这是我转换为Spring Data JPA 之前的查询。请注意我以前用来Hibernate.initialize()手动获取小部件的消息的方式。

public Object findWidget(final Widget findMe) {
    Widget widget = getJpaTemplate().execute(new JpaCallback<Widget>() {
        public Widget doInJpa(EntityManager em) throws PersistenceException {
            Query q = em.createQuery("SELECT h FROM " + entityClass.getName() + " h where h.widgetId = ? ");
            q.setParameter(1, findMe.getId());

            Widget found = (Widget)q.getSingleResult();

            //Initialize lazy associations
            if(found!= null){
                Hibernate.initialize(widget.getMessages());
            }

            return found;
        }
    });
    return widget;
}

这就是我的查询功能现在的样子。请注意，没有任何物体可以放入Hibernate.initialize()。

@Query("SELECT h FROM Widget h where h.widgetId = ?1 ")
public AccessPoint findWidget(String widgetId); …
