Logback.xml配置

Question

我正在尝试配置stout以保存到文件中.但是,它没有保存到文件中 - 你知道为什么吗？另外 - 我希望日志文件名可以在logback.xml中配置,例如来自cmd的{LOG_FILE_NAME} - 是否可能？

这是我的logback.xml:

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

第二个答案：您必须使用 SIFT 附加程序来获取文件的系统参数。

 <appender name="SIFT" class="ch.qos.logback.classic.sift.SiftingAppender">
    <!-- in the absence of the class attribute, it is assumed that the desired 
        discriminator type is ch.qos.logback.classic.sift.MDCBasedDiscriminator -->
    <discriminator>
        <key>FILE_NAME</key>
        <defaultValue>DEFAULT_FILE_NAME</defaultValue>
    </discriminator>
    <sift>
        <appender name="FILE-${FILE_NAME}"
            class="ch.qos.logback.core.rolling.RollingFileAppender">
            <filter class="ch.qos.logback.core.filter.EvaluatorFilter">
                <evaluator> <!-- defaults to type ch.qos.logback.classic.boolex.JaninoEventEvaluator -->
                    <expression>return message.contains("Broken pipe");</expression>
                </evaluator>
                <OnMismatch>NEUTRAL</OnMismatch>
                <OnMatch>DENY</OnMatch>
            </filter>
            <File>${LOGDIR}/${FILE_NAME}.log</File>
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                <FileNamePattern>${LOGDIR}/${FILE_NAME}.%d{yyyy-MM-dd}.%i.log.gz
                </FileNamePattern>  <!-- keep 30 days' worth of history -->
                <MaxHistory>30</MaxHistory>
                <!-- Limit all logs size to 300MB -->
                <timeBasedFileNamingAndTriggeringPolicy
                    class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                    <!-- or whenever the file size reaches 10MB -->
                    <maxFileSize>10MB</maxFileSize>
                </timeBasedFileNamingAndTriggeringPolicy>
            </rollingPolicy>
            <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
                <Pattern>%date [%thread] %-5level %logger{36} - %msg%n</Pattern>
            </encoder>
        </appender>
    </sift>
</appender>
