struts2+hibernate整合错误

struts2+hibernate整合异常

问题

开始做毕设，感觉struts2+hibernate就够用了。今天开始第一步的整合，报错。

错误如下：

11:08:25,066 FATAL StrutsSpringObjectFactory:78 -

********** FATAL ERROR STARTING UP STRUTS-SPRING INTEGRATION **********

Looks like the Spring listener was not configured for your web app!?

Nothing will work until WebApplicationContextUtils returns a valid ApplicationContext.

You might need to add the following to web.xml:?

?? ?<listener>

?? ? ? ?<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

?? ?</listener>
