java– 添加新的Datasource(mysql)wildfly

我正在尝试将新的数据源mysql jdbc驱动程序添加到我的wildfly服务器

我创建了文件夹wildfly.x.x.x / modules / system / layers / base / com / MysqL / main
我在这里有jdbc jar文件和module.xml

然后将dataresource代码添加到standalone-full.xml(在datareources标记下)

但是当我去wildfly控制面板http：// localhost：9990 / console /
dataresource没有出现,我错过了什么？

我也试图从界面手动添加它我得到了这个错误

Unexpected http response: 500Request{    "address" => [        ("subsystem" => "datasources"),("data-source" => "MysqL")    ],"operation" => "test-connection-in-pool"}ResponseInternal Server Error{    "outcome" => "Failed","failure-description" => "JBAS010440: Failed to invoke operation: JBAS010447: Connection is not valID","rolled-back" => true}
