Hibernate OGM 介绍
Hibernate 团队对外宣布了一个新的家族成员，Hibernate OGM， OGM 是 Object Grid
Mapping的缩写，它的目标是试图使用 JPA 来操作 NoSQL数据库。
示例代码：
@PersistenceContext EntityManager em;
// the transaction boundary is really here to express the flush time
@Transactional
public void createSomeUser() {
Employer redHat =
em.createQuery("from Employer e where e.name = :name")
.setParamater("name", "Red Hat")
.getSingleResult();
User emmanuel = new User("Emmanuel", "Bernard");
user.setTwitterHandle("emmanuelbernard");
user.setEmployer(redHat);
em.persist(user);
}
//查询
// native query using CypherQLString query = "MATCH ( n:Poem { name:'Portia', author:'Oscar Wilde' } ) RETURN n";
Poem poem = (Poem) em.createNativeQuery( query, Poem.class ).getSingleResult();
