    很纳闷，我在web.xml里面已经声明了ContextLoaderListener 这个监听器。我的web.xml配置文件如下：

	<listener>
		<listener-class>com.j.chat.upgrade.web.core.SystemLaunchListener</listener-class>
	</listener>
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>	
  	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring-config.xml</param-value>
	</context-param>

    网上搜了下web.xml文件里listener的执行顺序。下面是一个可信的说法：

    在java web规范中说明.按照listner,filter,servlet的顺序初始化. 
    其中listener是按照在web.xml中的申明顺序执行的.不存在并发的的情况.
