logback在名称为当前日期的文件夹中创建日志文件 [英] logback create log files inside folder having name as current date

问题描述

在我当前的项目中，我希望日期创建日志文件，即日志文件应位于名称为日期的

文件夹中。
此外，归档应该发生在该特定文件夹中。

In my current project i want to create log files date wise i.e. log files should reside inside
folder having name as date. Also archiving should happen at that particular folder.

我使用的当前appender看起来像这样（它根据大小存档日志文件）。 / p>

Current appender that i am using looks like this (it does archiving of log file based on size).

    <appender name="AUDITFILE"
    class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>${PROJECT_HOME}\\projectname\\audits\\myproject.log</file>
    <append>true</append>
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <fileNamePattern>${PROJECT_HOME}\\projectname\\audits\\myproject_%d{yyyy-MM-dd}.%i.zip
        </fileNamePattern>
        <maxHistory>10</maxHistory>
        <timeBasedFileNamingAndTriggeringPolicy
            class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
            <maxFileSize>10KB</maxFileSize>

        </timeBasedFileNamingAndTriggeringPolicy>
    </rollingPolicy>
    <encoder>
        <pattern>%date %msg%n
        </pattern>
    </encoder>
</appender>

推荐答案

如 fileNamePattern ，您可以指定多个％d标记，以便将日期放在存档文件名的文件夹名称中：

As mentioned in the documentation for fileNamePattern, you can specify multiple %d tokens so as put the date in the folder name of the archive filename:

<fileNamePattern>${PROJECT_HOME}\\projectname\\audits\\%d{yyyy-MM, aux}\\myproject_%d{yyyy-MM-dd}.%i.zip</fileNamePattern>

请注意，只有一个％d标记可以是主标记，所有其他标记必须通过传递标记为辅助标记'aux'参数。

Note that only one %d token can be primary, all other tokens must be marked as auxiliary by passing the 'aux' parameter.

但是如果你还想把它放在非档案文件名的文件名中，那么你有两个选择：

But if you also want to put it in the file name of the non-archive filename, then you have two options:

1. 使用< timestamp /> 元素设置您在路径中使用的变量。但是这个时间戳只会在启动时设置一次，所以它对批量运行有好处，但不适用于服务。

1. use a <timestamp /> element to set a variable which you use in the path. But this timestamp will only be set once at startup, so it's good for batch runs but not for services.

如上所述（1），但包装< appender /> 和< timestamp /> 带有 SiftingAppender ，如果使用logback> = 1.0.12的版本，将启用时间戳重新评估。不确定您要如何配置 SiftingAppender 。但希望这会让你走上正轨。

Do like (1) above, but wrap the <appender/> and the <timestamp /> with a SiftingAppender, which will enable the timestamp to be re-evaluated, if using version of logback >=1.0.12. Not sure exactly how you'd want to configure the SiftingAppender. But hopefully that will put you on the right track.
