这个错误简直要了我的命，我在这里搜索了很多类似的主题，但没有一个对我有帮助！所以，我使用的是spring MVC+Hibernate。请看一下，也许你会发现我错过的错误！这是我的文件：客户端

可以从这里尝试一下这个解决方案：在我的第一个Maven Spring项目中获得一个org.SpringFramework.Beans.Factory.BeanCreationException

只要加上：

<dependency> 
   <groupId>org.springframework</groupId> 
   <artifactId>spring-aspects</artifactId> 
   <version>${your-spring-version}</version> 
</dependency>

创建名为“clients daoimpl”的bean时出错：注入autowired依赖项失败；
