如何在 Wildfly 10 上设置 MariaDB JNDI？

Question

我正在尝试将我的 Tomcat Web 服务移动到 Wildfly 10。我认为应该将它拖放到 Wildfly 的部署文件夹中，一切都应该没问题，但似乎不是这样。

这是我在 standalone.xml 中的 MariaDB 数据源定义：

<datasource jndi-name="java:jboss/MariaDBDS" pool-name="MariaDBDS">
    <connection-url>jdbc:mariadb://db_ip/db_name</connection-url>
    <driver>mariadb</driver>
    <security>
        <user-name>dbAcc</user-name>
        <password>dbPassword</password>
    </security>
    <validation>
        <valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLValidConnectionChecker"/>
        <validate-on-match>true</validate-on-match>
        <background-validation>false</background-validation>
        <exception-sorter class-name="org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLExceptionSorter"/>
    </validation>
    </datasource>
    <drivers>
        <driver name="mariadb" module="org.mariadb">
            <driver-class>org.mariadb.jdbc.Driver</driver-class>
            <xa-datasource-class>org.mariadb.jdbc.MariaDbDataSource</xa-datasource-class>
        </driver>
    </drivers>

然后我将mariadb-java-client-1.4.6.jar和我的WAR文件放入wildfly/standalone/deployments，启动Wildfly，错误信息进入我的眼中：

07:05:21,137 INFO  [org.wildfly.extension.undertow] (ServerService Thread Pool -- 60) WFLYUT0021: Registered web context: /MySV

    "org.wildfly.data-source.MariaDBDS is missing [jboss.jdbc-driver.mariadb]"
]
}

    "org.wildfly.data-source.MariaDBDS is missing [jboss.jdbc-driver.mariadb]",
    "org.wildfly.data-source.MariaDBDS is missing [jboss.jdbc-driver.mariadb]"
]
}

我无法让我的服务连接到数据库，我错过了任何步骤吗？

如果我查看您的配置，您会将驱动程序设置为模块。因此，您将其创建为服务器中的模块，而不是将其部署为部署文件夹中的单独 jar。

如果您想在驱动程序位于部署文件夹中的位置设置数据源，请执行以下操作：

<datasource jndi-name="java:jboss/MariaDBDS" pool-name="MariaDBDS">
    <connection-url>jdbc:mariadb://db_ip/db_name</connection-url>
    <driver>mariadb-java-client-1.4.6.jar</driver>
    <driver-class>org.mariadb.jdbc.Driver</driver-class>
    <security>
        <user-name>dbAcc</user-name>
        <password>dbPassword</password>
    </security>
    <validation>
        <valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLValidConnectionChecker"/>
        <validate-on-match>true</validate-on-match>
        <background-validation>false</background-validation>
        <exception-sorter class-name="org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLExceptionSorter"/>
    </validation>
</datasource>

不需要单独的驱动程序声明，它全部包含在数据源配置中。
