导入log4j.jar
设置日志级别等相关内容
文件内容(仅控制台有效):
### 设置###
log4j.rootLogger = debug,stdout,D,E
### 输出信息到控制抬 ###
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 = [%-5p] %d{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n
### 输出DEBUG 级别以上的日志到=E://logs/error.log ###
###log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
###log4j.appender.D.File = E://logs/log.log
###log4j.appender.D.Append = true
###log4j.appender.D.Threshold = DEBUG
###log4j.appender.D.layout = org.apache.log4j.PatternLayout
###log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n
### 输出ERROR 级别以上的日志到=E://logs/error.log ###
###log4j.appender.E = org.apache.log4j.DailyRollingFileAppender
###log4j.appender.E.File =E://logs/error.log
###log4j.appender.E.Append = true
###log4j.appender.E.Threshold = ERROR
###log4j.appender.E.layout = org.apache.log4j.PatternLayout
###log4j.appender.E.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n
