Log4J:关闭钩子上的FATAL异常,无法弄清楚原因

Question

我只是将log4j集成到我的应用程序中,并且我将AspectJ设置为使用log4j并最终将所有日志记录从我的主代码中传出.因此,简而言之,我正在设置执行日志条目的方面,然后在短时间内运行我的程序来测试它们.

通常,在这些短期运行期间,我遇到以下异常:

如果您需要查看其他任何内容以确定原因,请告诉我.它并不总是发生,但是当程序运行10-20秒时,它经常发生.我只是不明白为什么会这样.

Answer 1

Log4j2尝试使用shutdown hook正确关闭日志服务.

关闭挂钩是并行执行的,这就是异常不系统的原因.

有关此问题的错误报告.

您可以在配置文件中禁用shutdown hook:

<configuration shutdownHook="disable" ...>

Answer 2

另请参阅log4j2页面上的此链接:

https://logging.apache.org/log4j/2.x/manual/webapp.html

如果包含此依赖项,则不会尝试添加关闭挂接.

<dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-web</artifactId>
        <version>${log4j.version}</version>
