Making All Loggers Asynchronous

将原本的log4j2同步日志转化为“完全异步日志模式”。官方文档：

This is simplest to configure and gives the best performance. To make all loggers asynchronous, add the disruptor jar to the classpath and set the system property log4j2.contextSelector to org.apache.logging.log4j.core.async.AsyncLoggerContextSelector.

Log4j-2.9 and higher require disruptor-3.3.4.jar or higher on the classpath. Prior to Log4j-2.9, disruptor-3.0.0.jar or higher was required.
