logging - 从 TimeBasedRollingPolicy 移动到 SizeAndTimeBasedRollingPolicy 以在每个 mignight 或最大大小翻转

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 is deprecated. Use SizeAndTimeBasedRollingPolicy instead

所以我改了 SizeAndTimeBasedFNATP至 SizeAndTimeBasedRollingPolicy
这给我留下了这个:

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

但后来我得到:

No TriggeringPolicy was set for the RollingFileAppender named APPLICATION

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 更改为至 SizeAndTimeBasedRollingPolicy .

我的新滚动策略现在变为:

<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>

但后来我得到:

TriggeringPolicy has not started. RollingFileAppender will not start

我试图在每个午夜或最大尺寸之后实现翻转，以先到者为准。现在，我使用的是 logback 版本: 1.2.3

Answer 1

终于想通了maxFileSize必须在 timeBasedFileNamingAndTriggeringPolicy 之外和 SizeAndTimeBasedRollingPolicy不需要这个。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>
