Java 在Spring Boot web应用程序中嵌入Tomcat配置lo4j2日志记录

我已成功将我的Spring Boot web应用程序配置为使用log4j2，配置文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN" monitorInterval="30">
<Properties>
    <Property name="LOG_PATTERN">
        %d{yyyy-MM-dd HH:mm:ss.SSS} %5p ${hostName} --- [%15.15t] %-40.40c{1.} : %m%n%ex
    </Property>
</Properties>
<Appenders>
    <Console name="ConsoleAppender" target="SYSTEM_OUT" follow="true">
        <PatternLayout pattern="${LOG_PATTERN}"/>
    </Console>
    <RollingFile name="FileAppender" fileName="${env:LEM_HOME}/Logs/LEM.log" 
                 filePattern="${env:LEM_HOME}/Logs/LEM-%d{yyyy-MM-dd}-%i.log">
        <PatternLayout>
            <Pattern>${LOG_PATTERN}</Pattern>
        </PatternLayout>
        <Policies>
            <SizeBasedTriggeringPolicy size="10MB" />
        </Policies>
        <DefaultRolloverStrategy max="10"/>
    </RollingFile>
</Appenders>
<Loggers>
    <Logger name="com.mdenis.labequipmentmanager" level="debug" additivity="false">
        <AppenderRef ref="ConsoleAppender" />
        <AppenderRef ref="FileAppender" />
    </Logger>
    <Logger name="org.apache.tomcat" level="debug" additivity="false">
        <AppenderRef ref="ConsoleAppender" />
        <AppenderRef ref="FileAppender" />
    </Logger>
    <Logger name="org.springframework" level="debug" additivity="false">
        <AppenderRef ref="ConsoleAppender" />
        <AppenderRef ref="FileAppender" />
    </Logger>
    <Logger name="org.hibernate" level="info" additivity="false">
        <AppenderRef ref="ConsoleAppender" />
        <AppenderRef ref="FileAppender" />
    </Logger>
    <Root level="error">
        <AppenderRef ref="ConsoleAppender"/>
    </Root>
</Loggers>
</Configuration>

%d{yyyy-MM-dd HH:MM:ss.SSS}%5p${hostName}-[%15.15t]-40.40c{1.}:%m%n%ex
${LOG_PATTERN}

我知道它是有效的，因为当应用程序启动时，将Spring的日志级别设置为debug会给我提供大约一百万个日志条目。以下是POM.XML文件供参考：

我唯一不能做的就是将Tomcat设置为调试级别。通过这些设置，我还可以将Hibernate设置为调试模式，因此我相信Tomcat有一些特定的功能

是否有一种方法可以使用log4j2控制Tomcat嵌入式日志级别，就像我在其他框架中所做的那样

谢谢

我搜索了更多，找到了如何做到这一点。您需要将其添加到运行的java-jar命令中：

-Djava.util.logging.manager=org.apache.logging.log4j.jul.LogManager

由于某些原因，日志级别的更改不能像我使用自己的记录器那样以编程方式完成，因此您必须将其放入log4j2.xml文件中：

    <Logger name="org.apache" level="debug" additivity="false">
        <AppenderRef ref="ConsoleAppenderWebClient" />
        <AppenderRef ref="FileAppenderWebClient" />
    </Logger>
