獲取此錯誤。試過一切來解決它。通過類似的問題噸看,但沒有結果。也許你們中的一個可能會發現錯誤?先謝謝你。Hibernate SessionFactory註釋錯誤

錯誤日誌:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'studentService': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: miniVLE.dao.MiniVLEDAOImplementation miniVLE.service.StudentService.dao; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'miniVLEDAOImplementation': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.hibernate.SessionFactory miniVLE.dao.MiniVLEDAOImplementation.sessionFactory; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [org.hibernate.SessionFactory] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

哦......真是愚蠢的錯誤!請確保你沒有加倍這在applicationContext.xml

<context:component-scan base-package="miniVLE.controller" /> 
<context:component-scan base-package="miniVLE.service" /> 
<context:component-scan base-package="miniVLE.beans" /> 
<context:component-scan base-package="miniVLE.dao" /> 

天哪..我殺了一天試圖解決它!
