在BaseManager中定义了几个Dao！
protected NewsDao newsDao;
protected NewsClassDao newsclassDao;
protected UserDao userDao;
protected AdminDao adminDao;
protected PhoneUserDao puDao;
并且声明了Setter方法！
然后一个管理员的Service
AdminManagerImpl实现接口AdminManager，并继承自BaseManager
在AdminManagerImpl中引用adminDao中的方法！抛出NullPointerException！
我在Debug中调试发现，Spring容易把Dao成功注入到了BaseManager中，而到了AdminManagerImpl中几个Dao则为null！
请问这是怎么回事呢？
Spring配置文件如下！
[code="java"]

[b]问题补充：[/b]
1楼也是错误的。。。
[code="java"]
[/code]
Debug看来依旧是null！
