Configure Log4j in Hibernate
Create a file named 'log4j.properties' under main project, where 'hibernate.cfg.xml' exists with following contents. This configuration will log sql in a file, the location you specified and also log in your project IDE console.
# Log everything. Good for troubleshooting
log4j.logger.org.hibernate=INFO
# Log all SQL DML statements as they are executed
log4j.logger.org.hibernate.SQL=TRACE
# Log all JDBC parameters(TRACE|INHERITED);
log4j.logger.org.hibernate.type=TRACE
log4j.logger.org.hibernate.hql.ast.AST=info
# Log all SQL DDL statements as they are executed(INHERITED|WARN)
log4j.logger.org.hibernate.tool.hbm2ddl=INHERITED
log4j.logger.org.hibernate.hql=debug
log4j.logger.org.hibernate.cache=info
log4j.logger.org.hibernate.jdbc=debug
# Log all second-level cache activity
log4j.logger.org.hibernate.cache=INHERITED
# Log all OSCache activity - used by Hibernate
log4j.logger.com.opensymphony.oscache=INHERITED
# Log transaction related activity
log4j.logger.org.hibernate.transaction=INHERITED
# Log all JDBC resource acquisition
log4j.logger.org.hibernate.jdbc=INHERITED
# Log all JAAS authorization requests
log4j.logger.org.hibernate.secure=INHERITED
# Root logger option
log4j.rootLogger=INFO, CUSTOM_FILE, CUSTOM_STD_OUT
# Define the file appender
log4j.appender.CUSTOM_FILE=org.apache.log4j.DailyRollingFileAppender
# Set the DatePattern (Every hour interval)
log4j.appender.CUSTOM_FILE.DatePattern='['yyyy-MM-dd-HH'].log'
# Set the DatePattern (Every minute interval)
#log4j.appender.CUSTOM_FILE.DatePattern='['yyyy-MM-dd-HH-mm'].log'
# Set the append to false, should not overwrite
log4j.appender.CUSTOM_FILE.Append=true
# Set the name of the file.
# It'll be created every hour/minute with different
# filename(appnded with yyyy-MM-dd-HH/yyyy-MM-dd-HH-mm).
log4j.appender.CUSTOM_FILE.File=C:/tmp/debug.log
# Define the layout for file appender
log4j.appender.CUSTOM_FILE.layout=org.apache.log4j.PatternLayout
log4j.appender.CUSTOM_FILE.layout.conversionPattern= %d{HH:mm:ss} %m%n
# Direct log messages to stdout
log4j.appender.CUSTOM_STD_OUT=org.apache.log4j.ConsoleAppender
log4j.appender.CUSTOM_STD_OUT.Target=System.out
log4j.appender.CUSTOM_STD_OUT.layout=org.apache.log4j.PatternLayout
log4j.appender.CUSTOM_STD_OUT.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
log4j.appender.CUSTOM_STD_OUT.layout.ConversionPattern=%d{ABSOLUTE} - %m%n
Execute following line of code when project start/run, before performing any CRUD operations:
ClassLoader loader = Thread.currentThread().getContextClassLoader();
URL url = loader.getResource("log4j.properties");
System.out.println(url);
PropertyConfigurator.configure(url);
You have to include log4j-1.2.16.jar in your project
When you perform query, output would be like this in your IDE consle:
/* When perform HQL */
10:30:29,149 - HQL: SELECT MIN(id) FROM com.pkm.domains.User
/* When perform SQL */
10:30:29,149 - SQL: select min(user0_.id) as col_0_0_ from User user0_
10:30:29,149 - throwQueryException() : no errors
10:30:29,191 - select min(user0_.id) as col_0_0_ from User user0_ limit ?
10:30:29,226 - Found [14] as column [col_0_0_]
10:30:29,228 - select user0_.id as id0_0_, user0_.date_updated as date2_0_0_, user0_.email as email0_0_, user0_.first_name as first4_0_0_, user0_.last_name as last5_0_0_, user0_.phone_number as phone6_0_0_, user0_.area_code as area7_0_0_ from User user0_ where user0_.id=?
10:30:29,230 - binding parameter [1] as [BIGINT] - 14
10:30:29,238 - Found [2014-05-10 10:23:08.0] as column [date2_0_0_]
10:30:29,238 - Found [pritomkucse@gmail.com] as column [email0_0_]
10:30:29,238 - Found [Pritom] as column [first4_0_0_]
10:30:29,239 - Found [Kumar Mondal] as column [last5_0_0_]
/* Update Query */
10:30:29,261 - update User set date_updated=?, email=?, first_name=?, last_name=?, phone_number=?, area_code=? where id=?
10:30:29,262 - binding parameter [1] as [TIMESTAMP] - Sat May 10 10:30:29 ALMT 2014
