Error: Deprecated PersistenceProvider, use HibernatePersistenceProvider instead of HibernatePersistence
提问by user3411221
I think this is a very common problem for all beginners like me. But I could not find a solution. Yet.
我认为这对于像我这样的初学者来说是一个非常普遍的问题。但我找不到解决办法。然而。
File persistence.xml is in src/META-INF/persistence.xml
文件 persistence.xml 位于 src/META-INF/persistence.xml

When I run the code
当我运行代码
try
{
EntityManagerFactory factory = Persistence.createEntityManagerFactory("tarefas");
EntityManager manager = factory.createEntityManager();
manager.close();
factory.close();
System.out.println("Execu??o com sucesso!");
}catch(Exception _Ex)
{
System.out.println("Erro: " + _Ex.getMessage());
}
I get the message
我收到消息

What I'm doing wrong?
我做错了什么？

The problem is in this line from persistence.xml file:
问题出在 persistence.xml 文件中的这一行：
<!-- provedor/implementacao do JPA -->
<provider>org.hibernate.ejb.HibernatePersistenceProvider</provider>
It should be changed to
应该改为
<!-- provedor/implementacao do JPA -->
<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
Even when provider tag is missing in persistence.xml, because of Hibernate bug, Hibernate will use the old ejb provider implementation, and then it will complain about that (schizophrenia)
即使在persistence.xml中缺少provider标签，因为Hibernate bug，Hibernate会使用旧的ejb provider实现，然后它会抱怨（精神分裂症）

The solution by aurelijeis correct, however a bug in Hibernate will incorrectly report an issue even when you specify the correct HibernatePersistenceProvider:
all details on the bug can be found in bug report HHH-9141and exist in Hibernate EntityManager version 4.3.5.Final.
aurelije的解决方案是正确的，但是即使您指定了正确的，Hibernate 中的错误也会错误地报告问题HibernatePersistenceProvider：关于该错误的所有详细信息都可以在错误报告 HHH-9141 中找到，并且存在于 Hibernate EntityManager 版本 4.3.5.Final 中。
