我正在尝试在Wildfly 17.0.1.Final上设置ActiveMQ，以使用Postgresql作为日记。
我已经配置了数据源，并且正在应用程序中使用它。但是，当我将ActiveMQ Artemis配置为使用Postgres数据源作为日志时，遇到了上述问题。设置中缺少什么吗？
版本：
如果我将ExampleDS用作数据源日志，则我的应用程序启动，但是对于Postgresql数据源，则出现错误。

启动Wildfly时，我可以检查是否在公共模式中创建了4个表，但是此后发生了错误。
我还将Postgres模块添加到了Artemis模块中，现在错误是：
Caused by: java.lang.ClassCastException: org.jboss.jca.adapters.jdbc.jdk8.WrappedConnectionJDK8 cannot be cast to org.postgresql.PGConnection
然后我也添加了<module name="org.jboss.ironjacamar.jdbcadapters" />，但是发生相同的错误。

您是否已经尝试使用常规（非XA）驱动程序：
<driver name="postgresql" module="org.postgresql">
<driver-class>org.postgresql.Driver</driver-class>
</driver>
