Log4j2-环境查找失败-环境名称未追加到文件名中

Question

我已经尝试在log4j2配置下尝试每天滚动日志文件。日志文件名在环境变量上。下面是我的log4j2.xml文件。

<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
  <Appenders>

    <!-- Console Appender -->
    <Console name="Console" target="SYSTEM_OUT">
      <PatternLayout pattern="%d{yyyy-MMM-dd HH:mm:ss a} [%t] %-5level %logger{36} - %msg%n" />
    </Console>

    <!-- Rolling File Appender -->
    <RollingFile name="RollingFile">
      <FileName>C:/MyLogDir/logs/${env:LOG_FILE_NAME}</FileName>
      <FilePattern>C:/MyLogDir/logs/job_log_collector.%d{yyyy-MM-dd}.log.zip</FilePattern>
      <PatternLayout>
        <Pattern>%d{yyyy-MMM-dd HH:mm:ss a} [%t] %-5level %logger{36} - %msg%n</Pattern>
      </PatternLayout>
      <Policies>
        <TimeBasedTriggeringPolicy interval="1" modulate="true" />
      </Policies>
      <DefaultRolloverStrategy max="5" />
    </RollingFile>

  </Appenders>
  <Loggers>
    <Logger name="com.package.name.AppName" level="debug" additivity="false">
      <AppenderRef ref="RollingFile" />
    </Logger>
  </Loggers>
</Configuration>

但是在尝试运行此命令时我遇到了错误。

我尝试了$ {env：LOG_FILE_NAME}和$$ {env：LOG_FILE_NAME}。但没有运气。

使用下面的依赖项。

<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-api</artifactId>
    <version>2.13.0</version>
</dependency>
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-core</artifactId>
    <version>2.13.0</version>
</dependency>

您可以尝试使用$ {sys：LOG_FILE_NAME}并查看它是否有效吗？
