spring项目启动报错BeanFactory not initialized or already closed

spring项目启动的时候报如下错误：

java.lang.IllegalStateException: BeanFactory not initialized or already closed - call 'refresh' before accessing beans via the ApplicationContext

我的解决方法：在web.xml中加入如下的就可以正常启动了

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath*:/applicationContext.xml
</param-value>
</context-param>

也不知道包这个错误是什么原因，反正加了这个就可以了，如果大家有新的好的方法，希望能跟我分享下，这里先谢谢了
