关于extends HibernateDaoSupport

Question

@Component("pagerManager")
public class PagerManager extends HibernateDaoSupport { .....
}@Component("orgManager")
public class OrgManagerImpl implements OrgManager { private HibernateTemplate hTemplate;
private PagerManager pagerManager;
        ......        @Resource(name = "pagerManager")
public void setPagerManager(PagerManager pagerManager) {
this.pagerManager = pagerManager;
}
        ......情况一：
 org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'pagerManager' is defined意味着：extends HibernateDaoSupport的类，不能由spring容器管理 。
我该怎么办！！情况二：
@Component("orgManager")
public class OrgManagerImpl extends PagerManager implements OrgManager {}
异常 需要我 注入 sessionFactory or hebernateTemplate 
情况三 ：
@Component("orgManager")
public class OrgManagerImpl extends PagerManager implements OrgManager {
   
   @Resource(name = "hibernateTemplate")
public void sethTemplate(HibernateTemplate hTemplate) {

Answer 1

..是否能将你的spring的配置文件贴出！你在spring中是否配置了<context:component-scan/>进行注解扫描，对于不是自己定义的类，在spring配置文件是否定义了对象，比如你的hibernateTemplate对象！
@component是个比较大含义,你的三层分的够清晰的话，请使用 @Repository、@Service 和 @Controller 分别表示持久层，服务层和控制层

Answer 2

恩，可以的话，把spring的配置文件贴出来.不然这样都只能猜测，没意思了.

Answer 5

找不到sessionFactory或者是HibernateTeplate。没办法注入到你的manager中.
原因在于HibernateDaoSupport的setter方法前并没有加入@Resource这样的注解，并且它的所有bean方法都是不可改写的，这就相当于你的manager类和HibernateTemplate都被实例化，但manager实例并没有被注入HibernateTemplate.你可以重写一个HibernateDaoSupport 的替代类，然后在你的manager类中直接继承这个类【下面的HDSSuperDao】就Ok了.代码如下：  
@Component
public class HDSSuperDao extends HibernateDaoSupport{

   private HibernateTemplate hibernateTemplate;   
    public HibernateTemplate getHibernateTemplate() {   
        return hibernateTemplate;   
    }   
    @Resource   
   public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {   
       this.hibernateTemplate = hibernateTemplate;   
       }  
}

Answer 6

第二种注入方法：
在你的spring.xml中的hibernateTeplate可以不用定义.也就是
<bean id="hibernateTemplate"  class="org.springframework.orm.hibernate3.HibernateTemplate">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
可以把它去掉.然后写一个类继承HibernateDaoSuport，再注入sessionFacotry也可以，同样在你的manager也继承那个类【HDSSuperDao】就ok啦.代码如下：
@Component
public class HDSSuperDao extends HibernateDaoSupport{

@Resource
public void setSuperSessionFactory(SessionFactory sessionFactory){
System.err.println("sessionFactory======== "+sessionFactory);
super.setSessionFactory(sessionFactory);
}}
