解决方案
我认为你多次做了几件事：
 
 
 
这： 
 
 
 < context：annotation-config /> 
  
已包含此项： 
 
 
 <！ - 打开@Autowired，@PostConstruct等支持 - > 
< bean class =org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor/> 
< bean class =org.springframework.context.annotation.CommonAnnotationBeanPostProcessor/> 
  
移除< bean> 定义，并再试一次，也许这就是原因。
 
 
 
 参考：基于注解的容器配置  
 
 
  
 
 
 更新：关于您的新错误：      //static.springsource.org/spring/docs/3.0.x/javadoc-api/index.html?org/springframework/orm/hibernate3/support/HibernateDaoSupport.htmlrel =nofollow>  HibernateDaoSupport  需要 HibernateTemplate 或 SessionFactory 作为依赖关系。你有一个 SessionFactory ，但Spring无法连接它，因为默认情况下，Spring不会自动连接属性，所以你需要手动连接属性或设置< beans default-autowire =byType> （如果使用 byName ，则必须更改SessionFactory bean定义至 id =sessionFactory）

 解决方案 
I think you are doing several things multiple times:



This:
<context:annotation-config/>

already includes this:
<!-- Turn on @Autowired, @PostConstruct etc support -->
<bean class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor" />
<bean class="org.springframework.context.annotation.CommonAnnotationBeanPostProcessor" />

Remove the <bean> definitions and try again, perhaps that's the reason.



Reference: Annotation-based container configuration






Update: about your new error:



HibernateDaoSupport needs either a HibernateTemplate or a SessionFactory as dependency. You have a SessionFactory, but Spring can't wire it because by default, Spring doesn't autowire properties, so you need to either manually wire the property or set <beans default-autowire="byType"> (if you use byName, you will have to change your SessionFactory bean definition to id="sessionFactory")
