正在关闭会话。Spring+JPA/Hibernate+Maven

Question

大家好，正在使用Spring+JPA/Hibernate+Maven并尝试从DB获取记录。所以当我朗姆酒时，我的应用程序会出现如下错误

这是一段代码

public class AbstractDao<T> {

/** entity manager */
@PersistenceContext(unitName = "dbschema")
protected EntityManager entityManager;

public Session getHibernateSession() {
    return (Session) this.entityManager.getDelegate();
}



@Repository

public User getUserByName(String userName) {
    Query hqlQuery = getHibernateSession().createQuery("from User where userName=:name").
        setString(RequestParameters.name.name(), userName);

    return (User)hqlQuery.setMaxResults(1).uniqueResult();  
}

Answer 1

暗号对我起作用了：

public class AbstractDao<T> {

/** entity manager */
@PersistenceContext(unitName = "dbschema")
protected EntityManager entityManager;

public Session getHibernateSession() {
    return ((Session) this.entityManager.getDelegate()).getSessionFactory().openSession();
}



@Repository
