使用Hibernate和MS SQL与IntelliJ IDEA的

Question

我使用休眠/ JPA 2.0与SQL Server和IntelliJ IDEA这里是一个示例代码，我做了测试连接：

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(); 
    } 
} 

这里就是我收到的控制台：

调试时我发现，它停在：

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

明知“newPersi stenceUnit“是我的持久性单元的名称。

编辑： 是的，它在IDEA外工作。当我在IDEA中使用控制台查询它的工作原理时。

我使用了下一代码的尝试：

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; 
} 

} 

我收到与上述相同的和调试在停止：

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

EDIT2：

我用一个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"); 

这里是我的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.query.factory_class" 
        value="org.hibernate.hql.internal.classic.ClassicQueryTranslatorFactory"/> 
    </properties> 
</persistence-unit> 

任何想法？

此问题可能是由方法断点引起的，即slow down debugger。

请仔细检查您没有设置任何方法断点。在Settings中禁用toString()评估和备用馆藏查看选项| Debugger也可能会提高其性能。
