Question

我必须将文件：log4j配置从版本1转换为2。但它必须是一对一的。此操作后的日志必须与log4j版本1完全相同。

你能帮我把它从log4j 1转换成log4j2 ....

<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
    <appender name="mylog" class="org.apache.log4j.RollingFileAppender">
        <param name="File" value="mylog.log"/>
        <param name="RollingPolicy" value="org.apache.log4j.rolling.TimeBasedRollingPolicy"/>
        <param name="ActiveFileName" value="mylog.log"/>
        <param name="FileNamePattern" value="mylog-%d{yyyyMMdd-HHmm}.rolled"/>
        <param name="TriggeringPolicy" value="org.apache.log4j.rolling.SizeBasedTriggeringPolicy"/>
        <param name="maxFileSize" value="100000"/>
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%d{ISO8601} [%t] %p - %m%n"/>
        </layout>
    </appender>
    <logger name="mylogger" additivity="false">
        <level value="DEBUG"/>
        <appender-ref ref="mylog"/>
    </logger>
    <root>
        <level value="DEBUG"/>
        <appender-ref ref="sysoutlog"/>
    </root>
</Configuration>

我相信这就是你要找的东西：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xml> <!-- I use this just to get rid of eclipse XML schema warning -->
<Configuration status="warn" name="My configuration"> <!-- Modify status to get more verbose info -->
<Appenders>
    <RollingFile name="mylog" fileName="mylog.log"
        filePattern="mylog-%d{yyyyMMdd-HHmm}.rolled">
        <PatternLayout>
            <pattern>%d{ISO8601} [%t] %p - %m%n</pattern>
        </PatternLayout>
        <Policies>
            <SizeBasedTriggeringPolicy size="100KB" />
        </Policies>
    </RollingFile>
</Appenders>
<Loggers>
    <Logger name="mylogger" level="debug" additivity="false">
        <AppenderRef ref="mylog" />
    </Logger>
    <Root level="debug">
        <AppenderRef ref="sysoutlog" />
    </Root>
</Loggers>
</Configuration>

有关更多格式选项，请参阅Docs of layout configuration。此外，如果您打算将根记录器转发到控制台，我会添加此appender

<Console name="STDOUT" target="SYSTEM_OUT" />

并将root logger的appender更改为

<AppenderRef ref="STDOUT" />

将log4j转换为log4j2。使用RollingFileAppender，大小和文件名模式
