分享SpringMVC Dao层注解，用@Component不报错，而用@Repository报错
各位大神求教，为何我这注解用@Component不报错，而用@Repository报错，下附代码和错误
代码结构：
AbstractDao：
spring-hibernate.xml配置：
Dao层这里继承AbstractDao，用@Repository会报错
AbstractService：
具体错误：org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'uploadController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private me.antinomy.hibernate.service.TmApplicationService me.antinomy.controller.UploadController.applicationService; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'applicationService': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: protected me.antinomy.hibernate.dao.TmApplicationDao me.antinomy.hibernate.service.AbstractService.applicationDao; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'tmApplicationDao' defined in file [D:\EclipseR\hangteng-workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\TinyMobileControlCenter\WEB-INF\classes\me\antinomy\hibernate\dao\TmApplicationDao.class]: Initialization of bean failed; nested exception is org.springframework.aop.framework.AopConfigException: Could not generate CGLIB subclass of class [class me.antinomy.hibernate.dao.TmApplicationDao]: Common causes of this problem include using a final class or a non-visible class; nested exception is org.springframework.cglib.core.CodeGenerationException: java.lang.ClassCastException-->java.lang.Class cannot be cast to java.lang.reflect.ParameterizedType

为什么说我没有权限结贴呢，难道是因为我用QQ登陆的吗。。

您好，已找到问题所在了，是Spring4的问题，主要是CGLIB报错：Could not generate CGLIB subclass of class，最后发现是我Spring版本问题！

不好意思没看到你已经有这个配置了，可以改成整包扫描的啊，还有如果有 <context:component-scan> 后，就可以将 <context:annotation-config> 移除了

加上这个扫描配置
<context:component-scan base-package="整个web包"></context:component-scan>Me_小叶子 2015-10-21

您好，@Repository("applicationDao") 已试过，没有效果！我用的是Spring4.0，现在找到是CGLIB 报错Could not generate CGLIB subclass of class，在这里http://blog.csdn.net/yangxt/article/details/19970323有解释，但是还是没能解决。。

repo是spring-data-jpa，需要增加配置扫描拦截器

@Repository 指定名称：@Repository("applicationDao") 这样试试
