Bonjour tout le monde...

j'ai un petit souci avec log4j, J'utilise Hibernate, et je souhaiterais voir les requetes qu'il génére, pour cela, j'ai ecrit un fichier log4j.properties afin d'effectuer la journalisation:


log4j.rootCategory=error, console
log4j.category.ApplicationInitialisation=debug, R
log4j.category.Queries=debug, Q

#### ecrire dans la console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.SimpleLayout

#### ecrire dans un fichier l'initialisation
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=initialise.log
# Controle de la taille maximal du fichier
log4j.appender.R.MaxFileSize=2048KB
# Archive log files (one backup file here)
log4j.appender.R.MaxBackupIndex=5
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %d - %m%n

#### ecrire dans un fichier les requetes
log4j.appender.Q=org.apache.log4j.RollingFileAppender
log4j.appender.Q.File=Requete.log
# Controle de la taille maximal du fichier
log4j.appender.Q.MaxFileSize=2048KB
# Archive log files (one backup file here)
log4j.appender.Q.MaxBackupIndex=5
log4j.appender.Q.layout=org.apache.log4j.PatternLayout
log4j.appender.Q.layout.ConversionPattern=%p %t %c - %m%n


j'importe le fichier de cette façonc la:

PropertyConfigurator.configure("C:\\....\\log4j.properties");

Aprés le lancement de l'appli, il creer bien les deux fichiers:
-requete.log
-initialise.log

Mais ils sont vide...
Si quelqu'un a vu mon erreur, et peut me corriger...
Merci beaucoup...

Hello,
Utilises-tu dans ton code java le logger ?? Sinon c'est clair que tes logs sont vides.


private static final Logger LOG = Logger.getLogger(<Nom de la classe>.class);
LOG.info("ton message");

[cofy]

Salut,

Effectivement, je n'utilise pas le Logger dans mon code!!!

private static final Logger LOG = Logger.getLogger(<Nom de la classe>.class);
LOG.info("ton message");

Cette façon permet de logger des infos, ou des erreurs, perso, c'est des requetes que je voudrais journaliser, faut t'il que j'utilise la démarche que tu ma montrer??


Merci...

[Fr@ncky]

Si tu veux qu'hibernate de montre les requêtes hibernate tu peux simplement ajouter la propriétép suivante dans le fichier hibernate.cfg.xml

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1

3
 
<!-- properties -->
<property name="show_sql">true</property>

Si tu veux que ton application "logge" des informations, utiliser le logger dans tes classes (ce qui est "normal").

[cofy]

oui, c'est une autre méthode, mais le souci c'est que les requetes ne sont afficher que dans la console... Et le jour où l'appli plante en production, on ne saura pas quelle requete à posée un probleme...

[Lafab]

j'ai enfin reussi a créer un fichier de log

voici l'erreur :
