把日志調(diào)試設(shè)置為true，需要log4j.properties配置文件支持

log4j.properties

### 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.net.sf.hibernate=info

### log just the SQL
#log4j.logger.net.sf.hibernate.SQL=debug

### log JDBC bind parameters 把這一行改為debug ###
log4j.logger.net.sf.hibernate.type=debug

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

### log cache activity ###
#log4j.logger.net.sf.hibernate.cache=debug

### log jdbc resource acquisition
#log4j.logger.net.sf.hibernate.impl.BatcherImpl=debug

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