注意:

　　Action里面不需要写@Component、@Scope以及@Resource注入相关的属性。因为Action中的属性是通过AutoWire 自动入的，默认按照名字。WebApplication启动时,Spring的的容器就启动了(通过web.xml中配置的istener,并读取了 applicationcontext.xml产生相关的Bean如:ServiceDaoImpl、RegisterUserDaoImpl)但是 Action的产生是通过Struts的Struts-Spring-plugin的插件产生的,产生Action以后，它会自动在Spring的的容器寻找(默认按名字找)自己所需要的属性并注入。当然也可以通过配置Struts.xml中Action的Class(把class指定为 @Component所指定的名字,让Spring容器来生成Action，但需要特别注意的是要在Action中指定 @Scope("prototype"),默认是sington)

注意:

　　　　1、Hibernate4中不能再注入HibernateTemplate了，可以通过注入SessionFactory完成DAO的操作。

　　　 2、当调用HibernateTemplate的save方法的时候，在save()方法内部调用了HibernateTemplate的 executeWithNativeSession()，该方法要传一个实现了HibernateCallBack接口的对象,于是,在 executeWithNativeSession()方法的内部创建了一个实现HibernateCallBack接口的匿名对象,然后调用了 HibernateCallBack接口doInHibernate()方法,该方法通过传进来的session完成了真实的逻辑,然后再返回。

　　　　3、RegisterUserDaoImplTest-context.xml用户JUINT测试。

注意:

　　　OpenSessionInViewFilter把一个Session和一次完整的请求过程对应的线程相绑定,这样就延迟了Session关闭的时间。如果applicationcontext.xml配置文件里面没有配置事务边界,OpenSessionInViewFilter的拦截到任何调用 session的方法,都会把事务当作"Read-Only"处理，这样情况下是不允许写入数据的。如果是这样的话，在 RegisterUserDaoImpl.java中调用通过hibernateTemplate调用save()或者其他修改数据库操作的方法时会抛出异常.
