Question

当我使用以下附加程序时

<appender name="APPLICATION"
          class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>D:/logs/log.txt</file>
    <append>true</append>
    <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
        <Pattern>%p %d [%t] %L - %m%n</Pattern>
    </encoder>
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <!-- rollover daily -->
        <fileNamePattern>D:/logs/log.%d{yyyy-MM-dd}.%i.txt</fileNamePattern>
        <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
            <maxFileSize>10MB</maxFileSize>
        </timeBasedFileNamingAndTriggeringPolicy>
        <!-- keep 30 days' worth of history -->
        <maxHistory>30</maxHistory>
    </rollingPolicy>
</appender>

我收到以下警告：

SizeAndTimeBasedFNATP已弃用。使用SizeAndTimeBasedRollingPolicy 代替

所以我将SizeAndTimeBasedFNATP更改为SizeAndTimeBasedRollingPolicy

这让我有了：

<timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
        <maxFileSize>10MB</maxFileSize>
</timeBasedFileNamingAndTriggeringPolicy>

但是我得到：

未为名为RollingFileAppender的设置TriggeringPolicy 应用

这让我认为没有这样的TriggeringPolicy，所以我将TriggeringPolicy恢复为SizeAndTimeBasedFNATP，并将滚动策略从TimeBasedRollingPolicy更改为SizeAndTimeBasedRollingPolicy。

我的新的rollingPolicy现在变为：

<rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
        <!-- rollover daily -->
        <fileNamePattern>D:/logs/log.%d{yyyy-MM-dd}.%i.txt</fileNamePattern>
        <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
            <maxFileSize>10MB</maxFileSize>
        </timeBasedFileNamingAndTriggeringPolicy>
        <!-- keep 30 days' worth of history -->
        <maxHistory>30</maxHistory>
</rollingPolicy>

但是我得到：

TriggeringPolicy尚未启动。 RollingFileAppender无法启动

我试图在每个午夜或在达到最大大小后（以先到者为准）实现过渡。现在，我使用的是Logback版本：1.2.3

Answer 1

最终发现maxFileSize必须在timeBasedFileNamingAndTriggeringPolicy之外，而SizeAndTimeBasedRollingPolicy并不需要。因此，根据时间和大小（以先到者为准）滚动的最终logback.xml变为：

<?xml version="1.0" encoding="UTF-8"?>

<configuration>
    <!-- Send debug messages to System.out -->
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%p %d [%t] %L - %m%n</pattern>
        </encoder>
    </appender>
    <appender name="APPLICATION" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>D:/logs/log.txt</file>
        <append>true</append>
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <Pattern>%p %d [%t] %L - %m%n</Pattern>
        </encoder>
        <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
            <!-- rollover daily -->
            <fileNamePattern>D:/logs/log.%d{yyyy-MM-dd HH}.%i.txt</fileNamePattern>
            <maxFileSize>5GB</maxFileSize>
            <!-- keep 30 days' worth of history -->
            <maxHistory>30</maxHistory>
            <totalSizeCap>20GB</totalSizeCap>
        </rollingPolicy>
    </appender>

    <logger name="javaportreader" level="INFO" additivity="false">
        <appender-ref ref="STDOUT" />
    </logger>
    <logger name="application" level="DEBUG" additivity="false">
        <appender-ref ref="APPLICATION"/>
    </logger>

    <!-- By default, the level of the root level is set to DEBUG -->
    <root level="DEBUG">
        <appender-ref ref="STDOUT" />
    </root>
    <root level="INFO">
        <appender-ref ref="APPLICATION"/>
    </root>
</configuration>

从TimeBasedRollingPolicy移至SizeAndTimeBasedRollingPolicy，以每隔一个mignight或最大大小滚动一次
