（求助）如何在tomcat中关闭sql刷屏

以前开过tomcat中刷sql，现在感觉系统好慢，请问怎么关闭啊？找不到当时的帖子了

这是log4j的文件，请问我该怎么改呀

### set log levels - for more verbose logging change 'info' to 'debug' ###
log4j.rootLogger=INFO, stdout, E

### 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

###log message to daily file##
log4j.appender.E = org.apache.log4j.DailyRollingFileAppender
log4j.appender.E.File=myapps_error.log
log4j.appender.E.Append=true
log4j.appender.E.Threshold=WARN
log4j.appender.E.datePattern='.'yyyy-MM-dd
log4j.appender.E.layout = org.apache.log4j.PatternLayout
log4j.appender.E.layout.ConversionPattern =%d{ABSOLUTE} %5p %c{1}:%L - %m%n - [ %t:%r ]

#log4j.logger.org.hibernate=INFO
log4j.logger.org.hibernate=WARN

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

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

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

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

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

### 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=trace

# OpenSymphony Stuff
log4j.logger.com.opensymphony=ERROR
log4j.logger.com.opensymphony.webwork=ERROR

# Spring Stuff
log4j.logger.org.springframework=ERROR

# Platform Stuff
log4j.logger.cn.myapps=DEBUG

经协助，将第二行log4j.rootLogger=INFO, stdout, E注释掉，并将hibernate.properties中的hibernate.format_sql设置为false后解决问题，谢谢~
