org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from URL [file:/F:/MyWorkspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/marbled-cat/WEB-INF/classes/spring-servlet.xml]; nested exception is org.springframework.context.annotation.ConflictingBeanDefinitionException: Annotation-specified bean name 'merchantController' for bean class [org.mcc.merchant.controller.MerchantController] conflicts with existing, non-compatible bean definition of same name and class [org.mcc.campus.manager.controller.MerchantController]

【可能產生原因】
不同的package里有兩個名字相同的類，只是類所在的目錄不同。
【解決方法】
spring管理bean大概類似把bean實例化放到map中，它會以配置的id和name(如果配置的話)為key存放起來,
2個一樣的肯定要成沖突，應該給他們換個名字就成啦
類似於
controller("systemHomeController")
controller("moduleHomeController")
