Jboss 使用新模块依赖项时Wildfly ClassNotFoundException

在为Log4j2添加了一个新模块之后，Wildfly日志在启动时出现了几个ClassNotFoundException。它似乎在该模块中寻找与我新定义的模块无关的其他JavaEE类

以下是一个例外：

最后，我的module.xml如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="org.apache.log4j2">
    <resources>
        <resource-root path="log4j-api-2.0-rc1.jar"/>
        <resource-root path="log4j-core-2.0-rc1.jar"/>
    </resources>
    <dependencies>
        <module name="com.lmax.disruptor"/>
        <module name="javax.api"/>
        <module name="javax.servlet.api"/>
    </dependencies>
</module>

看起来很奇怪，wildfly此时甚至会试图寻找javax.jms.MessageListener，甚至更奇怪的是，它正在“从org.apache.log4j2:main”中寻找它

---

有人知道如何解决这个异常吗？

WildFly没有试图查找

javax.jms.MessageListener

org.apache.logging.log4j.core.net.AbstractJMSReceiver是。我不知道log4j2还有多少其他依赖项，但您至少需要添加

javax.jmx

作为依赖项。

依赖项树（）提到org.jboss.spec.javax.jms:jboss-jms-api_1.1_spec:jar:1.0.1。最终，该模块需要几个库，包括来自第三方的两个新模块。也许有一种更简单的方法可以做到这一点，但它目前正在发挥作用。谢谢。另外，javax.servlet.api依赖项看起来完全没有必要。
