Hibernate Log4j 설정.

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

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

가장 많이 쓰일듯 싶다. 실행된 쿼리문을 로그로 찍는것과.. 넘어온 파라미터 값을 확인할 수 있다.

### log just the SQL (hibernate.cfg.xml 설정과 겹친다. hibernate.show_sql = false 한다.)
log4j.logger.org.hibernate.SQL=debug

### log JDBC bind parameters ### (log4j 1.2.15 쓰는데.. debug로 하면 안나오더라..)
log4j.logger.org.hibernate.type=TRACE

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

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

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

### 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=trace
