class path resource [logConfig.xml] cannot be resolved to URL because it does not exist

新项目部署后启动报错：

严重: Exception sending context initialized event to listener instance of class org.springframework.web.util.Log4jConfigListener
java.lang.IllegalArgumentException: Invalid 'log4jConfigLocation' parameter: class path resource [logConfig.xml] cannot be resolved to URL because it does not exist

到部署的tomcat文件夹中查看

编译后的文件中，WEB-INF的classes文件夹中确实是缺失了配置文件。因此，需要在编译前，将配置文件所在的resources目录添加为build path
右键package树上的resources文件夹，->build to path ->Add to…
然后重新部署编译即可。
