摘要：本文主要介绍了如何在spring、springMVC中使用logback

## 一、logback与Spirng结合使用 ##

1、maven添加引用：

<dependency>
    			<groupId>log4j</groupId>
    			<artifactId>log4j</artifactId>
    			<version>${log4j.version}</version>
    		</dependency>
    		<dependency>
    			<groupId>org.slf4j</groupId>
    			<artifactId>slf4j-api</artifactId>
    			<version>${slf4j.version}</version>
    		</dependency>
    		<dependency>
    			<groupId>ch.qos.logback</groupId>
    			<artifactId>logback-classic</artifactId>
    			<version>1.1.2</version>
    		</dependency>
    		<dependency>
    			<groupId>ch.qos.logback</groupId>
    			<artifactId>logback-core</artifactId>
    			<version>1.1.2</version>
    		</dependency>
    		<dependency>
    			<groupId>org.logback-extensions</groupId>
    			<artifactId>logback-ext-spring</artifactId>
    			<version>0.1.1</version>
    		</dependency>

其中logback-ext-spring这个jar包是为了和spring一起使用的。

2、src/main/resource添加logback.xml

其中，下面这几个参数 是在pom.xml里配置的，如果你不想在pom.xml里来配置，也可以直接写死就是

参数内容如下：

<profiles>
    		
    		<profile>
    			<id>dev</id>
    			<activation>
    				<activeByDefault>true</activeByDefault>
    			</activation>
    			
    			<properties>
    				
    				<jdbc_driverClassName>com.mysql.jdbc.Driver</jdbc_driverClassName>
    				<jdbc_url>jdbc:mysql://localhost:3306/learning</jdbc_url>
    				<jdbc_username>root</jdbc_username>
    				<jdbc_password>christmas258@</jdbc_password>
    
    				<log.moduleName>ssm-project</log.moduleName>
    				<log.base>logs</log.base>
    				<log.other.level>DEBUG</log.other.level>
    				<log.root.level>DEBUG</log.root.level>
    				<log.stdout.ref><![CDATA[<appender-ref ref="stdout" />]]></log.stdout.ref>
    			</properties>
    		</profile>
    	</profiles>

3、如果单独的跑一个spring项目，不带web页面的话，那么这时跑个单元测试就可以打印日志了

看看输出的文件：

## 二、logback与spingMVC结合使用 ##

其实与spingMVC只需要在上面的工程中，在web.xml里添加如下内容即可。

<context-param>
    		<param-name>logbackConfigLocation</param-name>
    		<param-value>classpath:logback.xml</param-value>
    	</context-param>
    	<listener>
    		<listener-class>ch.qos.logback.ext.spring.web.LogbackConfigListener</listener-class>
    	</listener>

**然后本地启动tomcat，把项目加载进来，注意，此时的日志输出路径 不会像上面一样出现在工程所在路径的logs目录下，而会放在eclipse安装目录下，自动新建一个logs目录 下：**

![20160205145038847][]

**而如果将此war包上传到linux下的tomcat的webapp目录后，日志文件会保存在tomcat/bin/logs目录下，记得，这个是web项目和非web项目日志保存路径的不同！**

下面这一个是配置比较复杂的，大的工程更多的是以这种方式来配置的，针对不同的包，不同级别的日志来分别打印，如下：

<?xml version="1.0" encoding="UTF-8"?>
    <configuration>
    	
    	<property name="log.root.level" value="${log.root.level}" /> 
    	<property name="log.other.level" value="${log.other.level}" />

    	<appender name="file.all" class="ch.qos.logback.core.rolling.RollingFileAppender">

    			</FileNamePattern>
    			
    			<timeBasedFileNamingAndTriggeringPolicy
    				class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
    				<maxFileSize>${log.max.size}</maxFileSize>
    			</timeBasedFileNamingAndTriggeringPolicy>
    		</rollingPolicy>
    		
    		<layout class="ch.qos.logback.classic.PatternLayout">
    			<pattern>%date{yyyy-MM-dd HH:mm:ss.SSS} %-5level[%thread]%logger{56}.%method:%L -%msg%n</pattern>
    		</layout>
    	</appender>
    	
    	
    	<appender name="file.all.other" class="ch.qos.logback.core.rolling.RollingFileAppender">
    		<File>${log.base}/${log.moduleName}_other.log</File>

    		</rollingPolicy>
    		<layout class="ch.qos.logback.classic.PatternLayout">
    			<pattern>%date{yyyy-MM-dd HH:mm:ss.SSS} %-5level [%thread] %logger{56}.%method:%L -%msg%n</pattern>
    		</layout>
    	</appender>
    
    	
    	<appender name="file.error"

    		<filter class="ch.qos.logback.classic.filter.LevelFilter">

    		</filter>
    	</appender>
    
       
        
        
    	<appender name="file.async" class="ch.qos.logback.classic.AsyncAppender">
    		<discardingThreshold>0</discardingThreshold>
    		<queueSize>256</queueSize>
