Log4j 2 – java.lang.NoClassDefFoundError：com / lmax / disruptor / EventTranslatorVararg

使log4j 2记录器异步，但按以下顺序进行：

$ mvn -Dlog4j2.contextSelector=org.apache.logging.log4j.core.async.AsyncLoggerContextSelector -jar app.jar
 
java.lang.NoClassDefFoundError: com/lmax/disruptor/EventTranslatorVararg
    at java.lang.ClassLoader.defineClass1 (Native Method)
    at java.lang.ClassLoader.defineClass (ClassLoader.java:1009)
    at java.security.SecureClassLoader.defineClass (SecureClassLoader.java:174)
    at java.net.URLClassLoader.defineClass (URLClassLoader.java:545)
    at java.net.URLClassLoader.access$100 (URLClassLoader.java:83)
    at java.net.URLClassLoader$1.run (URLClassLoader.java:453)

解

要修复它，请添加disruptor

<dependency>
		<groupId>com.lmax</groupId>
		<artifactId>disruptor</artifactId>
		<version>3.4.2</version>
	</dependency>

注意
阅读本使所有记录器异步
