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 像{LOG_FILE_NAME}这样来自cmd的东西 - 有可能吗?
这是我的logback.xml:
<?xml version="1.0" encoding="UTF-8"?>

第一个答案,请点击此处: https://github.com/abdulwaheed18/Slf4jTutorial
第二个答案:您必须使用SIFT appender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>

<File>
节点应全部为小写字母。所以,而不是
<File>sarit_test.log</File>
应该是
<file>sarit_test.log</file>
这是您所犯的错误之一,尝试修复它(可能会解决问题),下次请将错误消息附加到您的问题中。

可以在命令行设置属性,如:
java -DUSER_HOME="/home/sebastien" MyApp2
您还可以在系统级别设置这些属性。 LogBack将首先查看配置属性,然后查看java系统属性,然后查看系统属性。
使用以下配置将STDOUT写入控制台和文件:
<configuration>
<!-- LOG_FILE_NAME: Java system properties set on the command line -->
<!-- LOG_HOME: Set at this line below -->
<property name="LOG_HOME" value="/home/sebastien" />
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%date %-5level [%thread] - [%logger]- %msg%n</pattern>
</encoder>
</appender>
<appender name="FILE" class="ch.qos.logback.core.FileAppender">
<file>${LOG_HOME}/${LOG_FILE_NAME}</file>
<encoder>
<pattern>%date %-5level [%thread] - [%logger] - %msg%n</pattern>
</encoder>
</appender>
<root level="WARN">
<appender-ref ref="STDOUT" />
<appender-ref ref="FILE" />
</root>
</configuration>

我立即看到的一件事是你只打开了<rollingPolicy>
,但政策本身是空的。我打赌这会产生一些问题。
对于问题的第二部分,是的,这是可能的,最简单的方法可能是定义一个“常量”,其值将由应用程序中的类设置。
我已经重新设计了你的logback.xml以包含上面的两个建议。我意识到这已经有一年了,但对于寻找类似问题的其他人来说,它仍然有用。
<configuration>
<define name="logPath" class="path.to.your.Class.with.public.method.getLogPath">
<key>getLogPath</key>
</define>
<appender name="defaultLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
<!--See also http://logback.qos.ch/manual/appenders.html#RollingFileAppender-->
<File>${logPath}${file.separator}sarit_test.log</File>
<encoder>
<pattern>%d{dd MMM yyyy HH:mm:ss.SSS} [%t] %-5p %x %F:%L - %m</pattern>
</encoder>
<rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy"/>
<fileNamePattern>${logPath}${file.separator}sarit_test.log.%i.zip</fileNamePattern>
<minIndex>1</minIndex>
<maxIndex>5</maxIndex>
</rollingPolicy>
<triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
<MaxFileSize>50000KB</MaxFileSize>
</triggeringPolicy>
</appender>
<root level="INFO">
<appender-ref ref="defaultLog"/>
</root>
</configuration>

<configuration>
<!-- LOG_FILE_NAME: Java system properties set on the command line -->
<!-- LOG_HOME: Set at this line below -->
<property name="LOG_HOME" value="/home/sebastien" />
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%date %-5level [%thread] - [%logger]- %msg%n</pattern>
</encoder>
</appender>
<appender name="FILE" class="ch.qos.logback.core.RollingFileAppender">
<file>${LOG_HOME}/${LOG_FILE_NAME}</file>
<encoder>
<pattern>%date %-5level [%thread] - [%logger] - %msg%n</pattern>
</encoder>
</appender>
<root level="WARN">
<appender-ref ref="STDOUT" />
<appender-ref ref="File" />
</root>
</configuration>
这可以很好地写入文件和控制台
