Appuim项目实战—log4j配置

1. 在maven中配置log4j的依赖

1. <!-- 配置log4j依赖 -->  
2.         <dependency>  
3.             <groupId>log4j</groupId>  
4.             <artifactId>log4j</artifactId>  
5.             <version>1.2.17</version>  
6.         </dependency>  

在src新建一个log4j.properties内容如下

log4j.rootLogger=DEBUG,console,FILE

log4j.rootLogger=info,stdout,tracelog

log4j.appender.Root.Encoding=UTF-8

log4j.additivity.org.apache=false

log4j.appender.tracelog=org.apache.log4j.FileAppender

log4j.appender.tracelog.Encoding=UTF-8

log4j.appender.tracelog.File=./log/project.log

log4j.appender.D.Threshold = DEBUG ## 输出DEBUG级别以上的日志

log4j.appender.tracelog.layout=org.apache.log4j.PatternLayout

log4j.appender.tracelog.layout.ConversionPattern=%d{yyyy-MM-dd-HH:mm:ss}(%F:%L)%m%n

 

log4j.appender.stdout=org.apache.log4j.ConsoleAppender

log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

log4j.appender.stdout.layout.ConversionPattern=%-5p%d{yyyy-MM-dd-HH:mm:ss}(%F:%L)%m%n

　　

实例log

package until;

import org.apache.log4j.Logger;

import org.apache.log4j.PropertyConfigurator;

public class logTest {

    public static Logger logger = Logger.getLogger(logTest.class);

    public logTest() {  

        PropertyConfigurator.configure("log4j.properties");

    }

    public static void logInfo(Object message) {

        logger.info(message);

    }

    public static void logError(Object message) {

        logger.error(message);

        // Assert.assertTrue(false);可以扩展讲下，断言的几种方式

    }

    public static void logWarn(Object message) {

        logger.warn(message);

    }

}

　　

使用log

package until;

public class test {

public static void main(String[] args) {

    logTest.logInfo("12");

}

}

　　

 

效果如图
