Question

严重：Exception starting filter struts2这个是什么情况？

十月 18, 2013 5:12:46 下午 org.apache.struts2.spring.StrutsSpringObjectFactory <init>
SEVERE: ********** 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>

我已经把网上说的那5个包都放到lib下了，肿么回事？检查好多遍了 配置都没问题 xml里面也没问题，就是部署完访问jsp页面老是404错误 什么情况咯

Answer 1

你是不是struts2和spring整合呀
web.xml应该没配置好

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

<!-- 默认 是在 /WEB-INF/applicationContext.xml -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/classes/applicationContext.xml
</param-value>
</context-param>
