日志未写入日志文件：Spring boot 和 log4j.properties

Question

我的 log4j.properties

status=error
name=PropertiesConfig
filters=threshold
filter.threshold.type=ThresholdFilter
filter.threshold.level=debug
appenders=console,rolling
appender.console.type=Console
appender.console.name=STDOUT
appender.console.layout.type=PatternLayout
appender.console.layout.pattern=%d{yyyy-MM-dd'T'HH:mm:ss.SSS}{GMT+0}|%-5p|%c{1}|%M|%L|%replace{%m}{\r}{ }%n
# Rotate log file
appender.rolling.type=RollingFile
appender.rolling.name=LogToRollingFile
appender.rolling.fileName=/var/logs/app.log
appender.rolling.filePattern=/var/logs/backup/app-%d{MM-dd-yyyy}-%i.log
appender.rolling.layout.type=PatternLayout
appender.rolling.layout.pattern=%d{yyyy-MM-dd'T'HH:mm:ss.SSS}{GMT+0}|%-5p|%c{1}|%M|%L|%replace{%m}{\r}{ }%n
appender.rolling.policies.type=Policies
appender.rolling.policies.time.type=TimeBasedTriggeringPolicy
appender.rolling.policies.size.type=SizeBasedTriggeringPolicy
appender.rolling.policies.size.size=100MB
appender.rolling.strategy.type=DefaultRolloverStrategy
appender.rolling.strategy.max=5
#loggers = rolling
rootLogger.level=info
rootLogger.appenderRefs=stdout
rootLogger.appenderRef.stdout.ref=STDOUT
#logger.appenderRefs=rolling
rootLogger.appenderRef.rolling.ref=LogToRollingFile

依赖项：

<dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-web</artifactId>
      <exclusions>
        <exclusion>

    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-log4j2</artifactId>
    </dependency>

Log4 文件正在被选取，我可以看到日志以所需的格式打印，但文件附加器无法正常工作。

我错过了什么？
