Logback日志配置：

1. logback-access 第三方软件可以访问这个日志
2. logback-classic 可以方便更换其他日志系统
3. logback-core核心文件

• logback.xml文件如下配置

<?xml version="1.0" encoding="utf-8" standalone="no"?>
<configuration debug="false">
	<appender name="INFO-FILE"
		class="ch.qos.logback.core.rolling.RollingFileAppender">
		<file>${catalina.base}/webapps/myo2o/logs/info/info.log</file>
		<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
			<fileNamePattern>${catalina.base}/webapps/myo2o/logs/info/info.%d{yyyy-MM-dd}.%i.log.zip</fileNamePattern>
			<timeBasedFileNamingAndTriggeringPolicy
				class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
				<maxFileSize>1024MB</maxFileSize>
			</timeBasedFileNamingAndTriggeringPolicy>
			<maxHistory>30</maxHistory>
		</rollingPolicy>
		<layout class="ch.qos.logback.classic.PatternLayout">
			<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{55} -
				%msg%n
			</pattern>
		</layout>
	</appender>
	<appender name="ACCESS-FILE"
		class="ch.qos.logback.core.rolling.RollingFileAppender">
		<file>
			${catalina.base}/webapps/myo2o/logs/access/access.log</file>
		<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
			<FileNamePattern>${catalina.base}/webapps/myo2o/logs/access/access.%d{yyyy-MM-dd}.%i.log.zip</FileNamePattern>
			<timeBasedFileNamingAndTriggeringPolicy
				class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
				<maxFileSize>1024MB</maxFileSize>
			</timeBasedFileNamingAndTriggeringPolicy>
			<maxHistory>30</maxHistory>
		</rollingPolicy>
		<layout class="ch.qos.logback.classic.PatternLayout">
			<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{55} -
				%msg%n
			</pattern>
		</layout>
	</appender>
	<logger name="com.imooc.myo2o" level="DEBUG" additivity="false">
		<appender-ref ref="ACCESS-FILE" />
	</logger>
	<root level="INFO">
		<appender-ref ref="INFO-FILE" />
	</root>
</configuration>

然后一般在services层或者controller层设置logback日志

Logger logger = LoggerFactory.getLogger(AreaController.class);

logger.info("可以写信息啦")

logger.debug调优一般可以加上startTime-endTime

logger.error 错误信息
