Annotation-specified bean name 'userDaoImpl' for bean class [***] conflicts with existing, non-compatible bean definition of same name and class [***]

使用Spring開發的時候報錯如下：

Caused by: org.springframework.context.annotation.ConflictingBeanDefinitionException: Annotation-specified bean name 'userDaoImpl' for bean class [cn.arebirth.impl.UserDaoImpl] conflicts with existing, non-compatible bean definition of same name and class [cn.arebirth.dao.impl.UserDaoImpl]

 

排錯思想：

　　Spring Bean管理的對象名稱相同了，也就是說有兩個類的名字相同。
