我正在努力使记录器在CommandLineRunner中写入文件。日志在SpringApplication.run之前写入，但之后仅进入控制台。

@SpringBootApplication
@Log4j2
public class B4bApplication {

  public static void main(String[] args) {
    log.info("start");
    SpringApplication.run(B4bApplication.class,args);
    log.info("end"); // this comes only in console
  }
}

@Component
@Log4j2
public class B4bProcess implements CommandLineRunner {
  @Override
  public void run(String... args) throws Exception {
    log.info("Start B4B"); // This comes only in console
  }
}

从调试日志中，我看到日志文件已关闭：

DEBUG StatusLogger Started configuration XmlConfiguration[...springframework/boot/logging/log4j2/log4j2.xml] OK.
TRACE StatusLogger Stopping XmlConfiguration[location=C:\git\b4b\src\resources\log4j2.xml]...
TRACE StatusLogger XmlConfiguration notified 3 ReliabilityStrategies that config will be stopped.

我的配置文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
  <Properties>
    <Property name="logDir">logs</Property>
    <Property name="loggingPattern">%d{HH:mm:ss} %-5p %c{1} - %m%n</Property>
  </Properties>
  <Appenders>
    <Console name="STDOUT">
      <PatternLayout pattern="${loggingPattern}"/>
    </Console>
    <File name="general" fileName="${logDir}/general_${sys:COUNTRY_CODE}_${date:yyyyMMdd}.log">
      <PatternLayout pattern="${loggingPattern}"/>
    </File>
  </Appenders>
  <Loggers>

    </Logger>

    </Root>
