02-在mybatis中使用log4j记录日志信息

1.导包

​ 除了mybatis和jdbc连接所需包之外的jar包，将他们加入到项目中

2. 加入log4j配置文件

​ 在src下加入log4j.properties配置文件

#设置日志级别
# Set root category priority to INFO and its only appender to CONSOLE.
log4j.rootCategory=DEBUG, CONSOLE  
#log4j.rootCategory=INFO, CONSOLE, LOGFILE
#局部调整日志级别
#log4j.logger.com.mapper.UserMapper.selAll=DEBUG

# Set the enterprise logger category to FATAL and its only appender to CONSOLE.
log4j.logger.org.apache.axis.enterprise=FATAL
#日志打印到控制台上的相关信息设置
# 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.ConversionPattern=- %m %c %l  %d{yyyy-MM-dd HH:mm:ss}%n
#日志存储到硬盘上的相关信息设置
# LOGFILE is set to be a File appender using a PatternLayout.
log4j.appender.LOGFILE=org.apache.log4j.FileAppender
log4j.appender.LOGFILE.File=E:/ABC.log
log4j.appender.LOGFILE.Append=true
log4j.appender.LOGFILE.Threshold=DEBUG
log4j.appender.LOGFILE.layout=org.apache.log4j.PatternLayout
log4j.appender.LOGFILE.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m %d{yyyy-MM-dd HH:mm:ss}%n
