One-To-Many Beziehung

Hallo,

habe grade erst mit Hibernate angefangen und wollte mal eine einfache One-To-Many Beziehung versuchen. Leider klappt das nicht. Die Tabellen und Objekt werden angelegt und gespeichert. Leider klappt der Set aufruf nicht, der mir die verschiedenen Objekt geben sollte. (User 1 = n Nachrichten)

User Mapping:

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="example.user.User" table="USERS">
    
       <id name="id" column="USER_ID">
            <generator class="native"/>
        </id>
      <property name="nickname"       column="USER_NICKNAME"       length="50"    not-null="true" />
      <property name="email"          column="USER_EMAIL"       length="100"    not-null="true" />
      <property name="passwort"       column="USER_PASSWORT"       length="50"    not-null="true" />
      <property name="registriert"    column="USER_REGISTRIERT"    type="timestamp" />   
      
      <set name="messages" table="USER_MESSAGES" order-by="MESSAGE_GESCHRIEBEN ASC" inverse="true">
       <key column="MESSAGE_BENUTZER_ID" />
       <one-to-many class="example.messages.Message"/>
      </set>
     
    </class>
   </hibernate-mapping>

User_Message mapping:

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="example.messages.Message" table="USER_MESSAGES">
    
       <id name="id" column="MESSAGE_ID">
            <generator class="native"/>
        </id>
        
      <property name="title" column="MESSAGE_TITLE" length="100" not-null="true" />
      <property name="inhalt" column="MESSAGE_INHALT" length="1000" not-null="true" />
      <property name="geschrieben" column="MESSAGE_GESCHRIEBEN" type="timestamp" />    
          
      <many-to-one name="benutzerId" class="example.user.User" column="MESSAGE_USER_ID" not-null="true"/>
     
    </class>
   </hibernate-mapping>

Hier der Code der User Klasse:

Code:

package example.user;

import java.util.Date;
import java.util.HashSet;
import java.util.Set;

import org.apache.log4j.Logger;

public class User {
   
   private static Logger log = Logger.getLogger(User.class);
   
   private int id;
   private String nickname;
   private String email;
   private String passwort;
   private Date registriert;
   
   private Set messages = new HashSet();
   
   public Set getMessages() {
      log.info("getMessages");
      return messages;
   }

   public void setMessages(Set messages) {
      log.info("setMessages");
      this.messages = messages;
   }

}

Die Objekte werden erfolgreich gespeichert und die Id der Benutzer steht auch bei den Nachrichten. Nur der aufruf der User.getMessages(); liefert kein ergebnis zurück. Es wird einfach ein Set Objekt mit 0 Datensätzen zurück gegeben. Hat einer ne Idee was ich falsch mache.

Habe mich an: http://www.xylax.net/hibernate/onetomany.html orientiert.

Danke im vorraus

ich glaub du hast das mapping von message vergessen (und user zwei mal gepostet).

Ausserdem wäre ein log auf debug level noch hilfreich

Oh ^^

Habs nochmal editiert.

Ich vermute, dass Du in der setUserId Methode von Message, deine bi-direktionale Verknüpfung nicht pflegst.

Hast Du dort einen Aufruf, der was in dieser Richtung macht:

Code:

...
pubic class Message .....

public void setUserId(User user) {
  this.userId = user;
  user.addMessages(this);
}
...

Ausserdem lädst Du deinen User nicht im Client. Versuch mal, nach dem Speichern ein

Code:

User loadedUser = UserBO.loadUser(user.getId());

aufzurufen... dann sollten die Messages eigentlich gleich mitkommen.

Anbei noch ein kleiner Link zur Hibernate Doku:

Yeap.. das mit der User.add funktioniert.

Aber das mit dem User im Client laden ist so nciht richtig. Wenn ich den über Session.save(); speichere, wird das Objekt automatisch aktualisiert und hat alle aktuellen Werte. Also muß man das nicht seperat neu laden.

Danke

Generell mag das funktionieren, aber nur für Objekte, die nicht detached sind. Da Du aber Deine Session nach jeder User / MessageBO funktion schliesst hast Du ein Problem. Laut Deinem Log file wird die Session 3 mal geschlossen. Beim letzten Aufruf ist das User Objekt Detached und wird somit nicht nachgezogen. Prüf das Verhalten mal in nem Debugger.

Ein Object wird niemals automatisch aktualisiert.
Es kann sein, dass die Daten in der DB richtig geschrieben werden, aber Hibernate sucht nicht nach allen Objekten, die im Speicher sind und prüft, ob es dort etwas zu aktualisieren gibt.
