#输出sql语句到日志
log4j.logger.org.hibernate.SQL=debug
org.hibernate.SQL包及子包的日志输出级别为debug

以org.hibernate.SQL开头的类中报出来的错（通常来说，也可能是名称为org.hibernate.SQL开头的错），会被用log4j输出。。
区别在于声明方式。

Java代码

logger.getLog(Text.class);
logger.getLog("Text");

logger.getLog(Text.class);  logger.getLog("Text");

如果配置log4j.logger.Text=debug就会被输出。。
见http://www.blogjava.net/rickhunter/articles/28133.html

参考：
Best for Debugging
log4j.rootLogger=INFO, stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%c] %m%n

log4j.logger.httpclient.wire.header=DEBUG
log4j.logger.org.apache.commons.httpclient=DEBUG
