回滚日志文件大小和时间

问题描述

我一直在尝试建立一个简单的 logback 项目来按日期和文件大小滚动我的日志文件，到目前为止我一直无法让我的 appender 滚动到另一个文件.相反，它写入由 <file/> 指定的日志.标签.

I've been trying to set up a simple logback project to roll my log files by date and by filesize, and so far I have been unable to get my appender to roll over to another file. Instead, it writes to the log specified by the <file/> tag.

这是我的 logback.xml 配置文件:

Here is my logback.xml configuration file:

<?xml version="1.0"?>
<configuration scan="true" scanPeriod="10 seconds">
    <appender name="stdout" class="ch.qos.logback.core.ConsoleAppender">
        <layout class="ch.qos.logback.classic.PatternLayout">
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger - %msg%n</pattern>
        </layout>
    </appender>

    <appender name="milliroller" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>log/output.log</file>
        <layout class="ch.qos.logback.classic.PatternLayout">
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger - %msg%n</pattern>
        </layout>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>log/mylog-%d{yyyy-MM-dd}.%i.txt</fileNamePattern>
            <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <maxFileSize>1KB</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy>
        </rollingPolicy>
    </appender>

    <root level="DEBUG">
        <appender-ref ref="stdout"/>
        <appender-ref ref="milliroller"/>
    </root>

    <logger name="com.tkassembled.logback" level="DEBUG"/>
</configuration>

乍一看，它应该可以工作，对吧?有什么我做错了吗?我的整个可构建项目在此处以 zip 格式提供:http://www.mediafire.com/file/2bxokkdyz2i/logback.zip

At first glance, it looks like it should work, right? Is there something I'm doing wrong? My entire, buildable project is available in a zip here: http://www.mediafire.com/file/2bxokkdyz2i/logback.zip

推荐答案

虽然这是一个老问题，但我觉得一个有效的答案适合帮助任何需要这种实现的人.

Although this is an old question, I felt that a working answer is appropriate to help anyone who requires this kind of implementation.

我使用以下 logback 配置来提供 HTML 日志，按日期和文件大小滚动，以及记录到控制台以进行调试输出.

I use the following logback configuration to provide an HTML log, rolled over by date and filesize, as well as logging to console for debugging output.

日志文件存储在 logs 目录中，其名称为 logFile.html 当它处于活动状态时，logFile.2013-mm-dd.i.html 当它翻转时，其中 i 是 50MB 日志文件的数量.例如 logFile.2013-01-07.0.html.

Logfiles are stored in a logs directory with a name of logFile.html while its active, and logFile.2013-mm-dd.i.html when it rolls over, where i is the number of 50MB log files. For instance logFile.2013-01-07.0.html.

<configuration>

  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <!-- encoders are assigned the type
         ch.qos.logback.classic.encoder.PatternLayoutEncoder by default -->
    <encoder>
      <charset>UTF-8</charset>
      <pattern>%d{HH:mm:ss.SSS} [%thread] %highlight(%-5level) %cyan(%logger{35}) - %msg %n</pattern>
    </encoder>
  </appender>

  <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>logslogFile.html</file>
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
      <!-- daily rollover -->
      <fileNamePattern>logslogFile.%d{yyyy-MM-dd}.%i.html</fileNamePattern>
      <timeBasedFileNamingAndTriggeringPolicy
          class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
          <!-- or whenever the file size reaches 50MB -->
        <maxFileSize>50MB</maxFileSize>
      </timeBasedFileNamingAndTriggeringPolicy>
      <!-- keep 30 days' worth of history -->
      <maxHistory>30</maxHistory>
    </rollingPolicy>
    <encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder">
      <charset>UTF-8</charset>
      <layout class="ch.qos.logback.classic.html.HTMLLayout">
        <pattern>%d{HH:mm:ss.SSS}%thread%level%logger%line%msg</pattern>
      </layout>
    </encoder>
  </appender>

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

</configuration>
