说说在 logback 中如何输出与主日志不同的独立业务日志文件

首先定义好 appender，然后定义一个 logger 节点，引用刚才定义的appender。logger 节点有以下三个属性，具体说明如下。

完整示例如下：

<appender name="interceptorTimeFileOutput" class="ch.qos.logback.core.rolling.RollingFileAppender">
    
     
    
     <File>${LOG_HOME}/xx/interceptor.log</File>
    
     
    
     <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
    
     
    
     <FileNamePattern>${LOG_HOME}/xx/interceptor.%d{yyyy-MM-dd}.%i.log.gz</FileNamePattern>
    
     
    
     <MaxHistory>30</MaxHistory>
    
     
    
     <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
    
     <maxFileSize>10KB</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>
    
     
    
     <charset>UTF-8</charset>
    
     </encoder>
    
     </appender>
    
     <logger name="com.xxx.xx" level="INFO" additivity="false" >
    
     <appender-ref ref="interceptorTimeFileOutput"/>
    
     </logger>
