log4j2无法创建信息级别日志

Question

我的spring boot应用程序中有Log4j2，我希望将事件记录到2个日志文件中。用户服务无法创建信息级别的日志，但可以创建警告级别的日志。有人能指点一下吗？

Log4j2.xml

<Configuration>
    <Appenders>
        <RollingFile name="matchFile"
            fileName="${log-path}/match.log"
            immediateFlush="true">
            <Filters>
                <ThresholdFilter level="trace" onMAtch="deny" onMismatch="neutral" />
                <ThresholdFilter level="debug" onMAtch="deny" onMismatch="neutral" />
                <ThresholdFilter level="info" onMAtch="accept" onMismatch="deny" />
                <ThresholdFilter level="warn" onMAtch="deny" onMismatch="neutral" />
                <ThresholdFilter level="error" onMAtch="deny" onMismatch="neutral" />
                <ThresholdFilter level="fatal" onMAtch="deny" onMismatch="neutral" />
            </Filters>
        </RollingFile>
        <RollingFile name="confirmFile"
            fileName="${log-path}/confirm.log"
            immediateFlush="true">
            <Filters>
                <ThresholdFilter level="trace" onMAtch="deny" onMismatch="neutral" />
                <ThresholdFilter level="debug" onMAtch="deny" onMismatch="neutral" />
                <ThresholdFilter level="info" onMAtch="deny" onMismatch="neutral" />
                <ThresholdFilter level="warn" onMAtch="accept" onMismatch="deny" />
                <ThresholdFilter level="error" onMAtch="deny" onMismatch="neutral" />
                <ThresholdFilter level="fatal" onMAtch="deny" onMismatch="neutral" />
            </Filters>
        </RollingFile>
    </Appenders>
</Configuration>

UserService.java

public class UserService{
    Logger matchLogger = LogManager.getLogger("matchFile");
    Logger confirmLogger = LogManager.getLogger("confirmFile");
    
    public void log(){
        matchLogger.info("print info"); //not able to log this message
        confirmLogger.warn("print warn"); //able to log this message
    }
}

你漏掉了<代码>

您的配置应如下所示：

<Configuration>
    <Appenders>
        <RollingFile name="matchFile"
            fileName="${log-pathmatchFile}/match.log"
            immediateFlush="true">
            <Filters>
                <!-- deny warn, error and fatal messages -->
                <ThresholdFilter level="warn" onMatch="deny" onMismatch="neutral" />
                <!-- accept info, warn, error, fatal and deny debug, trace -->
                <ThresholdFilter level="info" onMatch="accept" onMismatch="deny" />
            </Filters>
        </RollingFile>
        <RollingFile name="confirmFile"
            fileName="${log-path}/confirm.log"
            immediateFlush="true">
            <Filters>
                <!-- deny error and fatal messages -->
                <ThresholdFilter level="error" onMatch="deny" onMismatch="neutral" />
                <!-- accept warn, error, fatal and deny info, debug, trace -->
                <ThresholdFilter level="warn" onMatch="accept" onMismatch="deny" />
            </Filters>
        </RollingFile>
    </Appenders>
    
    <Loggers>
        <!-- probably declare the root logger level and appenders:
            <Root level="...">
                <AppenderRef ref="..." />
            </Root>
        -->
        <Logger name="matchFile" level="info">
            <AppenderRef ref="matchFile" />
        </Logger>
        <Logger name="confirmFile" level="warn">
            <AppenderRef ref="confirmFile" />
        </Logger>
    </Loggers>
</Configuration>
