日志相关的配置可以通过xml文件来配置

默认配置是resource目录下的logback.xml也可以通过logging.file指定配置文件

日志配置主要有几种配置

1.  按日期切割成不同的文件
    
        
            <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
                <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                    
                    <FileNamePattern>${LOG_HOME}/client-demo.log.%d{yyyy-MM-dd}.%i.log</FileNamePattern>
                    
                    <maxHistory>30</maxHistory>
                    
                    <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                        <maxFileSize>1KB</maxFileSize>
                    </timeBasedFileNamingAndTriggeringPolicy>
                </rollingPolicy>
                <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
                    
                    <pattern>[%d{yyyy-MM-dd HH:mm:ss.SSS}] [%thread] %-5level %logger{50} - %msg%n</pattern>
                </encoder>
            </appender>
2.  按大小切割成不同的文件
    
        
                    <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                        <maxFileSize>1KB</maxFileSize>
                    </timeBasedFileNamingAndTriggeringPolicy>
3.  异步日志输出
    
        
            <appender name="ASYNC-FILE" class="ch.qos.logback.classic.AsyncAppender">
                
                <discardingThreshold>0</discardingThreshold>
                
                <queueSize>200</queueSize>
                
                <appender-ref ref="FILE"/>
            </appender>
4.  错误日志邮件通知
    
        
            <property name="smtpHost" value="smtp.qq.com"/>
            <property name="smtpPort" value="587"/>
            <property name="mailFrom" value="xxxx@qq.com"/>
            <property name="username" value="xxxx@qq.com"/>
            <property name="password" value="xxxxx"/>
            <property name="mailTo" value="xxxxx@qq.com"/>
            <property name="SSL" value="false"/>
            <property name="mailSubject" value="日志测试"/>
            <appender name="MAIL" class="ch.qos.logback.classic.net.SMTPAppender">
                <smtpHost>${smtpHost}</smtpHost>
                <smtpPort>${smtpPort}</smtpPort>
                <username>${username}</username>
                <password>${password}</password>
                <SSL>${SSL}</SSL>
                <asynchronousSending>false</asynchronousSending>
                <to>${mailTo}</to>
                <from>${mailFrom}</from>
                <subject>${mailSubject}</subject>
                <layout class="ch.qos.logback.classic.html.HTMLLayout">
                    <Pattern>[%d{yyyy-MM-dd HH:mm:ss.SSS}] [%thread] %-5level %logger{50} - %msg %n</Pattern>
                </layout>
                <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
                    <level>ERROR</level>
                </filter>
            </appender>

QQ邮箱的密码的获取是在邮箱设置里面

异步日志可以在启动程序之后看到多了一个异步日志的线程，在异步线程的方法里面打上断点，打印的时候会进入该断点
