hibernate实现jpa的包，如果不用jpa写代码可以不导入：
jpa是sun推出的标准，hibernate有两种操作数据库的方案，使用自己的方案(sessionfactory/session)不需要这个包，使用实现jpa的方案(entitymanagerfactory/entitymanager)需要这2个包，hibernate-entitymanager用来生成entitymanagerfactory进行各种操作/配置，spring-data-jpa用来创建JpaRepository和JpaSpecificationExecutor的子类在dao层写接口。JpaRepository用来操作数据库，JpaSpecificationExecutor用来生成Specification(spec)，spec可以加入各种条件进行查询。 自己写的接口需要继承JpaRepository和JpaSpecificationExecutor两个接口，这样自己的接口不写任何方法也有默认的方法可以调用。

配置hbm映射文件，配置规则在hibernate-core包的org.hibernate最下面的
hibernate-mapping-3.0.dtd。实际项目复制粘贴即可，样本就在当前文件夹下。
配置hibernate.cfg.xml。(测试时狂报错找不到javassist，重新安装到本地就好了)

测试：
    public void test1(){
            //把hibernatec.cfg.xml放在src/main/resource下即可
        Configuration configuration = new Configuration();
            //源码可以看见configure()加载了"hibernate.cfg.xml"
        configuration.configure();
        SessionFactory sessionFactory = configuration.buildSessionFactory();
        Session se = sessionFactory.openSession();
        Transaction tx = se.beginTransaction();
        Customer c = se.get(Customer.class, 1L);
        c.setCust_name("name222");
        c.setCust_phone("222");
            //save方法返回保存的id值
        Serializable save = se.save(c);
        System.out.println(save);
        tx.commit();
        se.close();
    }
    
    
半xml半注解+jpa配置：
jpa配置必须用entitymanager这个包，jpa增删改查等语法见注解加jpa的代码部分。
这个配置**.hbm.xml用实体类里的注解代替，hibernate.cfg.xml用persistence.xml代替，此文件必须放在META-INF文件夹里，使用maven配置时放在/src/main/resources/META-INF/persistence.xml，ssh整合时persistence.xml可以配置到applciationContextx.xml里。
