无法使用Eclipse+；将MySQL连接到Java应用程序；14.0

我无法将Java应用程序连接到运行macOS的本地MySQL 8数据库。我正在使用Eclipse并在WildFly 16.0上部署。当我部署我的应用程序时，控制台抛出以下错误

18:15:00,537 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("add") failed - address: ([

    ]

    ]
}

My

WildFly/modules/system/layers/base/com/mysql/main/module.xml

包含以下内容：

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="com.mysql">
    <resources>
        <resource-root path="mysql-connector-java-8.0.18.jar"/>
    </resources>
    <dependencies>
        <module name="javax.api"/>
        <module name="javax.transaction.api"/>
        <module name="javax.servlet.api" optional="true"/>
    </dependencies>
</module>

在我的Eclipse项目中，

Java资源/src/META-INF/persistence.xml

包含：

<datasource jndi-name="java:jboss/datasources/MYAPP" pool-name="MYAPP" enabled="true" use-java-context="true" statistics-enabled="${wildfly.datasources.statistics-enabled:${wildfly.statistics-enabled:false}}">

我看不出这有什么问题，但对于上面附加的日志，它找不到MySQL连接器。

您好，问题是模块的名称：

<module xmlns="urn:jboss:module:1.1" name="com.mysql">

---

尝试将

定义中的name属性更改为普通mysql

以及

部分中的相应参考

mysql

---

似乎因为name元素是xs:token类型，所以点以某种方式被替换为下划线。

我应该更改什么文件并放在那里？问题是我没有定义一个名为

jboss.jdbc driver.com\u mysql

的模块，我只定义了

com.mysql

，我不知道这是从哪里来的请添加连接池配置您是编辑原始XML还是使用CLI或web界面添加数据源？

"jboss.jdbc-driver.com_mysql
