1.先说业务日志

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <jmxConfigurator/>
    <property name="log.path" value="/home/noahfund/dx/logs" /> 
    <property name="PATTERN" value="%d{yyyy-MM-dd HH:mm:ss.SSS} %level [kdsale,%X{traceId},%X{spanId},true] [%thread] [%c.%M:%L] - %message%n" />
    
    <!-- 控制台输出  -->
    <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">

        </encoder>
    </appender>
        
    <logger name="org.springframework" level="INFO" additivity="false">

    <logger name="com.szkingdom.jros.core.web.controller" level="INFO" additivity="false">

    <!--系统框架 -->

    <logger name="com.szkingdom.jros.core.engine.unmarshaller" level="WARN" additivity="false">

    </logger>
    <logger name="com.szkingdom" level="INFO" additivity="false">
        <appender-ref ref="FILE_BUSINESS" />    
    </logger>

    <root level="INFO">     
        <appender-ref ref="CONSOLE" />
        <appender-ref ref="FILE_ERROR" />
        <appender-ref ref="FILE_BUSINESS" />
    </root> 
</configuration>

2.如果是tomcat的日志需要安装插件cronolog或者利用系统本身的定时任务做切割。
