我正在尝试配置Wildfly 18以将Log4j日志流式传输到Kafka主题。我做了以下配置：
modules \ system \ layers \ base \ org \ apache \ kafka \ clients
<?xml version="1.0" encoding="UTF-8"?>
<module name="org.apache.kafka.clients" xmlns="urn:jboss:module:1.8">
<resources>
<resource-root path="kafka-clients-2.6.0.jar"/>
<resource-root path="snappy-java-1.1.7.3.jar"/>
<resource-root path="lz4-java-1.7.1.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="org.slf4j"/>
</dependencies>
modules \ system \ layers \ base \ org \ apache \ kafka \ log4jappender
<?xml version="1.0" encoding="UTF-8"?>
<module name="org.apache.kafka.log4jappender" xmlns="urn:jboss:module:1.8">
<resources>
<resource-root path="kafka-log4j-appender-2.6.0.jar"/>
<resource-root path="slf4j-log4j12-1.7.30.jar"/>
</resources>
<dependencies>
<module name="org.slf4j"/>
<module name="org.apache.kafka.clients" />
<module name="org.jboss.log4j.logmanager" />
</dependencies>
modules \ system \ layers \ base \ org \ apache \ log4j
<?xml version="1.0" encoding="UTF-8"?>
<module name="org.apache.kafka.log4jappender" xmlns="urn:jboss:module:1.8">
<resources>
<resource-root path="kafka-log4j-appender-2.6.0.jar"/>
<resource-root path="slf4j-log4j12-1.7.30.jar"/>
</resources>
<dependencies>
<module name="org.slf4j"/>
<module name="org.apache.kafka.clients" />
<module name="org.jboss.log4j.logmanager" />
</dependencies>
最后是 modules \ system \ layers \ base \ org \ jboss \ as \ standalone
<?xml version="1.0" encoding="UTF-8"?>
<module name="org.jboss.as.standalone" xmlns="urn:jboss:module:1.6">
...
<dependencies>
...
<module name="org.jboss.logmanager" services="import"/>
<module name="org.jboss.as.jmx" services="import"/>
<module name="org.jboss.as.server" export="true"/>
<module name="org.jboss.vfs" services="import"/>
<module name="org.wildfly.security.elytron-private" services="import"/>
<module name="org.apache.kafka.clients" />
</dependencies>
然后，我在日志子系统中配置了自定义处理程序和异步处理程序。不幸的是，这部分起作用。 Wildfly正在尝试使用新的记录器，但Kafka库找不到 org.apache.kafka.common.serialization.ByteArraySerializer 类。

如果我没有错误地将 org.apache.kafka.clients 设置为 org.jboss.as.standalone 中的依赖项，则可以解决此问题，但不是这样。工作。
