slf4j 和 log4j合用的（Maven)配置

1. 在Maven的porn.xml 文件中添加dependency如下

<dependency>  
    <groupId>org.slf4j</groupId>  
    <artifactId>slf4j-log4j12</artifactId>  
    <version>1.7.2</version>  
</dependency> 

之后就会添加三个包，

2. 之后在项目下添加log4j.properties

项目路径如下，

log4j.properties

#config root logger  
log4j.rootLogger = INFO,system.out  
log4j.appender.system.out=org.apache.log4j.ConsoleAppender  
log4j.appender.system.out.layout=org.apache.log4j.PatternLayout  
log4j.appender.system.out.layout.ConversionPattern=MINAServer Logger-->%5p{%F:%L}-%m%n  

#config this Project.file logger  
log4j.logger.thisProject.file=INFO,thisProject.file.out  
log4j.appender.thisProject.file.out=org.apache.log4j.DailyRollingFileAppender  
log4j.appender.thisProject.file.out.File=logContentFile.log  
log4j.appender.thisProject.file.out.layout=org.apache.log4j.PatternLayout  

5、代码中使用：

private static final Logger logger = LoggerFactory.getLogger(MINAServer.class);
