报错如下:

请问应该怎么解决。我是在别人视频里面看到这样导入可以的,还是说要通过import导入jar包?

上面是你的异常,就是说你的filter找不到! 你的web.xml文件配置有问题! 这样配置filter: <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
