[java]slf4j+log4j日志框架

配置所需maven依赖

   <dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-api</artifactId>
      <version>1.7.9</version>
    </dependency>
    <dependency>
      <groupId>log4j</groupId>
      <artifactId>log4j</artifactId>
      <version>1.2.17</version>
    </dependency>
    <dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-log4j12</artifactId>
      <version>1.7.19</version>
    </dependency>

在resources下配置log4j.properties文件

log4j.debug=true
#配置根logger
log4j.rootLogger=DEBUG,stdout,D,E
#附着器  日志输出目的地
#控制台输出
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=[%d{yyyy-MM-dd HH:mm:ss}] [%5p] [%c{1}:%L] : %m%n
#%d{ABSOLUTE}
log4j.appender.E=org.apache.log4j.DailyRollingFileAppender
log4j.appender.E.File = D:/logs/logs.log
log4j.appender.E.Append = true
log4j.appender.E.Threshold = DEBUG
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
#log4j.appender.E.layout


log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = D:/logs/error.log
log4j.appender.D.Append = true
#指定日志消息的输出最低层次
log4j.appender.D.Threshold = ERROR
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

这样就可以完成基本的使用了
