ssh三大框架整合 （1）struts2 （2）hibernate5.x （3）spring4.x
ssh框架整合的思想：
web层：struts | V service层（业务逻辑层）：spring | V dao层（数据层）：hibernate，对数据库进行crud操作
1.struts和spring整合：
把struts的action对象创建交给spring进行管理
2.spring和hibernat整合： 把hibernate核心配置文件里面的数据库的配置，直接写在spring配置文件中 第一次访问的时候很慢，因为第一次访问的时候创建sessionFactory对象 把sessionFactory对象创建交给spring管理 在服务器启动的时候创建sessionFactory对象
1.把struts2的action交给spring管理
