我将 Hibernate/JPA 2.0 与 SQL Server 和 IntelliJ IDEA 一起使用，这是我为测试连接而制作的示例代码：

public class App {
    public static final String SELECT_QUERY = "select u from UsersEntity as u where u.userId = :userId";

    public static void main(String[] args)
    {
        String userId = "1";
        PersistenceProvider persistenceProvider = new HibernatePersistence();
        EntityManagerFactory entityManagerFactory = persistenceProvider.createEntityManagerFactory("newPersistenceUnit", new HashMap());
        EntityManager entityManager = entityManagerFactory.createEntityManager();

        List<UsersEntity> users = entityManager.createQuery(SELECT_QUERY, UsersEntity.class).setParameter("userId", userId).getResultList();
        System.out.println(users);
        entityManager.close();
    }
}

这是我在控制台中收到的内容：

调试时我发现它停在：

EntityManagerFactory entityManagerFactory = persistenceProvider.createEntityManagerFactory("newPersistenceUnit", new HashMap());

知道“newPersistenceUnit”是我的持久性单元的名称。

编辑： 是的，它在 IDEA 之外工作。当我在 IDEA 中使用控制台查询数据时，它可以工作。

我尝试使用下一个代码：

public class HibernateUtil {

private static final SessionFactory sessionFactory;

static {
    try {

        sessionFactory = new Configuration().configure().buildSessionFactory();
    } catch (Throwable ex) {

        System.err.println("Initial SessionFactory creation failed." + ex);
        throw new ExceptionInInitializerError(ex);
    }
}

public static SessionFactory getSessionFactory() {
    return sessionFactory;
}

}

我收到与上面相同的内容，调试停止在：

sessionFactory = new Configuration().configure().buildSessionFactory();

编辑2：

我使用了一个EntityManager：

EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("newPersistenceUnit");

    EntityManager entityManager = entityManagerFactory.createEntityManager();
    entityManager.getTransaction().begin();
    List<AdminsEntity> result = entityManager.createQuery( "from AdminsEntity",     AdminsEntity.class ).getResultList();
    for ( AdminsEntity event : result ) {
        logged = event;
    }
    entityManager.getTransaction().commit();
    entityManager.close();
    return logged;

它停在：

    EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("newPersistenceUnit");

这是我的persistence.xml：

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="2.0">
<persistence-unit name="newPersistenceUnit">
    <class>com.mobitrack.entities.GroupsEntity</class>

        <property name="hibernate.connection.username" value="admin"/>
        <property name="hibernate.connection.password" value="password"/>
        <property name="hibernate.query.factory_class"
                  value="org.hibernate.hql.internal.classic.ClassicQueryTranslatorFactory"/>
    </properties>
</persistence-unit>

有任何想法吗？

此问题可能是由减慢调试器的方法断点引起的。

请仔细检查您是否设置了任何方法断点。在|中禁用toString()评估和备用集合视图选项 也可以提高其性能。SettingsDebugger
