java项目配置了log4j之后，为什么一个小小的查询，就输出这么多的内容，以前也是这样配置的，并没有这么多内容呀？

Question

请输入代码# Rules reminder:
# DEBUG < INFO < WARN < ERROR < FATAL

# Global logging configuration
log4j.rootCategory=DEBUG,stdout,logfile
# My logging configuration...


## Console output...
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p %d %C: %m%n

log4j.logger.org.apache.ibatis=DEBUG
## log4j.logger.org.apache.jdbc.SimpleDataSource=DEBUG
log4j.logger.org.apache.ibatis.jdbc.ScriptRunner=DEBUG
## log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapclientDelegate=DEBUG
log4j.logger.java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG

Answer 1

log4j.rootCategory=DEBUG,stdout,logfile

改成

log4j.rootCategory=WARN,stdout,logfile

就少了
