logging - 避免出现 log4j2 配置调试消息

Question

我第一次尝试使用 log4j2。它根据我的配置进行日志记录，除了它还会向控制台输出类似配置调试消息的内容:

我的配置文件 preprocessor.log4j2.xml 看起来像:

<?xml version="1.0" encoding="UTF-8" ?>
<configuration status="DEBUG">
    <appenders>

        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{HH:mm:ss.SSS} %-5level %msg%n" />
        </Console>

        <RollingFile name="RollingFileAll" fileName="logs/preprocessor.log"
            filePattern="logs/preprocessor-%d{yyyy-MM-dd-HH}-%i.log.gz">
            <PatternLayout pattern="%d{MM-dd HH:mm:ss.SSS} %-5level %msg%n" />
            <Policies>
                <SizeBasedTriggeringPolicy size="10 MB" />
            </Policies>
        </RollingFile>

    </appenders>
    <loggers>   
        <root level="DEBUG">
            <appender-ref ref="Console" level="INFO" />
            <appender-ref ref="RollingFileAll" />
        </root>
    </loggers>
</configuration>

这就是我从 java 中配置(我知道自动配置)log4j2 的方式:

File file = new File(LOG4J2_CONF_FILE);
Configurator.initialize("preprocessor", null, file.toURI());

我曾尝试添加 EventLogger 记录器并禁用其输出，但没有帮助。您知道如何避免出现此配置调试消息吗？

预先感谢您提供任何提示。

只需删除 status="DEBUG"从配置标签
