SSM框架引入logback日志框架

1、本章主要结合实例描述如何在SpringMVC框架中引入logback日志框架，关于常见的几种日志框架的介绍和性能对比大家可以自行去了解。

2、整合logback：

2.1、jar包引入，logback-ext-spring为spring支持jar

<dependency>
                <groupId>ch.qos.logbackgroupId>
            <artifactId>logback-classicartifactId>
            <version>1.1.2version>
        dependency>

        <dependency>
            <groupId>ch.qos.logbackgroupId>
            <artifactId>logback-coreartifactId>
            <version>1.1.2version>
        dependency>

        <dependency>
            <groupId>org.logback-extensionsgroupId>
            <artifactId>logback-ext-springartifactId>
            <version>0.1.1version>
        dependency>

2.2、web.xml中配置监听器，param-name的配置参考WebLogBackConfigurer类

<context-param>
        <param-name>logbackConfigLocationparam-name>
        <param-value>classpath:logback.xmlparam-value>
    context-param>

    <listener>
        <listener-class>ch.qos.logback.ext.spring.web.LogbackConfigListenerlistener-class>
    listener>

2.3、配置日志相关属性logback.xml，关于详细的配置可以参考一篇博客，里面讲的很详细：l logback.xml

项目在D盘，这里配置的日志输出路径是：D:\local\logs\..，目录在项目启动时会自动创建

xml version="1.0" encoding="UTF-8"?>
<configuration>

    <property name="log.root.level" value="DEBUG" />
    <property name="log.other.level" value="ERROR" />
    <property name="log.base" value="/local/logs" />
    <property name="log.moduleName" value="dubbo-provider" />
    <property name="log.max.size" value="20MB" />


    <appender name="stdout" class="ch.qos.logback.core.ConsoleAppender">
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <Pattern>%date{yyyy-MM-dd HH:mm:ss.SSS} %-5level [%thread]%logger{56}.%method:%L -%msg%nPattern>
        encoder>
    appender>


    <appender name="file" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <File>${log.base}/${log.moduleName}.logFile>

        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <FileNamePattern>${log.base}/archive/${log.moduleName}_all_%d{yyyy-MM-dd}.%i.log.zip
            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%npattern>
        layout>
    appender>


    <logger name="com.dubbo.provider" additivity="false">
        <level value="debug" />
        <appender-ref ref="stdout" />
        <appender-ref ref="file" />
    logger>

    <root level="debug">
        <appender-ref ref="stdout" />
        <appender-ref ref="file" />
    root>
configuration>

3、启动项目，如果有输出日志则说明配置成功，可以根据项目需求修改logback.xml参数
