Question

我的Log4j2配置文件如下所示：

printSomething()

班级<Appenders> <RollingRandomAccessFile name="APP_LOG_APPENDER" fileName="${sys:baseLogPath}/${appLogFileName}.log" filePattern="${sys:baseLogPath}/backups/$${date:yyyy-MM}/${appLogFileName}-%d{yyyy-MM-dd}-%i.log.gz" immediateFlush="false"> <PatternLayout> <Pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [Thread: %t] %level [%c][%M] - %msg%n</Pattern> </PatternLayout> <Policies> <TimeBasedTriggeringPolicy /> <SizeBasedTriggeringPolicy size="50 MB" /> </Policies> <DefaultRolloverStrategy max="20"/> </RollingRandomAccessFile> </Appenders> <Loggers> <Root level="debug" additivity="false"> <AppenderRef ref="APP_LOG_APPENDER" /> </Root> </Loggers>

中的记录器语句

MyClass

日志消息显示为：

public class MyClass {
  private final static org.slf4j.Logger logger = org.slf4j.LoggerFactory.getLogger(MyClass.class);
  public void someMethod() {
    logger.debug("Some sample string at DEBUG level....");
    logger.info("Some sample string at INFO level....");
    logger.warn("Some sample string at WARN level....");
    logger.error("Some sample string at ERROR level....");
  }
}

我使用的是log4j2-2.5版本和相应的SLF4J API。

有人可以帮我理解为什么会这样吗？

对我来说，下一个配置运行良好（未启用includeLocation="true"选项）：

src / main / resources / log4j2.xml

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
    <Properties>
        <Property name="PID">%5X{pid}</Property>
        <Property name="LOG_EXCEPTION_CONVERSION_WORD">%xEx</Property>
        <Property name="LOG_LEVEL_PATTERN">%5p</Property>
        <Property name="LOG_PATTERN">%style{%d{yyyy-MM-dd HH:mm:ss.SSS}}{dim} %highlight{${LOG_LEVEL_PATTERN}} %style{${sys:PID}}{magenta} %style{---}{dim} %style{[%15.15t]}{dim} %style{%-40.40c{1.}}{cyan} %style{%22.22M}{magenta} %style{:}{faint} %m%n${sys:LOG_EXCEPTION_CONVERSION_WORD}</Property>
    </Properties>
    <Appenders>
        <Console name="ConsoleAppender" target="SYSTEM_OUT" follow="true">
            <PatternLayout pattern="${LOG_PATTERN}" />
        </Console>
    </Appenders>
    <Loggers>
        <logger name="com.github.daggerok" level="ALL" additivity="false">

        </logger>
        <Root level="ALL">
            <AppenderRef ref="ConsoleAppender"/>
        </Root>
    </Loggers>
</Configuration>

build.gradle

dependencies {

    implementation 'org.apache.logging.log4j:log4j-api'

为什么log4j 2不记录应用程序和单元测试的方法名称
