javax.persistence.Query和javax.persistence.EntityManager都是JAP发布的接口，是用于对象持久化API。
EntityManager接口用于与持久化上下文交互。一个EntityManager实例与持久化上下文相关的。一个持久化上下文是一组中的实体实例的任何持久的实体的身份有一个独特的实体实例。在持久性上下文中，实体实例及其生命周期管理。这个EntityManagerAPI是用于创建和删除持久的实体实例，根据主键找到实体，并查询实体。实体可以通过一个给定的管理设置EntityManager实例是由一个存储单元定义。一个存储单元定义的所有类相关或由应用程序分组设置，且必须放在他们的映射到一个数据库。
Query接口常见用法：
- getResultList()：执行 SELECT 查询并将查询结果作为无类型列表返回。
- getSingleResult ()：执行返回单个无类型结果的 SELECT 查询。
- getFirstResult ()：查询对象设置为检索的第一个结果的位置。如果setFirstResult未应用于查询对象，则返回 0 。
- executeUpdate()：执行更新或删除语句。
- getMaxResults ()：查询对象设置为检索的最大结果数。返回Integer.MAX_VALUEifsetMaxResults未应用于查询对象。
- setFirstResult (int startPosition)：设置要检索的第一个结果的位置。
- setMaxResults (int maxResult)：设置要检索的最大结果数。
- setParameter (int position, Object value)：将参数绑定到位置参数。
- setParameter（字符串名称，对象值）：将参数绑定到命名参数。
EntityManager接口常见用法：
- persist() :添加实体Bean
- flush() ：将实体的改变立刻刷新到数据库中
- merge () :比较麻烦，用好了很不错，配合flush
- Remove() :删除对象
- createQuery() ：返回Query对象,以执行JPQL语句
- createNativeQuery() ：返回Query对象,以执行SQL语句
- refresh() ：刷新实体Bean,以得到对新对象
- contains()： 检测实体当前是否被管理中
- clear() 分离所有当前正在被管理的实体
更多Query和EntityManager用法，请参考api文档：https://www.objectdb.com/api/java/jpa/Query，https://www.objectdb.com/api/java/jpa/EntityManager
