titel" />
      <property name="beschreibung" />
      <property name="zeitpunkt" column="zeit" type="timestamp"/>
      <property name="ort" type="string"/>
      
      
      
   </class>
   </hibernate-mapping>

Die "Hibernate.cfg.xml" (müsste eigentlich stimmen)

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>
      <mapping resource="uebung1Package/Termin.hbm.xml"/>
   </session-factory>
</hibernate-configuration>

So das waren nun die wichtigsten Dateien. Die Fehlermeldung lautet:

Kann mir jemand helfen dieses Problem zu lösen? Vielen dank im voraus!

hallo hiperman,

auch hier wie bei deinem anderen posting auch : erst "id" und dann "component". Hibernate ist was die Reihenfolge der Elemente in den XML-files betrifft sehr pingelich.

grüße
