不是DispatcherServlet只负责管理mvc-config，而ContextLoaderListener负责applicationContext.xml
这是我对web.xml的旧配置：

但是使用此配置，我得到以下异常：

但是在我的web.xml中将applicationContext.xml添加到DispatcherServlet后解决了这个异常，有什么想法吗？
答案 0 :(得分：1)
我猜你使用@Transactional。如果是这样，请注意<tx:annotation-driven />的效果仅限于声明它的上下文。
因此，如果您在@Transactional中声明了webmvc-config.xml的任何bean，则还应在其中添加<tx:annotation-driven />。如果仅在<tx:annotation-driven />中指定applicationContext.xml，则可能会导致您描述的行为。

我认为它与每个具有自己上下文的调度servlet有关，请看这个博客
http://www.dotkam.com/2008/07/09/spring-web-application-context-visibility/
我通过做这样的事情解决了这个问题，我使用监听器来加载我这样的所有上下文文件
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/spring/applicationContext.xml, /WEB-INF/spring/applicationContext-MVC.xml
</param-value>
</context-param>
我创建了一个没有配置配置的虚拟上下文配置，我必须这样做，因为调度servlet抱怨没有上下文配置
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/spring/dummy-config.xml
</param-value>
</init-param>
