Salut,

Comment afficher les valeurs utilisées, à la place des points d'interrogation, dans les requêtes éxécutées par Hibernate (quand on fait <property name="show_sql">true</property> pour afficher les requêtes dans hibernate.xml) ?
Apparemment c'est à paramétrer dans log4j.properties...

Merci.

[fr1man]

Exactement, c'est avec log4j qu'il faut le faire.
Tu trouveras un exemple de fichier log4j dans l'archive hibernate, me semble-t-il.

[bumbo500]

effectivement c'est dans le fichier log4j de ton appliaction ; il faut simplement rajouter la ligne :
log4j.logger.org.hibernate.type = DEBUG, stdout

Attention car cette ligne génère beaucoup de log et rsique de ralentir quelque peu ton appli.

Ca donnerait quoi dans un fichier xml (log4j.xml) ?

[cdubet]

1) log4j fait des traces dans un fichier qui n est pas au format xml.
le fichier de conf de log4j est xml

2) si tu veux savoir ce qu envoie hibernate a la base de donne je te conseille plutot p6spy
Ca te fait un fichier log avec uniquement les commandes sql.
en plus tu peux avoir une GUI qui te donne les temps d execution de tes commandes

Tu mets dans ton hibernate.cfg quelque chose comme ca
<!-- to log all the jdbc commands -->
<property name="hibernate.connection.driver_class">com.p6spy.engine.spy.P6SpyDriver</property>

<!-- oracle driver direct for ex
<property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>

# This feature detects long-running statements that may be indicative of

# When this feature is enabled, no other statements are logged except the long

# For example, if this is set to 2, then any statement requiring at least 2
# seconds will be logged. Note that the same statement will continue to be logged
# for as long as it executes. So if the interval is set to 2, and the query takes

Je me répète un peu, mais avec l'archive Hibernate est (ou était mais je doute que ce ne soit plus le cas) fourni un exemple de fichier de conf log4j pour afficher les logs.
Il suffit de choisir le degré de détail que l'on souhaite voir affiché.
Il y a un paramètre bien précis pour les variables de requêtes mais je ne le connais pas de tête. Il est cependant suffisamment explicite.

Bonjour à tous,

J'utilise Spring Hibernate..Aprés avoir essayé dans log4j.properties, "log4j.logger.org.hibernate=debug,stdout", pour afficher les valeurs à la place des points d'interrogations pour afficher ma requête,celà ne fonctionne PAS.

Pourquoi?Comment y remédier?

Merci

[tatia34]

bonjour, je me trouve devant le même soucis...

je souhaierais afficher les valeurs à la place des ?, mais l'ajout de ligne log4j.logger.org.hibernate=debug,stdout dans le fichier log4j.properties ne change pas les ? et ajoute toutefois plus de lignes de debug...

est-ce que quelqu'un pourrait me donner un exemple ou encore dire où se trouve l'exemple dans l'archive hibernate (j'ai bien regardé un peu, mais moyennement envie de passer tous les dossiers un par un...)

merci d'avance
