log4j使用与个人配置

在mybatis中，这样设置

    <settings>
        <setting name="logImpl" value="LOG4J"/>
    </settings>

配置log4j.properties

#//注意这里不要用INFO，DEBUG等 改个名字
log4j.rootLogger=infoA,errorA,stdout,DEBUGA

#过滤掉spring框架下的额外日志
log4j.category.org.springframework = WARN

#输出到控制台
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.Threshold = debug
log4j.appender.stdout.layout.ConversionPattern=%d %-5p %c{1}:%L - %m%n

#输出error到指定文件
log4j.logger.errorA=error
log4j.appender.errorA=org.apache.log4j.DailyRollingFileAppender
log4j.appender.errorA.layout=org.apache.log4j.PatternLayout
log4j.appender.errorA.layout.ConversionPattern=%d{yyyy-MM-dd-HH-mm} [%t] [%c] [%p] - %m%n
log4j.appender.errorA.datePattern=yyyy-MM-dd'.log'
log4j.appender.errorA.Threshold = error
log4j.appender.errorA.append=true
log4j.appender.error.File=d:/java/log4j/error.log

#输出DEBUG信息到指定文件
log4j.logger.DEBUGA=DEBUG
log4j.appender.DEBUGA=org.apache.log4j.DailyRollingFileAppender
log4j.appender.DEBUGA.layout=org.apache.log4j.PatternLayout
log4j.appender.DEBUGA.layout.ConversionPattern=%d{yyyy-MM-dd-HH-mm} [%t] [%c] [%p] - %m%n
log4j.appender.DEBUGA.datePattern=yyyy-MM-dd'.log'
log4j.appender.DEBUGA.Threshold = DEBUG
log4j.appender.DEBUGA.append=true
log4j.appender.DEBUGA.File=d:/java/log4j/debug_log.log

#打印sql语句
log4j.logger.com.ibatis=DEBUG
log4j.logger.java.sql.ResultSet=INFO
log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=DEBUG
log4j.logger.com.ibatis.common.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

 默认配置如下

# Set root category priority to INFO and its only appender to CONSOLE.
#log4j.rootCategory=INFO, CONSOLE            debug   info   warn error fatal
log4j.rootCategory=info, CONSOLE, LOGFILE

# Set the enterprise logger category to FATAL and its only appender to CONSOLE.
log4j.logger.org.apache.axis.enterprise=FATAL, CONSOLE

# CONSOLE is set to be a ConsoleAppender using a PatternLayout.
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPatern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n
t
# LOGFILE is set to be a File appender using a PatternLayout.
log4j.appender.LOGFILE=org.apache.log4j.FileAppender
log4j.appender.LOGFILE.File=d:\axis.log
log4j.appender.LOGFILE.Append=true
log4j.appender.LOGFILE.layout=org.apache.log4j.PatternLayout
log4j.appender.LOGFILE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n
