java项目log4j配置

1.添加maven依赖

  <dependencies>
        <dependency>
            <groupId>log4j</groupId>
                <artifactId>log4j</artifactId>
            <version>1.2.17</version>
        </dependency>
    </dependencies>

2.代码中设置

import org.apache.log4j.Logger;

public class hello {
    static Logger logger = Logger.getLogger(hello.class);
    public static void main(String args[]) {
        logger.info("6666666666");
        logger.warn("44444444444444");
    }
}

3.配置log4j.properties

##########Set Log Levels###############
