Hibernate 开源对象关系映射框架 ORM
Hibernate是一个开放源代码的对象关系映射框架，它对JDBC进行了非常轻量级的对象封装，使得Java程序员可以随心所欲的使用对象编程思维来操纵数据库。 Hibernate可以应用在任何使用JDBC的场合，既可以在Java的客户端程序使用，也可以在Servlet/JSP的Web应用中使用，最具革命意义的是，Hibernate可以在应用EJB的J2EE架构中取代CMP，完成数据持久化的重任。
Hibernate 5.2.0 发布了。
Java 8 baseline
5.2 moves to Java 8 as its baseline. This means:
The hibernate-java8 module has been removed, and that functionality has been moved intohibernate-core.
Native support for Java 8 date/time types as Query parameters.
Support for streaming (java.util.stream.Stream) query results.
Support for java.util.Optional as return from methods that may return null.
Leveraging Java 8 "default methods" when introducing new methods to extension points.
Consolidating JPA support into hibernate-core.
That effectively means that the hibernate-entitymanager module no longer exists. Its functionality being consumed into hibernate-core.
JCache support
Support for using any JCache-compliant cache impl as a second-level caching provider.
Session-level batch size support
Support has been added for specifying a batch size for write operations per Session.
