**最新logback.xml文件内容：**

<?xml version="1.0" encoding="UTF-8"?>
    <configuration>
    	
    	
    	<appender name="stdout"
    		class="ch.qos.logback.core.ConsoleAppender">
    		<encoder>
    			<pattern>%d [%t] [%c] [%p] (%file:%line\)- %m%n</pattern>
    			<charset>UTF-8</charset>
    		</encoder>
    	</appender>
    	
    	<appender name="baselog"
    		class="ch.qos.logback.core.rolling.RollingFileAppender">
    		<File>log/run.log</File>
    		<rollingPolicy
    			class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
    			<fileNamePattern>log/run.log.%d.%i</fileNamePattern>
    			<timeBasedFileNamingAndTriggeringPolicy
    				class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
    				
    				<maxFileSize>64 MB</maxFileSize>
    			</timeBasedFileNamingAndTriggeringPolicy>
    			
    			<maxHistory>7</maxHistory>
    		</rollingPolicy>
    		<encoder>
    			<pattern>
    				%d [%t] [%c] [%p] - %m%n
    			</pattern>
    			<charset>UTF-8</charset> 
    		</encoder>
    	</appender>
    	
    	<appender name="async_file" class="ch.qos.logback.classic.AsyncAppender" 
    		immediateFlush="false" neverBlock="true">
    		
    		<discardingThreshold>0</discardingThreshold>
    		
    		<queueSize>1024</queueSize>
    		<appender-ref ref="baselog" />
    	</appender>
    	<root level="INFO">
    		<appender-ref ref="stdout" />
    	</root>
    	
    	<logger name="com.md" level="DEBUG">
    		<appender-ref ref="async_file" />
    	</logger>
    </configuration>

> 注意：配置了async\_file部分，使用异步AsyncAppender对象配置

默认队列大小queueSize是256，见源码：
