我最近用 jboss 和 eclipse 尝试了 JPA 程序。为了连接到 MySQL，我在 JBoss 安装目录路径中放入了所需的 mySQL-connector JAR，并在 jboss 的standalone.xml 中添加了配置，如果我从 eclipse 启动 jboss，它启动正常并显示我也配置了连接。但是，如果我添加我的 ejb 程序并启动服务器，它会给我以下错误，当我搜索解决这个问题时，每个论坛都给了我不同的解决方案，但似乎没有解决我的问题。

                 <driver name="mysql" module="com.mysql"/>
            </drivers>
        </datasources>

我在这里错过了什么吗？

我曾尝试使用 mySQL-ds.xml，如果我使用它，它会给出不同的错误，因为数据源无法解析。如果我也知道解决方案会很有帮助，因为我会打包我的程序并进行部署，我不需要再次在 JBoss 中进行 SQL 连接。

谢谢你。

问题是<jta-data-source>java:/</jta-data-source>我需要填写与我提供的相同的名称，<datasource jndi-name="java:/mydb"所以最后自己修复了它，谢谢大家的帮助。

固定的持久性 XML 代码

    <persistence xmlns="http://java.sun.com/xml/ns/persistence"
version="1.0">
<!-- MySQL DataSource -->
<persistence-unit name="STUD">
    <jta-data-source>java:/mydb</jta-data-source>
    <properties>
        <property name="showSql" value="true" />
        <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
    </properties>
</persistence-unit>

希望这会有所帮助

您将需要定义<driver>mysql</driver. 这通常通过定义一个模块来完成。您可以在这里找到所有相关信息 http://bnlconsulting.com/index.php/blog/item/88-jboss-71-adding-mysql-datasource
