如何实现“configureAndWatch”在log4j2中 [英] How to implement "configureAndWatch" in log4j2

问题描述

在 log4j 中，有一个功能 configureAndWatch （如下所述），其中没有应用程序服务器重启，日志阈值可以使用默认延迟修改级别。

In log4j, there is a feature configureAndWatch (as mentioned below) where without application server restart, log threshold level can be modified with default delay.

org.apache.log4j.xml.DOMConfigurator.configureAndWatch(log4j.xml path);

这可能在 log4j2 中也可以吗？如果是，那么如何实现呢？

Is this possible in log4j2 as well ? If yes, then how can this be achieved ?

此外，下面是设置和清理的代码行 log4j setup。

Also, below are lines of code for setting up and cleaning up log4j setup.

BasicConfigurator.configure()
BasicConfigurator.resetConfiguration()

如何在 log4j2 中实现这一目标？请帮忙。谢谢。

How can this be achieved in log4j2 ? Please help. Thanks.

Per Log4j2 documentation https://logging.apache.org/log4j/2.x/manual/configuration.html

当从文件配置时，Log4j能够自动检测配置文件的更改并重新配置自身。如果在配置元素上指定了monitorInterval属性并将其设置为非零值，则下次评估和/或记录日志事件时将检查该文件，并且自上次检查后已经过了monitorInterval。下面的示例显示了如何配置属性，以便仅在至少30秒后检查配置文件的更改。最小间隔为5秒。

When configured from a File, Log4j has the ability to automatically detect changes to the configuration file and reconfigure itself. If the monitorInterval attribute is specified on the configuration element and is set to a non-zero value then the file will be checked the next time a log event is evaluated and/or logged and the monitorInterval has elapsed since the last check. The example below shows how to configure the attribute so that the configuration file will be checked for changes only after at least 30 seconds have elapsed. The minimum interval is 5 seconds.

<Configuration monitorInterval="30">
...
</Configuration>
