Question

我将日志记录从同步更改为异步，但是我不确定如何在其中设置策略。我想将同步日志记录设置应用于异步日志记录。请参见下面。

// I switched from this 

<RollingFile name="fileLogger" fileName="${logPath}/log.log"
                 filePattern="${logPath}/log-%d{yyyy-MM-dd-hh}-%i.log">
        <PatternLayout>
            pattern="${logPattern}"/>
        </PatternLayout>
        <Policies>
            <OnStartupTriggeringPolicy/>
            <SizeBasedTriggeringPolicy size="10 MB"/>
        </Policies>
        <DefaultRolloverStrategy max="5"/>
    </RollingFile>
</Appenders>

//to this 

<File name="prodLog" fileName="${logPath}/log.log">
        <PatternLayout
                pattern="${logPattern}"/>
    </File>
    <Async name="asyncLogger" includeLocation="true">
        <AppenderRef ref="prodLog"/>
        <ArrayBlockingQueue/>
    </Async>

我认为您不能对文件追加程序使用相同的策略。要实现滚动文件的异步行为，可以使用RollingRandomAccessFile，如以下示例所示：

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="debug">
    <Appenders>
        <Console name="Console-Appender" target="SYSTEM_OUT">
            <PatternLayout>
                <pattern>
                    [%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n
                </pattern>>
            </PatternLayout>
        </Console>
        <RollingRandomAccessFile name="Rolling-Random-Access-File-Appender"
                                 fileName="logs/rollingrandomaccessfile.log"
                                 filePattern="archive/logs/rollingrandomaccessfile.log.%d{yyyy-MM-dd-hh-mm}.gz">
            <PatternLayout pattern="[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n"/>
            <Policies>
                <SizeBasedTriggeringPolicy size="1 KB"/>
            </Policies>
            <DefaultRolloverStrategy max="30"/>
        </RollingRandomAccessFile>

    </Appenders>
    <Loggers>
        <AsyncLogger  name="guru.springframework.blog.log4j2async" level="debug">
            <AppenderRef ref="Rolling-Random-Access-File-Appender"/>
        </AsyncLogger>
        <Root level="debug">
            <AppenderRef ref="Console-Appender"/>
        </Root>
    </Loggers>
</Configuration>
