Question

我在类路径中添加了jar apache-log4j-extras-1.1.jar和log4j-1.2.15.jar，在log4j.properties中没有配置。没有错误，但无法在日志文件中打印。我也提到了stackoverflow的问题，但它对我不起作用。任何有关它的建议将不胜感激。

如果使用rolling.RollingFileAppender，则log4j.properties中是否需要配置

的log4j.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
    <appender name="ASYNC" class="org.apache.log4j.AsyncAppender">
        <param name="BufferSize" value="256"/>
        <appender-ref ref="CONSOLE" />
        <appender-ref ref="DROLLFILE" />

    </appender>
    <appender name="CONSOLE" class="org.apache.log4j.ConsoleAppender">
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern"
                value="%d{yyyy/MM/dd HH:mm:ss,SSS} %-5p %c %x - %m %n" />
        </layout>
    </appender>
    <appender name="DROLLFILE" class="org.apache.log4j.rolling.RollingFileAppender" >
     <param name="threshold" value="DEBUG"/>
     <rollingPolicy name="file"  
                      class="org.apache.log4j.rolling.TimeBasedRollingPolicy">
        <param name="FileNamePattern" 
               value="/media/mgs1032/57403571-7065-47b8-88cd-1b20a9229764/ezeClick/ezeClickSetUp/PaymentGateWorkSpace/libs/logger/logs/ezeClick.log.%d{yyyy-MM-dd}.gz"/>
        <param name="ActiveFileName" value="/media/mgs1032/57403571-7065-47b8-88cd-1b20a9229764/ezeClick/ezeClickSetUp/PaymentGateWorkSpace/libs/logger/logs/ezeClick.log"/>
     </rollingPolicy>
     <layout class="org.apache.log4j.EnhancedPatternLayout" >
        <param name="ConversionPattern" 
               value="%d{ISO8601} %-5p - %-26.26c{1} - %m%n" />
    </layout>
  </appender>


    <logger name="amex.quickpay" additivity="false">
        <level value="debug" />
        <appender-ref ref="ASYNC" />
    </logger>
    <root>
        <priority value="info" />
        <appender-ref ref="ASYNC" />
    </root>

</log4j:configuration>

你的代码真的没什么问题，但是这对我有用（没有log4.properties）

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="error" monitorInterval="30" strict="true">

    <Properties>
        <Property name="log-path">${sys:catalina.base}/logs/</Property>
        <Property name="filename">appName.log</Property>
    </Properties>

    <Appenders>
        <RollingFile name="RollingFile" fileName="${log-path}/${filename}" filePattern="${log-path}/${filename}-%d{yyyy-MM-dd}-%i.log">
            <Layout type="PatternLayout" pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n" />
            <Policies>
                <OnStartupTriggeringPolicy />
                <TimeBasedTriggeringPolicy />
                <SizeBasedTriggeringPolicy size="5 MB" />
            </Policies>
            <DefaultRolloverStrategy max="10" />
        </RollingFile>
    </Appenders>

    <Loggers>
        <Root level="info">
            <AppenderRef ref="RollingFile" />
        </Root>
    </Loggers>

</Configuration>

编辑：注意：这是针对log4j 2

配置org.apache.log4j.rolling.RollingFileAppender
