使用新模块依赖项时Wildfly ClassNotFoundException

标签： jboss wildfly log4j2

在为Log4j2添加新模块后，Wildfly日志在启动时爆发了几个ClassNotFoundException。看起来它正在寻找其他Java EE类的模块，我新定义的模块与之无关。

以下是其中一个例外：

目前我只是尝试部署我的持久性单元存档，以确保我已正确映射所有内容，此存档依赖于Log4j2。在我的持久性存档的META-INF目录中，我有一个jboss-deployment-structure.xml，如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
    <deployment>
        <exclusions>
            <module name="org.apache.log4j"/>
        </exclusions>
        <dependencies>
            <module name="org.apache.log4j2">
                <imports>
                    <include path="META-INF"/>
                </imports>
            </module>
        </dependencies>
    </deployment>
</jboss-deployment-structure>

我的模块由Wildfly中的以下目录结构定义：

$WILDFLY_HOME/modules/org/apache/log4j2/main/
    log4j-api-2.0-rc1.jar
    log4j-core-2.0-rc1.jar
    module.xml

最后我的module.xml如下：

<?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甚至会在这一点上试图寻找javax.jms.MessageListener，甚至更多的是它正在寻找它“来自org.apache.log4j2：main”

有没有人知道如何解决此异常？

1 个答案:

答案 0 :(得分：2)

WildFly并未尝试查找javax.jms.MessageListener org.apache.logging.log4j.core.net.AbstractJMSReceiver。我不知道log4j2有多少其他依赖项，但您至少需要添加javax.jmx作为依赖项。
