我使用Wildfly 9.0.2和PostgreSQL 9.5，休眠5.1.0.Final，Java的JDK使用Hibernate PostgreSQL表1.7.0_79无法创建Wildfly
这是我的persistence.xml

这是我弄糊涂了。我已经安装了postgres驱动程序等，但在错误日志中，我看到蜻蜓尝试使用h2驱动程序进行连接。
如果我将hbm2ddl.auto更改为'create'，我可以在日志中看到表'app_user'已创建，但未出现在我的postgresql表中，因此我怀疑它是在H2中创建的。
请帮忙。
代码在哪里指定要使用哪个持久性单元？ （@PersistenceContext（unitName =“MyUnit”））...我也在wildfly中设置连接，因此不在persistence.xml中提供连接字符串，用户名和密码，只是连接的名称。 （其他的hibernate属性是在persistence.xml中指定的，虽然像方言，sql和hibernate.hbm2ddl.auto的格式一样。但是首先，试着在你的服务中用上面的注释来注释EntityManager，可能这就够了 –
Hi @jonmartinsolaas，在我的日志中，它似乎是选择'com.example.flow.persistence.jpa'作为我的持久性单元，这是我唯一的持久性单元。 – VHanded
我认为使用h2的*非常*奇怪，如果你的postgresql持久性单元实际上连接到你的EntityManager，当persistence.xml被读取时，wildfly会记录在那里找到的持久性单元，但为了在你的代码中实际使用它，你必须指向你的EntityManager，它不会自动发生尝试像Nicholas所描述的那样设置驱动程序和连接，然后使用@PersistenceContext注释和unitName参数为你的EntityManager注释（当我看到我有更清晰的错误信息时正在与Glassfish和连接挣扎...） –
