logback - 有没有办法在 logback 中为单个日志文件定义多个滚动策略？

Question

我正在尝试设置一个 logback 配置，该配置创建一个解压缩的日志文件作为第一卷，然后将压缩文件写入不同的目录。我相信最好的方法是在单个 appender 中创建多个 rollingPolicy 元素。任何人都可以指导我举一个有人成功做到这一点的例子吗？

<configuration>
  <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>test.log</file>

    <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
      <fileNamePattern>tests.%i.log</fileNamePattern>
      <minIndex>1</minIndex>
      <maxIndex>1</maxIndex>
    </rollingPolicy>

    <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
      <fileNamePattern>archives/tests.%i.log.zip</fileNamePattern>
      <minIndex>2</minIndex>
      <maxIndex>5</maxIndex>
    </rollingPolicy>

    <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
      <maxFileSize>5MB</maxFileSize>
    </triggeringPolicy>
    <encoder>
      <pattern>%-4relative [%thread] %-5level %logger{35} - %msg%n</pattern>
    </encoder>
  </appender>

  <root level="DEBUG">
    <appender-ref ref="FILE" />
  </root>
</configuration>

这是如何做到的:

<!-- Time and Size based: Roll every day and split big file in smaller peaces -->
<appender name="ROOT" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>${LOG_HOME}/root.log</file>
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
           <fileNamePattern>${OTHER_HOME}/root-%d{yyyy-MM-dd}.%i.log.zip</fileNamePattern>
           <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <maxFileSize>10MB</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy>
            <maxHistory>10</maxHistory>
    </rollingPolicy>
    <encoder>
         <pattern>%date %-5level [%thread] - %mdc{loginName} - [%logger]- %msg%n</pattern>
    </encoder>
</appender>

${LOG_HOME} 是您的第一个目录

${OTHER_HOME} 用于压缩文件
