org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML doc

org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from class path resource [config/applicationContext.xml]; nested exception is org.springframework.context.annotation.ConflictingBeanDefinitionException:
Annotation-specified bean name 'areaDao' for bean class [com.amt.system.dao.impl.MessageDaoImpl] conflicts with existing, non-compatible bean definition of same name and class [com.amt.system.dao.impl.AreaDaoImpl]

这类错误有很多原因：

1、命名的重复，可能是以上的areaDao重名了

2、缺少，肯能是未找到areaDao的命名的bean

3、applicationContext.xml文件的路径不正确。可以在web.xml中添加配置信息进行指定位置

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>

                classpath:config/applicationContext.xml

        </param-value>
</context-param>
