注入的方式 

1   @Resource(name = "sessionFactory")
public void setaaa(SessionFactory sessionFactory){  
   super.setSessionFactory(sessionFactory);  
} 

sessionFactory是spring.xml定义的

2 @Resource(name = "WtdwxxImpl")
    private  T33WtdwxxService t33wtdwxxServ;

-----------------------------------------------------------------------------------------------------------------------------

<context:component-scan base-package="peter.post"></context:component-scan>

组件扫描的时候要特别注意，peter.post下面所有的包和类可以扫描到，但是如果写成peter.post.*，就只能扫描到下面的包，不能扫描到类，因为*表示包名，不表示类名
