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);
