3.log4j日志

1.加入依赖

<dependency>

  <groupId>log4j</groupId>

  <artifactId>log4j</artifactId>

  <version>1.2.17</version>

</dependency>

2.在resouce下新建log4j.properties文件

log4j.rootLogger=DEBUG, INFO, ERROR, CONSOLE

log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.Threshold=INFO
log4j.appender.CONSOLE.Target=System.out
log4j.appender.CONSOLE.Encoding=UTF-8
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=[%p]%d{yyyy-MM-dd HH:mm:ss} %l -  %m%n


log4j.appender.INFO = org.apache.log4j.DailyRollingFileAppender
log4j.appender.INFO.File = G:/log/messagePush_info.log

log4j.appender.INFO.Append = true
log4j.appender.INFO.Threshold = INFO
log4j.appender.INFO.Encoding=gbk
log4j.appender.INFO.layout = org.apache.log4j.PatternLayout
log4j.appender.INFO.layout.ConversionPattern = [%p] %d{yyyy-MM-dd HH:mm:ss} %l - %m%n


log4j.appender.ERROR = org.apache.log4j.DailyRollingFileAppender
log4j.appender.ERROR.File = G:/log/messagePush_error.log

log4j.appender.ERROR.Append = true
log4j.appender.ERROR.Threshold = ERROR
log4j.appender.ERROR.Encoding=UTF-8
log4j.appender.ERROR.layout = org.apache.log4j.PatternLayout
log4j.appender.ERROR.layout.ConversionPattern = [%p] %d{yyyy-MM-dd HH:mm:ss} %l - %m%n

3.配置完上面信息后就可以创建一个Java文件去测试日志的文件的使用了
