我正在尝试在WildFlt 14.0.1.Final上部署.war，但是我有一个错误，无法弄清它的含义。
我已经部署了JDBC驱动程序，并且我的数据源根据系统输出中的以下消息正确绑定：
20:08:54,471 INFO [org.jboss.as.connector.deployers.jdbc] (MSC service thread 1-2) WFLYJCA0018: Started Driver service with driver-name = mysql
20:08:55,708 INFO [org.jboss.as.connector.subsystems.datasources] (MSC service thread 1-4) WFLYJCA0001: Bound data source [java:/temproDS]
但是，当我尝试部署WAR文件时，会出现以下错误：

看起来您使用的客户端与服务器不匹配。检查服务器版本并更新pom或依赖项中的客户端驱动程序。
