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 5.0.5 发布，这是 Hibernate ORM 5.0 的第 5 个 bug 修复版本，主要改进：
[HHH-9191] - Inheritance.JOINED + @DiscriminatorColumn : ERROR on quering
[HHH-9302] - SQLGrammarException with @DiscriminatorColumn in an inheritance hierarchy
[HHH-9343] - Case/when in criteria with string literal result fails type checking
[HHH-10157] - Postgis geometry type for JTS geometrys not usable
[HHH-10185] - In nonstrict-read-write mode the remove may be not applied
[HHH-10291] - Partially generated composite attribute is not retrieved after insert
[HHH-10296] - Fix more DB reserved words used by tests
[HHH-10304] - ImplicitCompositeKeyJoinTest#testImplicitCompositeJoin fails due to dialect-specific differences in generated SQL string
[HHH-10309] - HHH-10242 is too aggressive in cases of FIELD access
[HHH-10311] - Primary key length used in unit test is too long for DB2
[HHH-10312] - Unit test failures due to DB problems interpreting proper type for null value when bound to a query
[HHH-10320] - Unit test failures due to feature tested that is not supported by database
[HHH-10321] - HHH-9866 is alive; Wrong join table column names generation with globally_quoted_identifiers
[HHH-10322] - Test failures due to function name differences by dialect
[HHH-10323] - Unit test failure on Oracle because constructor cannot be found
[HHH-10325] - Test failure on MySQL and MariaDB because they do not allow casting as float type
[HHH-10327] - Unit test failures due to date/time precision mismatches
[HHH-10328] - Unit test failure due to database identifier too long
[HHH-10335] - Upgrade to Hibernate Commons Annotations 5.0.1.Final
[HHH-10336] - Upgrade to Jandex 2.0.0.Final
[HHH-10301] - HQLQueryPlan allocates a new ArrayList every time even if it is not required
[HHH-10302] - Lots of allocations of LoadEvent and PostLoadEvent
[HHH-10306] - Use module initializer to add Hibernate 2LC externalizers
[HHH-10308] - Don't make deep copy of property with AttributeConverter if Java type is known to be immutable
[HHH-10313] - Make SessionImplementor extend WrapperOptions
[HHH-10314] - In some cases BatchFetchQueue is created just to try and remove a key
[HHH-10338] - Use an explicit empty object array to prevent the varargs method allocating one
