applicationContext.xml和SpringMVC的区别
使用applicationContext.xml文件时是需要在web.xml中添加listener的: <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> 而这个一般是采用非spring mvc架构,如使用struts之类而又想引入spring才添加的,这个是用来加载Application Context。 如果直接采用SpringMVC,只需要把所有相关配置放到springMVC.xml中就OK了。 二、 Spring lets you define multiple contexts in a parent-child hierarchy. The applicationContext.xml defines the beans for the "root webapp context",i.e. the context associated with the webapp. The spring-servlet.xml (or whatever else you call it) defines the beans for one servlet's app context. There can be many of these in a webapp,one per Spring servlet (e.g. spring1-servlet.xml for servlet spring1,spring2-servlet.xml for servlet spring2). Beans in spring-servlet.xml can reference beans in applicationContext.xml,but not vice versa. All Spring MVC controllers must go in the spring-servlet.xml context. In most simple cases,the applicationContext.xml context is unnecessary. It is generally used to contain beans that are shared between all servlets in a webapp. If you only have one servlet,then there's not really much point,unless you have a specific use for it.
上面那一句所以就解释了我们经常看到的 applicationContex.xml中 <context:component-scan base-package="*.*" springMVC.xml中 <context:component-scan base-package="*.*" use-default-filters="false"> <context:include-filter expression="org.springframework.stereotype.Controller" type="annotation" /> </context:component-scan> (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
