[英]I can't find resolve PersistenceException: No Persistence provider for EntityManager
I found some solutions in the forum, but they not working for me. 我在论坛中找到了一些解决方案,但它们对我不起作用。 The problem is that when I run main method I receive this exception -
问题是当我运行main方法时,我收到此异常-
PersistenceException: No Persistence provider for EntityManager
PersistenceException:没有EntityManager的持久性提供程序
On the imane is my persistance.xml file pat but it's not working. 在imane上是我的persistance.xml文件pat,但是它不起作用。 I try to change file path to web/WEB-INF/classes/META-INF, but its's still not working.
我尝试将文件路径更改为web / WEB-INF / classes / META-INF,但仍无法正常工作。
Here my full persistance.xml source 这是我完整的persistance.xml来源
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence" version="2.1">
<persistence-unit name="StudentPU">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<class>com.classes.StudentBean</class>
<properties>
<property name="hibernate.connection.url" value="jdbc:h2:tcp://localhost/~/Students"/>
<property name="hibernate.connection.driver_class" value="org.h2.Driver"/>
<property name="hibernate.connection.username" value="doncho"/>
<property name="hibernate.connection.password" value=""/>
<property name="hibernate.archive.autodetection" value="class"/>
<property name="hibernate.show_sql" value="true"/>
<property name="hibernate.format_sql" value="true"/>
<property name="hbm2ddl.auto" value="update"/>
<property name="hibernate.temp.use_jdbc_metadata_defaults"
value="false" />
<property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect" />
</properties>
</persistence-unit>
</persistence>
And one more thing? 还有一件事? Why HibernatePersistence is stricken?
为什么HibernatePersistence受到打击? I resolve "stricken" mistake like that -
我这样解决“严重”错误-
Is it correct?
这是正确的吗? But anyway the PersistenceException: No Persistence provider for EntityManager still there.
但是无论如何,PersistenceException:仍然没有EntityManager的持久性提供程序。
I tryed - this and this - nothings happened 我尝试- 这个和这个 -什么都没发生
I would be grateful for any ideas to resolve this error because @Entity method is important to me. 我将不胜感激任何想法来解决此错误,因为@Entity方法对我很重要。
Best regards, 最好的祝福,

The workig method for me is to create this path in my project tree: web/WEB-INF/classes/META-INF/persistence.xml 对我来说,workig方法是在我的项目树中创建以下路径: web / WEB-INF / classes / META-INF / persistence.xml
This is working path when We create Web Applications with IntelliJ. 当我们使用IntelliJ创建Web应用程序时,这是工作路径。
