以maven web项目为例，
首先、在pom文件引入相关依赖，如下（spring官网文档有介绍）：
<dependencies>
<!-- spring 相关 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>4.0.2.RELEASE</version>
<exclusions>
<exclusion>
<groupId>commons-logging</groupId>
<artifactId>commons-logging</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>jcl-over-slf4j</artifactId>
<version>1.5.8</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.5.8</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.5.8</version>
</dependency>
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.14</version>
</dependency>
</dependencies>
spring 内部默认使用的日志框架是： commons-logging（需排除该依赖）， 引入“jcl-over-slf4j”依赖，使spring对common-logging的调用转为对slf4j的调用，
需要注意的是： 排除commons-logging依赖后，若不配置其他替代依赖（jcl-over-slf4j），容器初始化时会报错：java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
接着编写log4j配置文件log4j.xml，位于classpath路径下（src/main/resources）
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration PUBLIC "-//APACHE//DTD LOG4J 1.2//EN" "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
<!-- Appenders -->
<appender name="FILE" class="org.apache.log4j.RollingFileAppender">
<param name="file" value="${project.home}/logs/dispatchmanage.log" />
<param name="append" value="true" />
<param name="maxFileSize" value="100MB" />
<param name="maxBackupIndex" value="10" />
<layout class="org.apache.log4j.PatternLayout">
<param name=‘ConversionPattern‘ value=‘[%-5p][%d{yyyy/MM/dd HH:mm:ss}][%l][%m]%n‘ />
</layout>
</appender>
<appender name="Console" class="org.apache.log4j.ConsoleAppender">
<param name="Target" value="System.out" />
<layout class="org.apache.log4j.PatternLayout">
<param name=‘ConversionPattern‘ value=‘[%-5p][%d{yyyy/MM/dd HH:mm:ss}][%l][%m]%n‘ />
</layout>
</appender>
<!-- Application Loggers -->
<logger name="com.hgs">
<level value="debug" />
<appender-ref ref="FILE" />
</logger>
<!-- 3rdparty Loggers -->
<logger name="org.springframework.core">
<level value="info" />
</logger>
<logger name="org.springframework.beans">
<level value="info" />
</logger>
<logger name="org.springframework.context">
<level value="info" />
</logger>
<logger name="org.springframework.web">
<level value="info" />
</logger>
<!-- SQL Loggers -->
<logger name="java.sql.Statement" additivity="true">
<level value="debug" />
</logger>
<logger name="java.sql.PreparedStatement" additivity="true">
<level value="debug" />
</logger>
<logger name="com.ibatis">
<level value="info" />
</logger>
<logger name="com.ibatis.common.jdbc">
<level value="info" />
</logger>
<logger name="com.ibatis.sqlmap.engine.impl">
<level value="info" />
</logger>
<logger name="java.sql.Connection">
<level value="info" />
</logger>
<!-- Root Logger -->
<root>
<level value="debug" />
<appender-ref ref="Console" />
</root>
</log4j:configuration>
到此所有的配置工作就完成了，紧接着就可以在实际代码中编程使用了，如下：
package com.yinz.tool.quartz.test;
import java.util.Date;
import org.quartz.Job;
import org.quartz.JobDataMap;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
/**
*
* @description:调度任务要执行的具体操作，
* 该类必须要有一个无参构造器
* @author yinz
* 2016-7-7
*/
public class SimpleJob implements Job {
private Logger logger = LoggerFactory.getLogger(SimpleJob.class);
public void execute(JobExecutionContext context) throws JobExecutionException {
//JobDataMap dataMap = context.getJobDetail().getJobDataMap(); //JobDetail中的JobDataMap
JobDataMap dataMap = context.getMergedJobDataMap(); //trigger和JobDetail的中的JobDataMap的合并
String jobMsg = dataMap.getString("jobMsg");
String triggerMsg = dataMap.getString("triggerMsg");
logger.info(new Date() + " : < " + jobMsg + " >, < " + triggerMsg + " >" );
}
}
代码中可以看出，我们是面向slf4j 的api编程，这样就可以方便实现在不同的日志框架间切换而不需修改代码。
