IDEA java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener

初次使用IDEA搭建SpringMVC项目，以为像普通的Webapplication一样，配置好Tomcat直接运行，没想到报了一个错

[2017-10-30 11:27:29,683] Artifact Spittr:war exploded: Artifact is being deployed, please wait...

查看Tomcat日志：

30-Oct-2017 11:27:29.969 严重 [RMI TCP Connection(3)-127.0.0.1] org.apache.catalina.core.StandardContext.listenerStart Error configuring application listener of class org.springframework.web.context.ContextLoaderListener

查了一下发现是部署的时候少东西，那么就进入

File-Project Structure-Artifacts

会发现在Available Elements目录下有一些包没有拷贝到左侧的output目录

右键Available Element，然后选择Put into xxx就可以了，

 或者右下角应该有一个Fix...按钮，按照提示操作
