为什么我在更新到 5.0 版时得到 "No Persistence provider for EntityManager"?

Why I'm getting a "No Persistence provider for EntityManager" when updated to version 5.0?

我有一个使用“4.3.11.Final”版本 Hibernate 核心和实体管理器的 Maven 项目,一切正常。今天,我把我pom.xml上的这个依赖的版本改成了最新的(5.2.1.Final),我的项目突然失败了:

Exception in thread "main" javax.persistence.PersistenceException:
No Persistence provider for EntityManager named wiki.

版本号是我所做的唯一更改。我需要进行特定设置才能使用 Hibernate 5?我在 5.0 Migration Guide.

上没有找到任何内容

这是我的文件,class 我正在执行:

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;

public final class SchemeExport {

    private static final String PERSISTENCE_UNIT = "wiki";

    public static void main(String... args){
        // fails on the line below
        EntityManagerFactory factory = Persistence.createEntityManagerFactory(PERSISTENCE_UNIT);
        EntityManager manager = factory.createEntityManager();
        manager.close();
        factory.close();
    }
}

您在 persistence.xml 中使用了错误的/旧的持久性提供程序。所以替换

<provider>org.hibernate.ejb.HibernatePersistence</provider>

<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
