SSM下log4j2 记录日志

SSM环境下使用log4j2  需导入包

<dependency>
	  <groupId>org.apache.logging.log4j</groupId>
	  <artifactId>log4j-core</artifactId>
	  <version>2.9.0</version>
	</dependency>
	<dependency>
	  <groupId>org.apache.logging.log4j</groupId>
	  <artifactId>log4j-slf4j-impl</artifactId>
	  <version>2.9.0</version>
	</dependency>

在classpath下需创建log4j2.xml

<?xml version="1.0" encoding="UTF-8"?>
<!--设置log4j2的自身log级别为DEBUG-->
<configuration status="DEBUG ">

    <appenders>
    	<!-- 控制台输出 -->
        <console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss} [%t] %-5level %logger{36} - %n%msg%n"/>
        </console>

		<!-- fileName：输出路径  filePattern：命名规则 -->
        <RollingFile name="RollingFileInfo" fileName="D:\\demo\\allOut.log"
                     filePattern="D:\\demo\\$${date:yyyy-MM-dd}/allOut-%d{yyyy-MM-dd}-%i.log.gz">

        </RollingFile>

    <loggers>
        <!--过滤掉spring和hibernate的一些无用的debug信息-->
        <logger name="org.springframework" level="INFO">

简单的日志控制基类

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

/**
 * 日志记录基类
 * @author Administrator
 *
 */
public abstract class BaseLogController {

	private static Logger logger = LogManager.getLogger();

	public BaseLogController() {
	}

	//级别从高到低：FATAL、ERROR、WARN、INFO、DEBUG、TRACE
	public void fatal(Object message){
		logger.fatal(message);
	}
	public void error(Object message){
		logger.error(message);
	}
	public void warn(Object message){
		logger.warn(message);
	}
	public void info(Object message){
		logger.info(message);
	}
	public void debug(Object message){
		logger.debug(message);
	}
	public void trace(Object message){
		logger.trace(message);
	}
