java - 服务器运行时 Hibernate 不创建表

Question

我是 Java EE 的新手，我正在制作一个动态 Web 项目，并且我正在使用 Hibernate 和 MySQL。我已经创建了我的实体，当我运行 Wildfly 时它会打印这个堆栈。

看起来它试图找到要删除的表，然后创建它们，但是当我进入数据库时​​，没有创建任何表。

这是我的persistence.xml 文件

<persistence xmlns="http://java.sun.com/xml/ns/persistence"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"

        <property name="hibernate.show_sql" value="true" />
        <property name="hibernate.hbm2ddl.auto" value="create" />

    </properties>

</persistence-unit>

如果您需要其他东西，请随时提出，非常感谢您能给我的任何帮助。我已经坚持了几个小时。

正如 mh-dev 所说，我需要使用 JTA 数据源，我还必须将 JDBC 驱动程序配置为一个模块才能连接到数据库。
