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>
分析了下,我是在SystemLaunchListener里面执行的时候,发现ContextLoaderListener
这个监听器没有注册。难道是因为这两个listener是先后执行的?调了下这个两个监听器的顺序,把spring的监听器放在了最前面。重启tomcat,就没有这个报错了。
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.
No WebApplicationContext found: no ContextLoaderListener registered?报错解决,布布扣,bubuko.com
