Turning off hibernate logging console output

Question

I'm using hibernate 3 and want to stop it from dumping all the startup messages to the console. I tried commenting out the stdout lines in log4j.properties but no luck. I've pasted my log file below. Also I'm using eclipse with the standard project structure and have a copy of log4j.properties in both the root of the project folder and the bin folder.

### direct log messages to stdout ###
#log4j.appender.stdout=org.apache.log4j.ConsoleAppender
#log4j.appender.stdout.Target=System.out
#log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
#log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

### direct messages to file hibernate.log ###
log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=hibernate.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

### set log levels - for more verbose logging change 'info' to 'debug' ###

log4j.rootLogger=warn, stdout

#log4j.logger.org.hibernate=info
log4j.logger.org.hibernate=debug

### log HQL query parser activity
#log4j.logger.org.hibernate.hql.ast.AST=debug

### log just the SQL
#log4j.logger.org.hibernate.SQL=debug

### log JDBC bind parameters ###
log4j.logger.org.hibernate.type=info
#log4j.logger.org.hibernate.type=debug

### log schema export/update ###
log4j.logger.org.hibernate.tool.hbm2ddl=debug

### log HQL parse trees
#log4j.logger.org.hibernate.hql=debug

### log cache activity ###
#log4j.logger.org.hibernate.cache=debug

### log transaction activity
#log4j.logger.org.hibernate.transaction=debug

### log JDBC resource acquisition
#log4j.logger.org.hibernate.jdbc=debug

### enable the following line if you want to track down connection ###
### leakages when using DriverManagerConnectionProvider ###
#log4j.logger.org.hibernate.connection.DriverManagerConnectionProvider=trac5

Answer 1

Try to set more reasonable logging level. Setting logging level to info means that only log event at info or higher level (warn, error and fatal) are logged, that is debug logging events are ignored.

log4j.logger.org.hibernate=info

or in XML version of log4j config file:

<logger name="org.hibernate">
  <level value="info"/> 
</logger>

See also log4j manual.

You can disabled the many of the outputs of hibernate setting this props of hibernate (hb configuration) a false:

hibernate.show_sql
hibernate.generate_statistics
hibernate.use_sql_comments

But if you want to disable all console info you must to set the logger level a NONE of FATAL of class org.hibernate like Juha say.

I changed the "debug" to "info" and it worked. Here is what I did:

Before: log4j.rootLogger=debug, stdout, R After: log4j.rootLogger=info, stdout, R
